Öğe A new index for the prediction of in-hospital mortality in patients with acute pulmonary embolism: The modified shock index(NLM (Medline), 2023) Türkday Derebey, Sevim; Tokgöz, Hacer Ceren; Keskin, Berhan; Tosun, Ayhan; Hakgör, Aykun; Karagöz, Ali; Akbal, Özgür Yaşar; Bayram, Zübeyde; Efe, Süleyman; Doğan, Cem; Tanboğa, İbrahim Halil; Özdemir, Nihal; Kaymaz, CihangirBACKGROUND: Pulmonary embolism severity index, its simplified version, and shock index have been used for risk stratification in acute pulmonary embolism. In this study, we proposed a modification in severity index and evaluated the correlates and prognostic value of modification in severity index in this setting. METHODS: The study group comprised retrospectively evaluated 181 patients with acute pulmonary embolism. Systematic workup including pulmonary embolism severity index, its simplified version, shock index, biomarkers, and echocardiographic and multidetector computed tomography assessments was performed in all patients. Moreover, we calculated modification in severity index by multiplying original shock index (heart rate/systolic blood pressure ratio) and a third component, 1/pulse oxymetric saturation (pSat O2%) ratio. The primary endpoint was defined as all-cause mortality and hemodynamic collapse during the hospital stay. RESULTS: On the basis of initial risk stratification, ultrasound-assisted thrombolysis, systemic tissue-type plasminogen activator, and unfractionated heparin therapies were utilized in 83 (45.9%), 37 (20.4%), and 61 (33.7%) patients, respectively. The primary end-point occurred in 13 (7.2%) patients. Receiver-operating curve analysis revealed that modification in severity index had the highest area under the curve of 0.739 (0.588-0.890, P =.002) compared with shock index, pulmonary embolism severity index, or its simplified version. The modification in severity index > 0.989 predicted primary endpoint with 73% sensitivity and 54% specificity. CONCLUSIONS: The modification in severity index seems to be a simple, quick, and compre-hensive risk assessment tool for bedside evaluation at initial stratification, in monitoring the clinical benefit from therapies, and decision-making for escalation to other reperfusion strategies in patients with acute pulmonary embolism. However, the prognostic value of modification in severity index needs to be validated with further studies.Öğe A novel composed index to evaluate the right ventricle free-wall adaptation against ventricular wall stress in acute pulmonary embolism(NLM (Medline), 2023) Hakgör, Aykun; Tokgöz Demircan, Hacer Ceren; Keskin, Berhan; Tanyeri, Seda; Kültürsay, Barkın; Tosun, Ayhan; Akbal, Özgür Yaşar; Külahçıoğlu, Şeyhmus; Karagöz, Ali; Türkday Derebey, Sevim; Bayram, Zübeyde; Efe, Süleyman; Doğan, Cem; Tanboğa, İbrahim Halil; Özdemir, Nihal; Kaymaz, CihangirBackground: Pulmonary embolism severity index and simplified pulmonary embolism severity index have been utilized in initial risk evaluation in patients with acute pulmonary embolism. However, these models do not include any imaging measure of right ventricle function. In this study, we proposed a novel index and aimed to evaluate the clinical impact. Methods: Our study population comprised retrospectively evaluated 502 patients with acute pulmonary embolism managed with different treatment modalities. Echocardiographic and computed tomographic pulmonary angiography evaluations were performed at admission to the emergency room within maximally 30 minutes. The formula of our index was as follows: (right ventricle diameter × systolic pulmonary arterial pressure-echo)/(right ventricle free-wall diameter × tricuspid annular plane systolic excursion). Results: This index value showed significant correlations to clinical and hemodynamic severity measures. Only pulmonary embolism severity index, but not our index value, independently predicted in-hospital mortality. However, an index value higher than 17.8 predicted the long-term mortality with a sensitivity of 70% and specificity of 40% (areas under the curve = 0.652, 95% CI, 0.557-0.747, P = .001). According