The information was found in the professional literature of japanese society of pediatric cardiology and cardiac surgery(id#(b)(4)).On an unknown date, a (b)(6) pediatric patient with severe mitral regurgitation was implanted with a 27mm masters valve.Eight years later when the patient was (b)(6), the 27mm masters valve was explanted due to severe mitral regurgitation due to muscle resection for subaortic stenosis.A second 27mm prosthetic heart valve was implanted and a residual ventricular septal defect was confirmed.Twenty years later when the patient was (b)(6), severe mitral regurgitation due to prolapse, pulmonary hypertension, and increased shunt between the ventricles were observed.Leakage was observed at the transvalvular level of the left ventricular outflow tract side and perivalvular leakage was observed adjacent to the left ventricular inferior wall.A third mvr with an unknown valve was performed and concomitant interventricular septum closure (vsd) and atrial septum closure(asd)was performed.

The information was found in the professional literature of japanese society of pediatric cardiology and cardiac surgery(id# (b)(4).On an unknown date, a 3-year-old pediatric patient with severe mitral regurgitation was implanted with a 27mm masters valve.Eight years later when the patient was 11-years-old, the 27mm masters valve was explanted due to severe mitral regurgitation due to muscle resection for subaortic stenosis.A second 27mm prosthetic heart valve was implanted and a residual ventricular septal defect was confirmed.Twenty years later when the patient was 3years-old, severe mitral regurgitation due to prolapse, pulmonary hypertension, and increased shunt between the ventricles were observed.Leakage was observed at the transvalvular level of the left ventricular outflow tract side and perivalvular leakage was observed adjacent to the left ventricular inferior wall.A third mvr with an unknown valve was performed and concomitant interventricular septum closure (vsd) and atrial septum closure(asd)was performed.The patient had a history of congenital azygos continuation of the inferior vena cava, polysplenia, and atrial ventricle septal defect.
