Subject was 39 patients who had undergone prosthetic valve replacement at Niigata University Hospital between 1966 and 1993, and died suddenly between 5 months and 20 years after the surgery without any definite causes. The patient population was 19 males and 20 females, age at the surgery ranged between 15 and ss years, and including 23 patients with New York Heart Association functional grading of I or II. Statistical analysis revealed that the year, valve position and kind of prosthetic valve affected the occurrence of sudden death. In the autopsy, only moderate hypertrophy and multiple tiny scars were found in the left ventricle in 6 sudden death patients. On the other hand, in the sudden death patients, more depressed left ventricular function and more frequent ventricular arrhythmia were observed before the death. The results suggests that we might determine high risk group for sudden death, and some possible prevention might be found.}, pages = {281--285}, title = {5)心臓外科領域に於ける突然死(シンポジウム 突然死をめぐる諸問題, 第504回新潟医学会)}, volume = {109}, year = {1995} }
