摘要

Background: A left ventricular aneurysm is a mechanical complication of a myocardial infarction that frequently develops on the anterior and apical wall. Survival of 3 to 5 years is 27% and 12%, respectively. Our objective is to report 3 cases of ventricular aneurysms in atypical locations and analyze the survival of these patients. Material and Methods: Three patients with suspicion of ventricular aneurysm after acute myocardial infarction who sought?attention at our institution were included. All underwent transthoracic echocardiograms (TTE), cardiac magnetic resonance (CMR), nuclear cardiology (NC),?coronary angiotomography and cardiac catheterization to assess the location and characteristics of the aneurysms, left ventricular systolic function and the?anatomical and functional condition of the coronary arteries. Results: The mean age of studied patients was 58.33 ± 10.37 years. The locations of the ventricular aneurysms were lateral, inferior and septal. The patients received optimal medical treatment to control heart failure and were discharged in stable condition without early mortality. The mean follow-up was 6.33 years (intervals: 2 - 9) and during this period the patients were in NYHA functional class I/II. Conclusion: Left ventricular aneurysm is a late mechanical complication of an infarction that can develop in an atypical location. Diagnosis is achieved using non-invasive techniques such as TTE, CMR, NC, and coronary angiotomography. No mortality occurred among the patients during medium and long-term follow-up.
