[Multiple right ventricular thrombi in arrhythmogenic right ventricular cardiomyopathy - a case report]

Typical complications of arrhythmogenic right ventricular cardiomyopathy (ARVC) are heart failure and ventricular arrhythmias which may lead to sudden cardiac death. Intracardiac thrombosis is diagnosed only in 2-4% of patients. The authors present a case of a 50-year-old male admitted to hospital due to symptomatic ventricular tachycardia. Echocardiography and cardiac magnetic resonance showed advanced ARVC with multiple right ventricular thrombi. The biggest one was localized in the inflow tract below the tricuspid valve, whereas the smallest one beneath it, on the inferior wall; the remaining two - in the apex. Chest computed tomography did not confirm pulmonary embolism. Disappearance of thrombi was observed after 4 weeks of anticoagulation. Detection and appropriate treatment of intracardiac thrombi in ARVC may have relevance in prevention of sudden death, not related to arrhythmia, and is of special importance before cardioverterdefibrillator implantation.
