Abstract

Papillary muscles (PMs) were reported to be origin of ventricular arrhythmia (VA). Radiofrequency (RF) ablation was reported to be acutely effective in eliminating VA. However, the recurrence rate is high. Recently, cryoablation guided by intracardiac echocardiography, 3-dimensional mapping system, and image integration was introduced as alternative strategy for this challenging ablation. We present a case of ventricular tachycardia originating from anterior PM of left ventricle treated by cryoablation guided only by intracardiac echocardiography.

摘要

据报道，乳头肌（PMs）是室性心律失常（VA）的起源。据报道，射频（RF）消融在消除VA方面具有急性疗效。然而，复发率很高。最近，由心腔内超声心动图、三维标测系统和图像整合引导的冷冻消融被引入作为这种具有挑战性的消融的替代策略。我们报告一例仅由心腔内超声心动图引导冷冻消融治疗的起源于左心室前乳头肌的室性心动过速病例。
