Surgical management of cardiogenic shock, utilizing mechanical circulatory support, can provide a bridge to recovery, bridge to decision making and/or bridge to transplantation. Despite extracorporeal membrane oxygenation (ECMO) being a reliable, temporary form of support, intracardiac thrombosis is a devastating complication of veno-arterial ECMO. The use of a temporary left ventricular assist device (LVAD), although not immune to thrombosis, helps reduce intracardiac thrombosis, maintaining flow through the heart but importantly allowing for concurrent venting and drainage of the left ventricle. We demonstrate a technique for LV apical cannulation, as a part of a temporary LVAD circuit, aiming to prevent thrombotic complications secondary to cannula angulation.
利用机械循环支持治疗心原性休克的手术管理,可以为恢复、决策制定和/或移植提供桥梁。尽管体外膜氧合 (ECMO) 是一种可靠的临时支持形式,但心内血栓形成是静脉动脉 ECMO 的一种破坏性并发症。使用临时左心室辅助装置 (LVAD) 虽然不能完全避免血栓形成,但有助于减少心内血栓形成,保持心脏血流,但更重要的是允许同时进行左心室的通风和引流。我们展示了一种 LV 心尖插管技术,作为临时 LVAD 回路的一部分,旨在防止由于插管角度引起的血栓形成并发症。
