Septal rupture after myocardial infarction: is very early surgery really worthwhile?
Despite numerous publications, mostly with small patient populations, the management of post-infarct septal rupture is still not well defined. Although urgent surgery appears to be the therapy of choice it is still unclear whether surgery very early after septal rupture in patients with severe haemodynamic compromise salvages a significant number of patients. In this paper we present the data from a large population of consecutive patients with post-infarct septal rupture from one cardiac centre. From 1980 through 1989, 108 patients with post-infarct septal rupture were seen at this Regional centre of whom 81 had operative repair; 43 (53%) of these survived the early postoperative period. Of 32 patients with cardiogenic shock who had surgery, early operative mortality in those operated on within 48 h of rupture was 90% (18/20) compared with 33% (4/12) in those operated on later (P less than 0.001). All survivors with pre-operative shock had intra-aortic balloon counter-pulsation before operation. Concomitant coronary artery bypass grafting was not associated with improved survival in our patients. Three patients survived long-term without operation. Analysis of population statistics suggest that approximately 270 patients with post-infarction septal rupture were not transferred from peripheral hospitals to the Regional Cardiothoracic Centre for assessment during this decade.
