A 27-year-old male presented to our institution with recurrent unifocal premature ventricular contraction/nonsustained ventricular tachycardia (VT) with associated cardiomyopathy. The patient had undergone three prior ablation procedures with continued arrhythmia. Mapping led to identification of the VT arising from the basal aspect of the left ventricular anterolateral papillary muscle. Conventional ablation techniques were unsuccessful. We incorporated adjunctive ablation techniques in this case that ultimately led to a successful outcome. The present discussion covers the roles of intracardiac echocardiography, induced apnea, and low-ionic irrigation.
一名27岁男性因复发性单灶性室性早搏/非持续性室性心动过速（VT）伴相关心肌病就诊于我院。该患者此前已接受过三次消融手术，但心律失常仍持续存在。标测发现室性心动过速起源于左心室前外侧乳头肌的基部。传统消融技术未成功。在本病例中，我们采用了辅助消融技术，最终取得了成功。本文讨论了心腔内超声心动图、诱发呼吸暂停和低离子灌注的作用。
