Figure 1 A: Baseline 12-lead electrocardiogram reveals frequent premature ventricular complexes of left bundle branch morphology. B, C: Images of the left ventricular outflow tract (LVOT). Cusps are labeled. B: Intracardiac echocardiography. Green lines represent valve cusps. Red arrow indicates the valve strut. Red ablation tags (white location tags) are seen at the septal end of LCC. C: CARTO sound image of the LVOT. White arrow and black arrow indicate LCC and NCC, respectively. The ablation catheter can be seen. LCC = left coronary cusp; NCC = noncoronary cusp; RCC = right coronary cusp.

Figure 2 A: Activation mapping of the left ventricular outflow tract (LVOT). Left: Earliest activation spot on the intracardiac electrogram is seen at –116 ms. Middle: Pace-map. Right: Ablation spot. B: Fluoroscopic image of the LVOT in an anteroposterior view. Edwards SAPIEN 3 valve struts are seen. Ablation catheter is located between the struts and the left sinus of Valsalva.
