[Cardiac arrest in a fitness trainer with apical hypertrophic cardiomyopathy associated with cor triatriatum sinister]. / Plötzlicher Herztod einer Fitnesstrainerin mit hypertropher Kardiomyopathie vom apikalen Typ assoziiert mit Cor triatriatum sinister.

We report on a 49-year-old fitness trainer, who was admitted to our hospital after cardiac arrest due to ventricular fibrillation. Return of spontaneous circulation was achieved after immediate cardiopulmonary resuscitation. Coronary angiography could exclude coronary artery disease. Echocardiography demonstrated the presence of apical hypertrophic cardiomyopathy, associated with cor triatriatum sinister. Cardiac magnetic resonance imaging additionally showed marked myocardial fibrosis. The patient underwent placement of an implantable cardioverter-defibrillator and was subsequently discharged for rehabilitation in good condition.