to the adjusted variable plot, the risk of long-term mortality increased until an index level of 30 but remained unchanged thereafter. The cumulative hazard curve also showed a higher mortality with high-index value versus low-index value. Conclusions: Our index composed from measures of computed tomographic pulmonary angiography and transthoracic echocardiography may provide important insights regarding the adaptation status of right ventricle against pressure/wall stress in acute pulmonary embolism, and a higher value seems to be associated with severity of the clinical and hemodynamic status and long-term mortality but not with in-hospital mortality. However, the pulmonary embolism severity index remained as the only independent predictor for in-hospital mortality.Öğe Baseline characteristics, management patterns and outcome in patients with pulmonary embolism and malignancy: insights from a single-centre study(2025) Hakgör, Aykun; Kültürsay, Barkın; Keskin, Berhan; Sekban, Ahmet; Tokgöz, Hacer Ceren; Tanyeri, Seda; Kaymaz, CihangirBackground and aim: Acute pulmonary embolism (PE) is one of the main causes of death in patients with active cancer. In this study, we evaluated the impact of malignancy on the treatment choices, and short- and long-term clinical outcomes in patients with acute PE. Methods: In this study, 872 acute PE patients (age 61.6 ± 16.8 years, female 57.5 %) from different risk and treatment categories were retrospectively analyzed and divided into two groups according to the presence of active malignancy. Results: Active malignancy was documented in 129 (14.8 %) out of the 872 patients. Ultrasound-assisted-thrombolysis (USAT), rheolytic-thrombectomy (RT), systemic-thrombolysis (ST) and anticoagulation-alone therapies were noted in 27.3 %, 6.4 %, 16.6 % and 49.7 % of overall PE patients. RT and anticoagulation therapies were more frequent in patients with malignancy whereas ST and USAT were more frequently used in the other group. Regardless of the presence of malignancy and the treatment modality chosen, significant improvements were achieved in all treatment targets (p < 0.001 for all). Bleeding rates were similar in both groups, while in-hospital and long-term mortality was higher in the malignancy cohort. Active malignancy was found to be an independent predictor for composite of 60-day mortality and PE-related rehospitalization (adjusted OR: 2.43; 95 % CI: 1.32–4.47, p = 0.04) and long-term mortality (adjusted HR: 2.25, 95 % CI: 1.29–3.91, p = 0.004). Conclusion: Concomitant malignancy adversely affects both short- and long-term outcomes in patients with acute PE. Although these patients are more vulnerable, it is possible to achieve satisfactory treatment success with acceptable bleeding rates with the inclusion of catheter-based methods as treatment option.Öğe Clinical, imaging and hemodynamic correlates and prognostic impact of syncope in acute pulmonary embolism: A single-center study(Baycinar Medical Publishing, 2022) Keskin, Berhan; Tokgöz, Hacer Ceren; Akbal, Özgür Yaşar; Hakgör, Aykun; Karagöz, Ali; Kültürsay, Barkın; Tanyeri, Seda; Külahçıoğlu, Şeyhmuş; Tanboğa, İbrahim Halil; Özdemir, Nihal; Kaymaz, CihangirBackground: We aimed to determine the clinical, echocardiographic and hemodynamic correlates of syncope as a presenting symptom in pulmonary embolism and its impact on in-hospital and long-term outcomes. Methods: Between July 2012 and October 2019, a total of 641 patients with PE (277 males, 364 females; median age: 65 years; range, 51 to 74 years) in whom the diagnostic work-up and risk-based management were performed according to the current pulmonary embolism guidelines were retrospectively analyzed. Clinical, laboratory and imaging data of the patients were obtained from hospital database system. Results: Syncope was noted in 193 (30.2%) of patients on admission, and was associated with a significantly higher-risk status manifested by elevated troponin and D-dimer levels, a higher Pulmonary Embolism Severity Index scores, deterioration of right-to-left ventricular diameter ratio, right ventricular