Aortic insufficiency with recirculation can be difficult to diagnose echocardiographically in patients who have continuous-flow left ventricular assist devices. Transthoracic and transesophageal echocardiography can underestimate its severity; moreover, transesophageal echocardiography necessitates general anesthesia. We report the case of a 58-year-old man with obesity and end-stage nonischemic cardiomyopathy who, after 3 months of support with a continuous-flow left ventricular assist device, underwent intracardiac echocardiography to evaluate complications potentially associated with the device. The findings ruled out aortic insufficiency, preventing an unnecessary valvular intervention.
在使用左心室辅助装置的患者中，伴再循环的主动脉瓣关闭不全在经胸超声心动图和经食管超声心动图检查中很难诊断，这两种方法可能会低估其严重程度；此外，经食管超声心动图需要全身麻醉。我们报告了 1 例 58 岁肥胖男性，患有终末期非缺血性心肌病，在使用左心室辅助装置 3 个月后，进行了心脏内超声检查以评估与装置相关的潜在并发症。结果排除了主动脉瓣关闭不全，避免了不必要的瓣膜干预。
