Abstract: A 73-year-old male patient presented with shortness of breath at rest resulting from new-onset severe primary mitral regurgitation with a flail posterior leaflet, left ventricular dysfunction, and cardiogenic shock. After initial stabilization in the intensive care unit, multiple treatment options were considered for this patient, all associated with significant mortality. Ultimately, operative mitral valve repair with Impella 5.5 placement was performed for postoperative hemodynamic support. Surgical repair provided elimination of mitral regurgitation. Impella support was maintained for 7 days to provide unloading of the left ventricle. After device removal, the patient had sustained left ventricular recovery with significantly improved ejection fraction. Full left ventricular support and unloading may decrease operative risk and promote left ventricular recovery in patients with severe mitral regurgitation and left ventricular dysfunction. This case emphasizes the value of ventricular unloading to facilitate the recovery of left ventricular function as a treatment option for patients with challenging cases of severe mitral regurgitation and left ventricular dysfunction.
