Mitral valve replacement through mini sternotomy after long ECMO course: Case report

Mitral regurgitation (MR) is defined as an abnormal reversal of blood flow from the left ventricle to the left atrium (LA). It is caused by disruption in any part of the mitral valve apparatus. Surgical intervention remains the mainstay of management for severe cases.

We are reporting a case of pneumonia with severe sepsis, that had a complicated hospital course. The patient developed multi-organ failure. Echocardiography on admission showed severe mitral regurgitation. He required early mechanical ventilation and then Veno-venous Extracorporeal Membrane Oxygenation (VV-ECMO) over 29 days. He might be the first case of Coronavirus Disease 2019 (COVID-19) in our hospital. Mitral valve replacement was done after stabilization of the patient and weaning from the ECMO.

Our report demonstrates that the use of a long term VV-ECMO as a bridge for stabilization, facilitates management of the critically ill respiratory failure patient with severe MR and patient outcomes. Still the long-term results and the optimal timing of intervention need more research to define.

Our report demonstrates that the use of a long term VV ECMO facilitates management of patients with respiratory failure associated with severe MR. Future studies focusing on stabilizing such patients, might help to define the optimal timing for intervention in these patients and the long-term outcome.
