右心室电极相关的三尖瓣反流

右心室(RV)电极相关的三尖瓣反流(TR)是心血管植入式电子装置(CIED)术后并发症之一,其发生机制主要为电极导线对三尖瓣的机械作用和右心室起搏改变了心脏的收缩顺序。电极种类及数量、植入时间、起搏位置及心房颤动等是其危险因素。结合病史、体格检查及辅助检查可作出明确诊断,治疗包括药物治疗、电极复位、拔出及外科手术。本文对近年关于右心室电极相关三尖瓣反流的相关研究作一综述。

Right ventricular lead-related tricuspid regurgitation

Right ventricular (RV) lead-related tricuspid regurgitation (TR) is one of the postoperative complications after implantation of cardiovascular implantable electronic devices (CIED), and the mechanisms whereby include the lead causing mechanical interference to the valve leaflets and RV pacing changing the sequence of contraction of the heart. Types and quantities of the lead, duration of lead placement, pacing position and atrial fibrillation are the risk factors for TR. Combining with the medical history, physical examination and auxiliary examination, we can make a definite diagnosis, and the treatment includes medication, lead reimplantation or extraction and surgery. In this article, we reviewed the recent literatures concerning RV lead-related TR.
