Severe Left Vertricular Inflow and Outflow Tract Obstruction due to Congenital Mitral Valve Pathology

An 11-month-old, 6 kg. male child was operated on due to mitral valve pathology, left ventricular outflow tract obstruction and moderate degree of pulmonary hypertension. He had had an open heart surgery and pericardial patch reconstruction of supravalvular aortic stenosis 5 months ago. During reoperation, mitral valve was looking like a granulomatous mass and it was causing significant left ventricular inlet and outlet obstruction. After mitral resection the valve was replaced with St. Jude (no.21) aortic prosthesis. Aortic prosthesis was reversed and implanted on 4-5 mm above the mitral annulus. He was discharged on the 10th day. One year later he became quite active and is growing up without any restriction.
