Abstract
LVNC (left ventricular non-compaction) is a rare congenital cardiomyopathy with a reported incidence of 0.05% in adults. It can occur in isolation or affect both ventricles. It’s characterized by prominent LV trabeculae and deep intertrabecular recesses which are filled with blood from the ventricular cavity without evidence of communication to the epicardial coronary artery system. Frequent premature supra ventricular tachycardia as unique finding in LVNC cardiomyopathy is rare manifestation of this disease. We report a case of a frequent persistent supraventricular tachycardia as first manifestation of a patient with LVNC cardiomyopathy in a young healthy woman who despite radio frequency ablation therapy of the supraventricular tachycardia remains symptomatic. The patient was later placed on medical therapy based on a non-cardio selective beta-blocker with a good clinical outcome without recurrent of supra-ventricular arrythmias.
