Multidisciplinary Teamwork in Management of Dislodged Prosthetic Aortic Valve Leaflet.
Ann Thorac Surg Short Rep

Banner University Medical Center, Tucson, Arizona.
Mechanical valve leaflets have the potential to detach and migrate to unintended locations, leading to life- and limb-threatening situations. We report a unique case of a dislodged mechanical aortic valve leaflet in the right iliac artery bifurcation after a redo mitral valve replacement. This was promptly recognized by input from a multidisciplinary team, allowing immediate correction of the aortic valve insufficiency followed by staged retrieval of the dislodged leaflet to avoid vascular complications.

We report a 75-year-old female with a history of two heart operations: aortic valve replacement (St. Jude Medical 21 mm) at the age of 44 years for severe rheumatic aortic stenosis and mitral valve replacement (Carbomedics 29 mm) at the age of 51 years for rheumatic mitral regurgitation. Decades later, she presented with exertional dyspnea.

Background: Contemporary surgical approaches for aortic valve replacement (AVR) include full median sternotomy, hemi-sternotomy, and a right anterior mini thoracotomy (RAMT) approach. We report the midterm outcomes of RAMT for isolated AVR.
Methods: A retrospective study was conducted, reporting the midterm outcomes of patients who underwent isolated RAMT AVR.

We conducted a high-risk redo mitral valve replacement through a right mini-thoracotomy without rib spreading (redo-MICS MVR) under systemic hyperkalemia combined with circulatory arrest to circumvent complications associated with cardioplegia delivery. The patient, a 75-year-old man, had a predicted mortality rate of 20%. Initial antegrade cardioplegia successfully induced cardiac arrest, which was administered every 30 min.

A 71-year-old gentleman with prior bioprosthetic aortic valve replacement was admitted with aortic valve dehiscence and an aortic root abscess. He underwent reoperative sternotomy, aortic root, mitral valve, and hemiarch replacement. To augment hemostasis, we implanted the "Martin Mattress"-a pericardial patch sutured to the fibrous ridge within the innominate vein, superior vena cava, right atrium, right ventricular outflow tract, and pulmonary artery-which is preferred to modified Cabrol fistula techniques in infectious root pathology.
