Figure 2

The left panel shows electroanatomic activation map of the aortic root for PVC-1 with the earliest activation and ablation site at the LCC (left anterior oblique view). Corresponding local bipolar electrogram (prematurity of 30 ms) is shown below. The right panel shows posterior view of aortic root map for PVC-2 with the earliest activation and ablation site at the NCC. Corresponding local bipolar electrogram (prematurity of 20 ms) is shown below. The bright red CARTO point denotes ostium of the left main coronary artery. Abbreviations: ABL 1.2 and ABL 3.4 – distal and proximal bipoles of the ablation catheter, LCC/RCC/NCC – left/right/non coronary cusp.
