Abstract

Effective myocardial protection and perfusion strategies during minimally invasive mitral valve surgery (Mini-MV) have evolved over the last decade. Our institutional approach for right-sided Mini-MV has been standardized over the last 15 years in more than 4,500 cases. Cardiopulmonary bypass (CPB) is usually instituted by right-sided femoral arterial and venous cannulation with additional cannulation of the right jugular vein in patients with a body weight greater than 75 kg or when a concomitant tricuspid valve (TV) procedure and/or atrial septal defect closure is performed. A single dosage of crystalloid-based cardioplegia [Custodial- histidine-trypthophan-ketoglutarate (Custodial-HTK)] administered via the aortic root in combination with moderate hypothermia (34-35 °C) has become the standard of care for induction and maintenance of myocardial protection at our institution. The present article highlights and discusses the principal techniques of myocardial protection for Mini-MV.

摘要

在微创二尖瓣手术(Mini-MV)期间,有效的心肌保护和灌注策略在过去十年中不断发展。我们机构的右侧微创二尖瓣手术方法在过去 15 年中在超过 4500 例病例中得到了标准化。体外循环(CPB)通常通过右侧股动脉和静脉插管以及体重超过 75 公斤的患者的右侧颈静脉插管或同时进行三尖瓣(TV)手术和/或房间隔缺损关闭来建立。通过主动脉根部给予单次剂量基于晶体的心脏停搏液[Custodial-组氨酸-色氨酸-酮戊二酸(Custodial-HTK)],并结合中度低温(34-35°C),已成为我们机构诱导和维持心肌保护的标准护理。本文重点介绍和讨论了微创二尖瓣手术中心肌保护的主要技术。
