BACKGROUND
The implantation of ventricular assist devices is a well-established procedure for the treatment of imminent heart failure. The exact positioning of the left ventricular apical inflow cannula is crucial, because inflow restrictions might occur when the cannula is placed too close to the interventricular septum or a papillary muscle. We report a novel technique using the Tentacles 3-point fixation device for the exposure of the left ventricular apex during ventricular fibrillation under cardiopulmonary bypass.
METHODS
We used the Tentacles, a device originally designed for positioning the heart during off-pump coronary artery bypass grafting, for implantation of a biventricular Berlin Heart Excor in a 64-year-old man. The procedure was successful and echocardiographic examinations documented the exact placement of the left ventricular cannula.
RESULTS AND CONCLUSION
Our new technique ensures a very precise insertion of apical cannulae, because the left ventricular shape and filling are not impaired.
背景
植入心室辅助装置是治疗严重心力衰竭的一种成熟方法。左心室心尖流入插管的精确放置至关重要，因为当插管放置得过于靠近室间隔或乳头肌时可能会出现流入受限。我们报告一种新技术，即在体外循环下心室颤动期间使用触手三点固定装置暴露左心室心尖。
方法
我们使用最初设计用于非体外循环冠状动脉旁路移植术中定位心脏的触手装置，为一名64岁男性植入双心室柏林心脏体外循环辅助装置。手术成功，超声心动图检查记录了左心室插管的精确放置位置。
结果与结论
我们的新技术确保了心尖插管的非常精确的插入，因为左心室的形状和充盈未受损害。
