Commando procedure with posterior atrioventricular groove reconstruction.

This case presents a Commando procedure with posterior atrioventricular groove reconstruction in a patient after double-valve replacement performed in another hospital with a posterior atrioventricular groove patch due to mitral annular calcification for aortomitral Streptococcus agalactiae endocarditis. The patient was transferred to our institution on postoperative day 6 under femoro-axillary venoarterial extracorporeal membrane oxygenation with cardiogenic shock and pulmonary oedema due to patch dehiscence and severe periprosthetic mitral leak. To control pulmonary oedema and decrease myocardial tension, left atrial venting was performed in the intensive care unit through a redo sternotomy. After 24 hours, repeat reconstruction surgery was performed after improvement of pulmonary infiltrates and contractility. We alternate operative images with a porcine wet-lab model to facilitate understanding of this advanced reconstruction.
