Excerpt
Ablation for papillary muscle (PM) premature ventricular contractions (PVC) is challenging, typically requiring multiple ablation lesions and having a high recurrence rate [
1]. PMs are highly mobile structures that make achieving catheter stability difficult, particularly on the sides of the PM due to the shape of the structure during the occurrence of PVCs [
2]. Creating an accurate activation map is further complicated by the presence of Purkinje network inside the PM that results in rapid conduction and subsequently small differences in activation timing between neighboring sites, producing a wide area of earliest activation [
3]. …
