    (Elsevier Science, 2022) Lashkarinia, S. Samaneh; Çiçek, Murat; Köse, Banu; Rezaeimoghaddam, Mohammad; Hekim Yılmaz, Emine; Aydemir, Numan Ali; Rasooli, Reza; Özkök, Serçin; Yurtseven, Nurgül; Erdem, Hasan; Pekkan, Kerem; Şaşmazel, Ahmet
    Objectives: To evaluate the hemodynamicdynamic advantage of a new Fontan surgical template that is intended for complex single-ventricle patients with interrupted inferior vena cava-azygos and hemi-azygos continuation. The new technique has emerged from a comprehensive pre-surgical simulation campaign conducted to facilitate a balanced hepatic flow and somatic Fontan pathway growth after Kawashima procedure. Methods: For 9 patients, aged 2 to18 years, majority having poor preoperative oxygen saturation, a pre-surgical computational fluid dynamics customization is conducted. Both the traditional Fontan pathways and the proposed novel Y-graft templates are considered. Numerical model was validated against in vivo phase-contrast magnetic resonance imaging data and in vitro experiments. Results: The proposed template is selected and executed for 6 out of the 9 patients based on its predicted superior hemodynamic performance. Pre-surgical simulations performed for this cohort indicated that flow from the hepatic veins (HEP) do not reach to the desired lung. The novel Y-graft template, customized via a right- or left-sided displacement of the total cavopulmonary connection anastomosis location resulted a drastic increase in HEP flow to the desired lung. Orientation of HEP to azygos direct shunt is found to be important as it can alter the flow pattern from 38% in the caudally located direct shunt to 3% in the cranial configuration with significantly reversed flow. The postoperative measurements prove that oxygen saturation increased significantly (P-value = 0.00009) to normal levels in 1 year follow-up. Conclusions: The new Y-graft template, if customized for the individual patient, is a viable alternative to the traditional surgical pathways. This template addresses the competing hemodynamic design factors of low physiological venous pressure, high postoperative oxygen saturation, low energy loss and balanced hepatic growth factor distribution possibly assuring adequate lung development.

    Ligation of patent ductus arteriosus through anterior thoracotomy in preterm infants: A 10-year experience
    (Cambridge University Press, 2021) Selçuk, Arif; Çiçek, Murat; Yurdakök, Okan; Kılıç, Yiğit; İzgi Coşkun, Filiz; Erdem, Hasan; Sarıtaş, Türkay; Hekim Yılmaz, Emine; Korun, Oktay; Altın, Hüsnü Fırat; Şaşmazel, Ahmet; Aydemir, Numan Ali
    Objective: The aim of this study is to report on the short-term and mid-term outcomes of preterm infants who underwent patent ductus arteriosus ligation through anterior mini-thoracotomy. Methods: Data for 103 preterm infants who underwent patent ductus arteriosus clipping through an anterior mini-thoracotomy at the 2nd intercostal space between 2009 and 2019 were retrospectively reviewed. The patients were divided into two groups according to their weight at the time of surgery. The complications, morbidity, and mortality rates of each group were compared at postoperative day 30 and at the end of 1 year after surgery. Results: During the operation, the median weight of the patients was 900 g (IQR 800-1125 g), the median age was 21 days (IQR 14.5-29 days). The lowest body weight was 460 g. In three patients (3%), there was intraoperative bleeding from the patent ductus arteriosus that required transition to median sternotomy. In one patient (1%) a residual patent ductus arteriosus that required reoperation was observed. Twelve patients (12%) died in the first 30 days postoperatively. Six patients (6%) died between the postoperative day 30 and 1 year. There was no statistically significant difference in the rates of mortality, morbidity, and complication between the groups. Conclusions: Based on our observations of over a hundred preterm infants with patent ductus arteriosus over a decade, ligation through anterior mini-thoracotomy is the main surgical procedure of choice for this patient group in our clinic. Our findings demonstrate the safety of this approach and we believe that it can be successfully replicated in other institutions.

    (Bayçınar Tıbbi Yayıncılık, 2014) Demir, Fadli; Demir, Halil Ibrahim; Yücel, İlker Kemal; Dedeoğlu, Reyhan; Erdem, Abdullah; Aydemir, Numan Ali; Çelebi, Ahmet
    Amaç: Bu çalışmada Scimitar sendromu tanısı konulmuş hastalar değerlendirildi.Ça­lış­ma­pla­nı:­Çalışmaya Ocak 2003 - Aralık 2011 tarihleri arasında kliniğimizde Scimitar sendromu tanısı konulmuş ortalama ağırlıkları 16.7±21.8 kg olan, 12 hasta (8 kız, 4 erkek; ort. yaş 4.0±4.8 yıl; dağılım 1 ay - 16 yıl), alındı. Hastaların klinik bulguları, fizik muayene, telekardiyografi, ekokardiyografi, kalp kateterizasyonu ve cerahi bulguları ve izlem verileri geriye dönük olarak gözden geçirildi.Bul gu lar: On iki hastadan beşi (%42) infantil tip ve yedisi (%58) çocuk/erişkin tip Scimitar sendromu olarak değerlendirildi. İnfantil tipteki hastaların tümünde taşipne ve kalp yetersizliği bulguları varken, çocuk/erişkin tipteki hastaların birinde tekrarlayan alt solunum yolu enfeksiyonu öyküsü vardı. Ek kardiyak defektler hastaların yedisinde atriyal septal defekt, birinde aort koarktasyonu, ikisinde patent duktus arteriyozus ve birinde ventriküler septal defekt ile pulmoner atrezi idi. Bir hastada iki taraflı Scimitar sendromu vardı. İnfantil Scimitar sendromlu hastaların tümü şiddetli pulmoner hipertansiyonlu iken, çocuk/erişkin tipteki hastalardan biri hafif pulmoner hipertansiyonlu idi. Aortopulmoner kollateral arter saptanan dokuz hastadan altısında arter transkateter yolla kapatıldı. On hastaya (%83) cerrahi girişim uygulandı. İnfantil Scimitar sendromlu bir hasta ameliyat sonrası erken dönemde, ameliyat edilmeyen iki taraflı Scimitar sendromlu diğer bir hasta ise takipte akciğer enfeksiyonu nedeniyle kaybedildi.So nuç: Scimitar sendromu farklı klinik tablolarla seyredebilen nadir bir sendromdur. Çocuk/erişkin tip hastalığı olan hastalar sıklıkla asemptomatiktir; ancak tekrarlayan akciğer enfeksiyonları da izlenebilir. Aortopulmoner kollateral oklüzyon semptomatik iyileşme sağlayabilse de özellikle Scimitar veni tıkanmış ve ilave kardiyak anomalisi bulunan hastalarda cerrahi gerekir.

