VENTRICULAR FREE WALL RUPTURE
Abstract
Background: Left ventricular free wall rupture (FWR) is reported to occur in 2–6% of casespresenting with acute myocardial infarction. Mortality of this complication is very high, accounting for20–30% of all infarct related deaths. The objective of our study was to present our surgical experienceof free wall rupture over a period of five years from 2004–2009 Methodology: A review of our recordsover this period of time was undertaken. Results: In our series of six patients collected over this timeperiod, three (50%) presented with hypotension and three (50%) with persistent chest pain. ECGevidence of myocardial infarction was present in 4 (67%) cases, LVH in 2 (33.3%) cases and 2 (33.3%)showed diffuse ST&T changes. Echocardiogram was useful in the diagnosis of rupture but was notconfirmatory. Coronary angiography and left ventriculography was performed in all the patients.Surgery was performed in all cases confirming the FWR. Conclusion: In this small series there was nosurgical mortality which may reflect the favourable prognosis in sub acute rupture wherehaemodynamic stability is achieved with medical therapy prior to surgery.Keywords: Free wall rupture, myocardial infarction, coronary artery bypass graftingReferences
