Impella percutaneous left ventricular assist device for severe acute ischaemic mitral regurgitation as a bridge to surgery

Ischaemic papillary muscle rupture causing acute severe mitral regurgitation (MR) has a dramatic presentation and a very high mortality. Emergent surgical repair improves outcomes, which necessitates robust preoperative stabilisation. Here we discuss a patient with cardiogenic shock with an acute severe MR that was deemed very high risk for emergent valve replacement due to haemodynamic instability and respiratory failure. A percutaneous left ventricular assist device Impella 2.5 (Abiomed, Danvers, MA) drastically improved clinical status, and the patient underwent a successful surgical mitral valve replacement soon after placement of the temporary assist device. Our case highlights that percutaneous ventricular assist devices may help to stabilise patients with severe acute ischaemic MR, and it can serve as a bridge to surgery in high risk patients.
