Overview

RFCA may be feasible for rare RV PPM-FT VAs; leaves open the need for larger prospective studies to confirm safety and durability.

Key Points

  • This research aims to describe the characteristics and outcomes of catheter ablation for ventricular arrhythmias originating from the right ventricular papillary muscle-false tendon complex.
  • Enrolled 12 patients with ventricular arrhythmias associated with the right ventricular posterior papillary muscle-false tendon complex from a larger cohort of 2184 patients.
  • Used activation mapping, pace mapping, and intracardiac echocardiography to localize arrhythmia origins.
  • Compared findings with a control group of 12 patients with arrhythmias originating from the right ventricular moderate band.
  • PVCs were successfully eliminated by ablation in all patients in the study group.
  • Significant differences in QRS duration and R wave duration were noted between the study group and the control group, particularly in lead V1.
  • A deeper negative component in inferior leads (II, III, aVF) was observed in the study group.

Ventricular arrhythmias originating from the right ventricular posterior papillary muscle-false tendon complex have distinct ECG characteristics and can be successfully treated with radiofrequency catheter ablation.

Cite This Study

Zhang et al. (2026) conducted a case-control in Ventricular arrhythmias (n=24). Ventricular arrhythmias originating from the RV PPM-FT complex vs. Ventricular arrhythmias originating from the RV moderate band was evaluated on Electrophysiological characteristics (QRS duration, R wave duration, RS interval) and ablation success. VAs from the RV posterior papillary muscle-false tendon complex had longer QRS durations than those from the moderate band and were successfully eliminated by ablation in all 12 patients.