    Sol atriyal izomerik olguların retrospektif değerlendirilmesi
    (2017) Erdem, Abdullah; Zeybek, Cenap; Kamalı, Hacer; Yücel, İlker Kemal; Yıldırım, Ali; Aydemir, Numan Ali; Türkoğlu, Halil; Çelebi, Ahmet
    Amaç: Bu çalışmada sol atriyal izomerik hastalarında eşlik eden kardiyak patolojiler değerlendirildi ve takip sonuçları sunuldu. Çalış­ma­ planı:­ Temmuz 2002 - Aralık 2016 tarihleri arasında iki doğumsal kalp hastalıkları merkezinde sol atriyal izomerizmli toplam 72 hasta (25 erkek, 47 kız; ort. yaş 44.6±65.8 ay; dağılım 0 gün - 255 ay) retrospektif olarak incelendi. Olguların klinik, radyolojik, elektrokardiyografik, ekokardiyografik ve anjiyokardiyografik bulguları, cerrahi ve transkateter işlemler ve ameliyat sonrası takip verileri kaydedildi. Bulgu­lar:­ Ortalama takip süresi 108±49.5 (dağılım 12-173) ay idi. Yetmiş iki hastanın dördüne cerrahi gerekmez iken, iki hastaya kalıcı kalp pili takıldı. Cerrahi gereken 68 hastanın 17’si iki ventrikül tamiri adayı iken, geriye kalan 51 hasta tek ventrikül tamiri adayıydı. Yirmi dokuz hastaya Kawashima işlemi uygulandı. Bu hastaların yedisinde pulmoner antegrad akım açık bırakıldı. Dört hastada hepatik venler aynı seansta Fontan dolaşımına dahil edildi. Altı hastada takip sırasında ilerleyici siyanoz nedeniyle hepatik venler, ekstrakardiyak kondüit yardımıyla, pulmoner artere yönlendirildi. Cerrahi sonrasında üç hasta kaybedildi. Hepatik venlerin aynı seansta ya da ikinci bir seansta Fontan dolaşımına dahil edildiği hastalar veya antegrad pulmoner akımın açık bırakıldığı hastalarda mortalite veya ilerleyici siyanoz gözlenmedi. Sonuç:­ İki ventrikül fizyolojisine sahip hastaların genel prognozu mükemmeldir. Ancak, Kawashima işlemi yapılan hastalarda doku oksijenizasyonu düşme eğilimindedir. Bu nedenle, Kawashima işlemi yapılan hastalarda, aynı seansta hepatik venlerin dolaşıma dahil edilmesi veya uygun olgularda antegrad akımın açık bırakılması güvenli bir yaklaşım olarak görünmektedir.

    (Cambridge University Press, 2023) Çiçek, Murat; Önalan, Mehmet Akif; İlker, Yücel; Özkök, Serçin; Özdemir, Fatih; Yurdakök, Okan; Aydemir, Numan Ali; Şaşmazel, Ahmet
    OBJECTIVE: Anomalous aortic origin of the coronary artery is a rare congenital cardiac anomaly. The aim of this study was to present our experience with patients who underwent surgery for the anomalous aortic origin of the coronary artery. METHODS: This was a retrospective review of our experience with patients who had anomalous aortic origin of the coronary artery from 2019 to 2022. RESULTS: Seven patients were managed for anomalous aortic origin of the coronary artery, including five males and two females. The median age of the patients were 16 years (IQR, 14.5-26 years). Five patients had anomalous aortic origin of the right coronary artery and two patients had anomalous aortic origin of the left coronary artery. Five patients were treated surgically, one patient refused surgical treatment despite myocardial ischaemia symptoms, and the other one was not operated because she had no symptoms. Two patients underwent pulmonary root anterior translocation and left main coronary artery unroofing procedure, one patient underwent right coronary artery unroofing procedure, one patient underwent pulmonary artery lateral translocation procedure, and the last patient underwent right coronary artery osteal translocation procedure. The post-operative mortality or myocardial infarction was not observed in any patient. Patients were followed for a median of 10 months (IQR, 6.75-20.5 months) after repair. CONCLUSION: The data suggest that surgical repair of anomalous aortic origin of the coronary artery can be performed confidently and can be very effective for relieving myocardial ischaemia symptoms. Different surgical techniques can be used in anomalous aortic origin of the coronary artery according to the course and origin of the coronary arteries. To the our knowledge, pulmonary root anterior translocation and coronary artery unroofing procedure were performed for the first time in the literature.