longitudinal contraction measures, the higher Qanadli score, and higher rates of thrombolytic therapies (p<0.001) and rheolytic– thrombectomy (p=0.037) therapies. In-hospital mortality (p=0.007) and minor bleeding (p<0.001) were significantly higher in syncope subgroup. Multivariate logistic regression analysis showed that higher Pulmonary Embolism Severity Index scores and right-to-left ventricular diameter ratio were independently associated with syncope, while aging and increased heart rate predicted in-hospital mortality. Malignancy and right-to-left ventricular diameter ratio at discharge, but not syncope, were independent predictors of cumulative mortality during follow-up. Conclusion: Syncope as the presenting symptom is associated with a higher risk due to more severe obstructive pressure load and right ventricular dysfunction requiring more proactive strategies in patients with pulmonary embolism. However, with appropriate risk-based therapies, neither in-hospital mortality nor long-term mortality can be predicted by syncope.Öğe Current insights for catheter-directed therapies in acute pulmonary embolism: Systematic review and our single-center experience(NLM (Medline), 2023) Kaymaz, Cihangir; Tokgöz, Hacer Ceren; Kültürsay, Barkın; Hakgör, Aykun; Keskin, Berhan; Sekban, Ahmet; Karagöz, AliIn this review, the current status of the worldwide experience on different catheter-directed treatment systems utilized as alternative reperfusion methods in acute pulmonary-embolism was evaluated, and the risk stratification algorithms in which catheter-directed treatments may be implemented, source of evidence in this setting, adjudication of benefits and risks of available techniques, and innovative multidisciplinary frameworks for referral patterns and care delivery were discussed. Moreover, our perspectives on risk-based catheter-directed treatment utilization strategies in acute pulmonary embolism were summarized.Öğe Hoarseness as a predictor for pulmonary arterial aneurysm and extrinsic left main coronary artery compression in patients with severe pulmonary hypertension(Turkish Society of Cardiology, 2023) Tokgöz, Hacer Ceren; Tanyeri, Seda; Sekban, Ahmet; Hakgör, Aykun; Kültürsay, Barkın; Keskin, Berhan; Karagöz, Ali; Tosun, Ayhan; Buluş, Çağdaş; Külahçıoğlu, Şeyhmus; Tanboğa, İbrahim Halil; Özdemir, Nihal; Kaymaz, CihangirOBJECTIVE: Pulmonary artery (PA) enlargement is a common finding in patients with severe pulmonary hypertension (PH) and may be associated with extrinsic compression of the left main coronary artery (LMCA-Co) and/or compression of the left recurrent laryngeal nerve resulting in hoarseness named as Ortner syndrome (OS). In this study, we evaluated the diagnostic impact of OS in predicting the PA aneurysm and significant LMCA-Co in patients with PH. METHODS: Our study population comprised retrospectively evaluated 865 with PH confirmed with the right heart catheterization between 2006 and 2022. Patients underwent coronary angiography due to several indications, including the presence of a PA aneurysm on echocardiography, angina symptoms, or the incidental discovery of LMCA-Co on multidetector computed tomography. The LMCA-Co is defined as diameter stenosis ³ 50% in reference distal LMCA segment on two consecutive angiographic planes. RESULTS: The LMCA-Co and hoarseness were documented in 3.8% and 4.3% of patients with PH, respectively. Increasing PA diameter was significantly associated with worse clinical, hemodynamic, laboratory, and echocardiographic parameters. The receiver operating curves revealed that the PA diameter >41 mm was cutoff for hoarseness (AUC: 0.834; sensitivity 69%, specificity 84%, and negative predictive value 98%), and PA diameter >35 mm was cutoff for LMCA-Co >50% (AUC: 0.794; sensitivity 89%, specificity 58 %, and negative predictive value 99%). An odds ratio of hoarseness for LMCA-Co was 83.3 (95% confidence interval; 36.5-190, P < 0.001) with 3.2% sensitivity, 98.7% specificity, and 59% positive and 98% negative predictive values. CONCLUSION: In this study, a close relationship was found between the presence of hoarseness and the probability of extrinsic LMCA-Co by enlarged PA in patients with severe PH. Therefore, the risk of LMCA-Co should be taken into account in patients with PH suffering from hoarseness.