Only few patients with heart failure with preserved ejection fraction undergo durable mechanical circulatory support implantation. We identified three patients with heart failure with preserved ejection fraction who needed durable mechanical circulatory support as bridge-to-transplant therapy. In two patients with hypertrophic cardiomyopathy, the hypertrophic papillary muscles and myocardium were resected to allow for subsequent left ventricular assist device implantation. In one patient, all visible parts of the mitral valve were additionally resected. The third patient with restrictive cardiomyopathy underwent Berlin Heart Excor BVAD implantation with left atrial cannulation.
仅有少数射血分数保留的心衰患者需要进行持久的机械循环支持植入。我们发现 3 例射血分数保留的心衰患者需要持久的机械循环支持作为移植桥接治疗。在 2 例肥厚型心肌病患者中，切除肥厚的乳头肌和心肌，以便随后植入左心室辅助装置。在 1 例患者中，还切除了二尖瓣的所有可见部分。第 3 例限制型心肌病患者行柏林心脏 Excor BVAD 植入，左心房插管。
