Root-commando operation with a modified self-assembled aortic root conduit for endocarditis after sutureless aortic valve replacement.

We present a case of a Staphylococcus epidermidis early prosthetic valve endocarditis after minimally invasive sutureless aortic valve replacement. The patient developed a root abscess with a fistula, severe mitral and periprosthetic regurgitations, with a large mitral vegetation and a residual patent foramen ovale. The surgical approach consisted of a redo median sternotomy, explantation of a sutureless aortic prosthesis, resection of an intervalvular fibrosa and anterior mitral leaflet and debridement of an aortic root-left ventricle outflow tract abscess. These procedures were followed by a root-commando procedure with mitral and aortic root placement using a self-assembled mechanical aortic root conduit. The technique used is an alternative to a root-commando procedure performed with an allograft or a Medtronic Freestyle bioprosthesis. The same technique can be utilized with a commercially available stented bioprosthesis.

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.

Cardiac retransplantation.

An orthotopic heart transplant remains the gold standard treatment for patients with end-stage heart failure. Despite significant developments and the widespread use of durable mechanical circulation support, a small number of patients will be considered for a heart retransplant. In this video tutorial, we describe the strategy and technique for patients who have already received an orthotopic heart transplant and who undergo a cardiac retransplant with a modified bicaval anastomosis technique.