Öğe Is it time to reappraise for black-box warning on angiojet rheolytic thrombectomy in patients with pulmonary embolism: a systematic review and meta-analysis(2024) Kaymaz, Cihangir; Kültürsay, Barkın; Tokgöz, Hacer Ceren; Hakgör, Aykun; Keskin, Berhan; Tanyeri, Seda; Karagöz, AliBackground: AngioJet rheolytic thrombectomy (ART) system has been widely used as a catheter-directed treatment (CDT) method in acute pulmonary embolism (PE), however, there has been a controversy regarding the safety of its use. In this systematic review and meta-analysis, we evaluated the efficacy and safety outcomes of ART in patients with PE. Methods: Our meta-analysis have been based on search in the MEDLINE, EMBASE, and Cochrane Library for studies published up to August 2022. The primary outcomes were overall pooled rates of major bleeding (MB) and minor bleeding (mB), worsening renal function (WRF), bradycardia/conduction disturbance (BCD), and PE-related and all-cause mortality in patients who underwent ART. Results: Among the 233 studies documented at initial search, 24 studies were eligible for meta-analysis, and a total of 427 PE patients who underwent ART were evaluated. Overall pooled rates of MB and mB were 9.6% (95% CI 5.9%-15.2%) and 9.2% (95% CI 6.1%-13.6%), transient BCD and WRF were 18.2% (95% CI 12.4%-26%) and 15% (95% CI 10%-21.8%), and PE-related death and all-cause death were 12.7% (95% CI 9.1%-17.3%) and 15% (95% CI 11%-20%), respectively. However, significant heterogeneity and some evidence of funnel plot asymmetry and publication bias were noted for MB, BCD and WRF, but not for PE-related death and all-cause death. Conclusion: Overall pooled rates of bleeding events, BCD and WRF episodes, PE-related death and all-cause death may be considered as encouraging results for efficacy and safety issues of ART utilization in specific scenarios of acute PE, and a reappraisal for black-box warning on ART seems to be necessary.Öğe Maternal and fetal outcomes in pregnant women with pulmonary arterial hypertension: A single-center experience and review of current literature(NLM (Medline), 2022) Tokgöz, Hacer Ceren; Akbal, Özgür Yaşar; Karagöz, Ali; Kültürsay, Barkın; Tanyeri, Seda; Keskin, Berhan; Hakgör, Aykun; Külahçıoğlu, Şeyhmus; Bayram, Zübeyde; Efe, Süleyman Çağan; Doğan, Cem; Tanboğa, İbrahim HalilBACKGROUND: Although pregnancy in women with pulmonary arterial hypertension has been considered a high-risk condition, current data regarding pregnancy with pulmonary arterial hypertension are scarce. In this study, we aimed to evaluate our single-center data on maternal and fetal outcomes in pregnant women with PAH and review currently available risk-based management strategies. METHODS: Our single-center study group comprised 35 women who became pregnant after the diagnosis of pulmonary arterial hypertension or in whom pulmonary arterial hypertension was diagnosed within early post-partum period. Clinical, laboratory, echocardiographic, and hemodynamic characteristics of pregnant and non-pregnant productive women with pulmonary arterial hypertension were compared, and similar comparison was also repeated for survivors and non-survivors in pregnant patient group. RESULTS: Pregnancy was noted in 15% of the 228 females with pulmonary arterial hypertension who were of hormonally productive ages, generally well-tolerated until delivery. Elective abortion and pre-term delivery were documented in 1 (2.8%) and 12 (35.3%) pregnant women, respectively. Switching to sildenafil was the standard medication during pregnancy. Cesarian section was the preferred method of delivery in all pregnant women with pulmonary arterial hypertension and was performed without any complication. Clinic deteoriation within the first week of delivery was observed in 5 (41.6%) patients. Maternal mortality was noted in 13 (37.1%) patients and was documented to cumulate within the first month of delivery. However, any sign predicting post-partum clinical deterioration was not found. No fetal mortality was observed. CONCLUSION: Despite the development of advanced therapies, pregnancy in pulmonary arterial hypertension still carries a high mortality risk and requires multi-disciplinary expert center care with more proactive management strategies.