Because the LVS is an epicardial region, the approach to the LVS may be indirect or direct. The indirect method uses the adjacent structures to achieve closeness to the earliest activation point exiting the arrhythmia source. Because of a lack of such reasonable access points, these were defined as the vertices of the “Bermuda triangle” [69–71]. However, delivery of the proper radiofrequency energy to the arrhythmia source, avoiding at the same time the coronary artery damage, may be a challenge [70,72,73]. Therefore, coronary angiography or cardiac computed tomography imaging is strongly recommended before any procedure within the LVS region [74–81].
