Iatrogenic chordal rupture with severe mitral regurgitation is a rare but serious complication associated with the use of Impella device. We present a case of a 47-year-old man with ischemic cardiomyopathy who required insertion of an Impella 5.0 device. During Impella support, he developed acute pulmonary edema secondary to newly diagnosed posterior mitral valve chordal rupture and subsequent severe mitral regurgitation. He underwent implantation of a durable left ventricular assist device with concomitant edge-to-edge mitral valve repair through the apex.
医源性腱索断裂伴严重二尖瓣反流是与使用 Impella 装置相关的一种罕见但严重的并发症。我们报告了一例 47 岁男性缺血性心肌病患者，需要插入 Impella 5.0 装置。在 Impella 支持期间，他发生了急性肺水肿，继发于新诊断的后瓣二尖瓣腱索断裂和随后的严重二尖瓣反流。他通过心尖部植入了耐用的左心室辅助装置，并同时进行了二尖瓣瓣环成形术。
