ABSTRACT
Objective: The objective of this study was to present results of surgical
repair of left ventricle aneurysms with or without myocardial revascularization
and or valve replacement.
Material and methods: We analyzed risk factors, clinical conditions,
coronary arteries affected, surgical procedure carried out, morbidity, and mortality
in patients with left ventricle aneurysms treated between January 1, 1998 and
December 31, 2002.
Results: Of 1,620 patients submitted to myocardial revascularization,
24 (18 male and four females), had ventricular aneurysms. Mean age was 59.22
years. One case (4.54%) had mitral valve lesion, while remaining patients had
ischemic heart disease. A total of 77.27% were in functional class III. Left
anterior descending artery was most affected vessel (95.45%). Main location
was anteroapical and anterolateral in 90.9%. Surgery was indicated for angina
in 72.72%, while surgical repair was done for plicature in 10 cases, aneurismectomy
and linear closure in six cases, and resection and geometric reconstruction
in six combined with myocardial revascularization. There were no differences
in times for ischemic period, cardiopulmonary bypass, and length of hospital
stay. There were two deaths: one due to cardiogenic shock and the other 2 months
later due to ventricular fibrillation. Follow-up time was 31.9 months and 85%
of patients were in functional class I.
Conclusions: We concluded that the previously mentioned procedures for
surgical repair of left ventricle aneurysms combined with complete myocardial
revascularization offers improvement in functional class with acceptable morbidity
and mortality rates.
