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 presented in cardiogenic shock requiring insertion of extracorporeal membrane oxygenation which was subsequently transitioned to 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. Transthoracic echocardiography at three month showed mild regurgitation.

Sustained ventricular tachycardia and ventricular fibrillation (VF) are life-threatening arrhythmias which remain highly prevalent in patients with advanced heart failure. These ventricular arrhythmias may impair the support provided by CF-LVADs and lead to frequent hospitalizations, antiarrhythmic medication use, external defibrillations, and need for heart transplantation. We report a case in which a patient with a CF-LVAD and an ICD at end-of-life (EOL) presented with asymptomatic low-flow alarms and was found to have VF of unknown duration. Unique in our case was the presence of organized contractility and rhythmic opening of the mitral valve on echocardiogram despite VF on ECG.
