Figure 4.

Panel A: Twelve‐leads ECG of a 39‐years‐old female highly symptomatic for frequent premature ventricular complex leading to reduce left ventricular ejection function. A first attempt to ablate PVC failed. Patient was referred to our centre for a second procedure. Panel B: Short axis LGE images of CMR. Before the second ablation a CMR was performed to evaluate left ventricular function. The left ventricular ejection fraction was 43%. A small zone of Late Gadolinum Enhancement was detected in the septal region of the tricuspid annulus (blue arrow). The max depth of the lesion in the septum was 5 mm. Panel C: Cardiac magnetic resonance was repeated 6 mo after the second successful PVC ablation. The left ventricular ejection fraction improved to 57%. The area of Late Gadolinum Enhancement (blue arrow) was larger and deeper (7 mm)
