Abstract
Over a 28-year period, from November 1957 through November 1985, 15,089 patients underwent operations on the heart and great vessels at The Shanghai Chest Hospital. Herein we examine this experience, with particular attention to factors that affected mortality. Seven thousand two hundred eighty-one patients underwent procedures for mitral stenosis; 149 (2.0%) of these died. Two thousand one hundred thirty-three patients underwent closure of a patent ductus arteriosus; this procedure was associated with 9 deaths (0.4%), 5 of which were caused by massive hemorrhage. After 1964, over 98% of the procedures were accomplished with a locally-manufactured surgical stapler. This device allowed us to perform without any deaths a consecutive series of 1,838 patent ductus arteriosus closures from January 1970 to the end of our study. One thousand five hundred twnety-one patients underwent repair of a ventricular septal defect; 60 died, for a mortality rate of 3.9%. One thousand four hundred thirty-five patients had repair of an atrial septal defect; 13 died during or after operation, for a mortality rate of 0.9%. Higher mortality was observed in groups with severe pulmonary hypertension. Six hundred fifty-one patients were treated for pulm...Continue Reading