Öğe Prognostic impact of the tricuspid annular plane systolic excursion/pulmonary arterial systolic pressure ratio in acute pulmonary embolism(2024) Kültürsay, Barkın; Keskin, Berhan; Tanyeri, Seda; Külahçıoğlu, Şeyhmus; Hakgör, Aykun; Mutlu, Deniz; Kaymaz, CihangirBackground: Currently available risk stratification models for acute pulmonary embolism (PE) include hemodynamic status, cardiac biomarkers, right ventricle (RV) dysfunction on imaging, and clinical scores. Focusing on the length–tension relationship of the ventricle might have a superior predictive capability over RV dysfunction in terms of mortality and classification of patients with acute PE. In this study, our hypothesis suggests that the tricuspid annular plane systolic excursion (TAPSE)/systolic pulmonary artery pressure (sPAP) ratio has superior predictive capability for in-hospital mortality in patients with acute PE compared to TAPSE or sPAP as distinct measures. Methods: This single-center study comprised retrospectively evaluated 703 patients referred to our tertiary cardiovascular center with acute PE. We divided patients into quartiles based on the TAPSE/sPAP ratio. Different models were developed to quantify the predictive relationship between in-hospital death and echocardiographic measurements. A base model was created with variables including risk status and RV/LV ratio >1. Then, to evaluate the predictive contribution of each measurement; TAPSE/sPAP, TAPSE, and sPAP were sequentially added to the base model. After that, the performance of each model was evaluated. Results: Predictive and discriminative power was the highest in model containing TAPSE/ sPAP. There was still a significant inverse association between TAPSE/sPAP and the risk of in-hospital death even after adjusting for risk status and RV/LV ratio >1. Receiver operating characteristic curve analysis for TAPSE/sPAP revealed the best cut-off value as 0.34. Conclusion: The outcomes of our study reveal that the ratio of TAPSE/sPAP serves as a more potent predictor of mortality than either of the 2 measurements taken separately. The interpretation and utilization of the TAPSE/sPAP cut-off value in acute PE can assist in identifying patients at risk of deterioration and guide the consideration of more intensive treatment options across all risk groups.Öğe Reappraisal of the transthoracic echocardiographic algorithm in predicting pulmonary hypertension redefined by updated pulmonary artery mean pressure threshold(NLM (Medline), 2023) Tanyeri, Seda; Tokgöz, Hacer Ceren; Karagöz, Ali; Akbal, Özgür Yaşar; Keskin, Berhan; Kültürsay, Barkın; Hakgör, Aykun; Külahçıoğlu, Şeyhmus; Çeneli, Doğancan; Tosun, Ayhan; Efe, Süleyman; Bayram, ZübeydeBACKGROUND: Although an adopted echocardiography algorithm based on tricuspid regurgitation jet peak velocity and suggestive findings for pulmonary hypertension has been utilized in the non-invasive prediction of pulmonary hypertension probability, the reliability of this approach for the updated hemodynamic definition of pulmonary hypertension remains to be determined. In this study, for the first time, we aimed to evaluate the tricuspid regurgitation jet peak velocity and suggestive findings in predicting the probability of pulmonary hypertension as defined by mean pulmonary arterial pressure > 20 mm Hg and > 25 mm Hg, respectively. METHODS: Our study group was comprised of the retrospectively evaluated 1300 patients (age 53.1 ± 18.8 years, female 62.1%) who underwent right heart catheterization with different indications between 2006 and 2018. All echocardiographic and right heart catheterization assessments were performed in accordance with the European Society of Cardiology/European Respiratory Society 2015 Pulmonary Hypertension Guidelines. RESULTS: Although tricuspid regurgitation jet peak velocity showed a significant relation with mean pulmonary arterial pressure in both definitions, suggestive findings offered a significant contribution only in predicting mean pulmonary arterial pressure ? 