title: Tachycardia-induced cardiomyopathy due to repetitive monomorphic ventricular ectopy in association with isolated left ventricular non-compaction.
abstract: Isolated left ventricular non-compaction is a rare genetic disorder manifesting mainly with heart failure, ventricular arrhythmias and systemic embolism. Isolated ventricular tachycardia originating from the right ventricular outflow tract is an arrhythmia that can be treated medically and/or by radiofrequency catheter ablation. Here, we report a case of an asymptomatic 16-year-old boy with a new diagnosis of dilated cardiomyopathy, left ventricular noncompaction and right ventricular outflow tract tachycardia. Electrophysiological studies and radiofrequency ablation of the right ventricular outflow tract tachycardia resulted in normalisation of left ventricular systolic function. This is the first case reporting left ventricular non-compaction in association with tachycardia-induced cardiomyopathy secondary to repetitive monomorphic right ventricular outflow tract tachycardia.
