Does anatomical ablation followed by watchful waiting lead to late elimination of persistent idiopathic PVCs originating from the left ventricular summit?
After an initially unsuccessful anatomical ablation for left ventricular summit PVCs, operators may consider a period of watchful waiting as late elimination of PVCs can occur.
Ablation of premature ventricular complexes (PVCs) originating from left ventricular outflow tract (LVOT)/left ventricular summit (LVS) is challenging with considerable rate of failure. Recently, in a novel approach to ablation of these arrythmias, application of radiofrequency energy to anatomically opposite sites of presumed origin of arrythmia, has been associated with moderate procedure success. Although late elimination of PVCs that are persistent following an ablation procedure has been previously reported, this observation has not been studied sufficiently. In this report, firstly, we present three cases of lately eliminated LVS PVCs, then, we discuss possible mechanism of this observation and conclude that after an initial failed attempt of anatomic ablation, operators may choose a period of watchful waiting before attempting a redo procedure.
Candemır et al. (Tue,) conducted a case report in Idiopathic ventricular arrhythmias originating from left ventricular summit (n=3). Anatomical radiofrequency catheter ablation was evaluated on Late elimination of premature ventricular complexes. Anatomical ablation resulted in the late elimination of premature ventricular complexes in three patients who had persistent arrhythmias immediately following the initial procedure.
