Mahaim pathways are usually right-sided, however several leftsided cases have been reported (2). Conventionally Mahaim pathway ablation is performed with radiofrequency ablation (RFA). We report a patient who presented with a wide QRS tachycardia with left bundle branch block (LBBB) pattern. The electrophysiology study demonstrated Mahaim tachycardia and the patient was successfully treated with cryoablation following a failed attempt with RFA.eninfo:eu-repo/semantics/openAccessMahaim PathwayCryoablation CatheterChildArticle14655455610.5152/akd.2014.5291Q4N/A