25 mm Hg but not for mean pulmonary arterial pressure > 20 mm Hg. In predicting the mean pulmonary arterial pressure > 20 mm Hg, tricuspid regurgitation jet peak velocity and suggestive findings showed an odds ratio of 2.57 (1.59-4.14, P <.001) and 1.25 (0.86-1.82, P =.16), respectively. In predicting the mean pulmonary arterial pressure ? 25 mm Hg, tricuspid regurgitation jet peak velocity, and suggestive findings showed an odds ratio of 2.33 (1.80-3.04, P <.001) and 1.54 (1.15-2.08, P [removed] 2.8 m/s and tricuspid regurgitation jet peak velocity > 3.4 m/s were associated with 70% and 84% probability of mean pulmonary arterial pressure > 20 mm Hg and 60% and 76% probability of mean pulmonary arterial pressure ? 25 mm Hg, respectively. CONCLUSIONS: In contrast to those in predicting the mean pulmonary arterial pressure ? 25 mm Hg, suggestive findings did not provide a significant contribution to the probability of mean pulmonary arterial pressure > 20 mm Hg predicted by tricuspid regurgitation jet peak velocity solely. The impact of the novel mean pulmonary arterial pressure threshold on the echocardiographic prediction of pulmonary hypertension remains to be clarified by future studies.Öğe Remembering the Occam’s Razor: Could simple electrocardiographic findings provide relevant predictions for current hemodynamic criteria of pulmonary hypertension?(Turkish Society of Cardiology, 2023) Tokgöz, Hacer Ceren; Öcal, Bahadır Erdem; Erkuş, Yiğit Cengiz; Tanyeri Üzel, Seda; Kültürsay, Barkın; Tosun, Ayhan; Keskin, Berhan; Hakgör, Aykun; Sırma, Dicle; Buluş, Çağdaş; Karagöz, Ali; Tanboğa, İbrahim Halil; Külahçıoğlu, Şeyhmus; Bayram, Zübeyde; Sekban, Ahmet; Özdemir, Nihal; Kaymaz, CihangirBackground: We evaluated the predictive value of electrocardiographic (ECG) findings for pulmonary hemodynamics assessed by right heart catheterization (RHC). Methods: Our study population comprised 562 retrospectively evaluated patients who underwent RHC between 2006 and 2022. Correlations between ECG measures and pulmonary arterial systolic and mean pressures (PASP and PAMP) and pulmonary vascular resistance (PVR) were investigated. Moreover, receiver operating characteristic (ROC) curve analysis assessed the predictive value of ECG for pulmonary hypertension (PH) and precapillary PH. Results: The P-wave amplitude (Pwa) and R/S ratio (r) in V1 and V2, Ra in augmented voltage right (aVR), right or indeterminate axis, but not P wave duration (Pwd) or right bundle branch block (RBBB) significantly correlated with PASP, PAMP, and PVR (P < .001 for all). The partial R2 analysis revealed that amplitude of R wave (Ra) in aVR, R/Sr in V1 and V2, QRS axis, and Pwa added to the base model provided significant contributions to variance for PASP, PAMP, and PVR, respectively. The Pwa > 0.16 mV, Ra in aVR > 0.05 mV, QRS axis > 100° and R/Sr in V1 > 0.9 showed the highest area under curve (AUC) values for PAMP > 20 mm Hg. Using the same cutoff value, Ra in aVR, Pwa, QRS axis, and R/Sr in V1 showed highest predictions for PVR > 2 Wood Units (WU). Conclusion: In this study, Pwa, Ra in aVR, right or indeterminate axis deviations, and R/Sr in V1 and V2 showed statistically significant correlations with pulmonary hemodynamics, and Ra in aVR, R/Sr in V2 and V1, QRS axis, and Pwa contributed to variance for PASP, PAMP, and PVR, respectively. Moreover, Pwa, Ra in aVR, QRS axis, and R/Sr in V1 seem to provide relevant predictions for PH and precapillary PH.Öğe Right ventricular global work efficiency provides the highest prediction for improvements in right ventricle to left ventricle diameter ratio with acute pulmonary embolism treatments(Oxford University Press, 2023) Keskin, Berhan; Tokgöz, Hacer Ceren; Kültürsay, Barkın; Hakgör, Aykun; Tanyeri, Seda; Tosun, Ayhan; Kaymaz, Cihangir[Abstract Not Available]
