This video tutorial demonstrates the insertion of a temporary biventricular assist device as a bridge to a heart transplant in a patient with end-stage heart failure with decompensation and increasing pulmonary pressure . This technique utilizes cardiopulmonary bypass to maintain hemodynamic stability throughout the procedure. Transesophageal echocardiography is used to guide the correct positioning of the ventricular cannulae. The cannulation sites include the right ventricle and the pulmonary artery for the right ventricular assist device and the left ventricular apex and the ascending aorta for the left ventricular assist device. The patient is weaned off cardiopulmonary bypass as the biventricular assist device flows are increased to the desired level. Following chest closure, the patient can be ambulatory with the device in situ.
本视频教程演示了在一位终末期心力衰竭伴失代偿和肺动脉压升高的患者中，使用临时双心室辅助装置作为心脏移植的桥接治疗。该技术利用体外循环在整个过程中维持血液动力学稳定。经食管超声心动图用于指导心室插管的正确位置。插管部位包括右心室和肺动脉，用于右心室辅助装置，以及左心室心尖和升主动脉，用于左心室辅助装置。随着双心室辅助装置流量增加到所需水平，患者逐渐脱离体外循环。在胸部关闭后，患者可以在装置原位下地活动。
