[Long-term course of septal rupture operated on during the acute phase of a myocardial infarct].
Between 1970 and 1979, 28 patients (18 men and 10 women, aged 46 to 76 years, average 62 years) with acute myocardial infarction complicated by septal rupture survived surgery performed during the acute phase. In the same period 62 patients were admitted to the Cardiology Department and were operated early for septal rupture complicating myocardial infarction. The site of infarction was the anterior wall in 22 cases and the posterior wall in 6 cases; septal rupture occurred on average after 4.2 days (range 1 to 10 days); 15 patients including 13 with cardiogenic shock underwent intraaortic balloon pumping for an average of 3:7 (range 1 to 11 days) before surgery; the operation performed after an average interval of 11 days consisted in direct suture of the defect in 3 cases and a patch repair in the other 25 cases, associated in all cases with infarctectomy and LAD coronary bypass grafting in 1 case. The immediate postoperative course was simple; three patients with residual shunts were not reoperated. Five to 14 years later, in 1984, 4 patients had been lost to follow-up; 4 patients had died, 2 of cardiac causes (LVF after 1 year and an arrhythmia after 4 years). Of the 20 survivors, 2 were successfully reoperated (1 coronary bypass after 10 years and 1 false aneurysm after 5 years). Only one patient had recurrent myocardial infarction. The quality and longevity of long-term survival encourage early surgery. The factors affecting long-term survival are discussed: correction of associated valvular defects, resifual shunts, conservation of left ventricular function and evaluation of the coronary circulation.(ABSTRACT TRUNCATED AT 250 WORDS)
