MONOMORPHIC RIGHT-VENTRICULAR TACHYCARDIA IN A PATIENT WITH MITRAL-VALVE PROLAPSE

A patient with mitral valve prolapse and symptomatic ventricular ectop y underwent an electrophysiological study during which a sustained mon omorphic ventricular tachycardia with a left bundle branch block/right axis deviation morphology was induced. This morphology was replicated by pace mapping at the right ventricular outflow tract. To the best o f our knowledge, this finding has not been previously described and su ggests that the association between ventricular arrhythmias and mitral valve prolapse may not necessarily be causal.
