Use of Intracardiac Echocardiography to Evaluate Continuous-Flow Left Ventricular Assist Device Function in a Man With Obesity.

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.
