Premature ventricular contractions: Left ventricular summit

Research output: Chapter in Book/Report/Conference proceedingChapter


A 73 years-old male was referred for catheter ablation of left ventricular summit (LVS) arrhythmias. Typical LVS arrhythmias have a right bundle branch block configuration in lead V1 or a left bundle branch block configuration with early precordial transition (V3 or earlier). The axis is always inferior. Our initial approach to LVS PVCs is to map the coronary venous system. If ablation is unsuccessful or deemed risky in this region, adjacent cardiac structures should be mapped, including the sinuses of Valsalva, left ventricular endocardium, and right ventricular outflow tract.
