K. Matsui, J. H. Kay, M. Mendez, P. Zubiate, N. Vanstrom and T. Yokoyama
Twenty-four patients underwent operation for ventricular septal rupture
secondary to acute myocardial infarction. There were 14 hospital survivors
(58%) and two late deaths (8%). There were eight hospital deaths (62%) of
13 patients referred in cardiogenic shock, but only two deaths (18%) of 11
patients not in shock at time of referral. All 12 current survivors showed
clinical improvement, and 11 of them are in New York Heart Association
functional class I or II. Eleven patients had bedside catheterization with
a balloon catheter and were operated on immediately thereafter, and eight
survived (73%) with no late deaths at five years. With formal heart
catheterization followed by operation, there were only six survivors of 13
operated on (46%).
