Abstract

The aim of our study was to identify electrophysiological patterns and technical features of radiofrequency ablation (RFA) of premature ventricular complexes (PVC) originated from left aortic sinus. Patient with frequent PVC (24 591 recorded by Holter ECG) was admitted to RFA of ectopic foci. The mapping of ectopic foci was performed during radiofrequency ablation procedures. The early point was located in the left sinus of Valsalva with presystolic spike advancing QRS complex up to 59 msec. RFA were performed under the control of selective coronary angiography and fluoroscopy, with a positive effect. Thus, radiofrequency ablation of ventricular tachyarrhythmias from aortic root is a safe, highly effective procedure under conditions of well positioning of the ablation catheter, the presence of electrophysiological markers and selective intraoperative coronary angiography.
