Heightens caution for steam pops during PVC ablation due to perforation or VSD risk; leaves open optimal prevention strategies.
1.5%) and cardiac perforation in only 1 of these cases (2%).4 Nevertheless, if perforation is caused by popping, the risk of need for surgical repair is higher, as it also was in this case.2
