Abstract
Objective
The aim of this study was to evaluate early clinical outcomes and
echocardiographic measurements of the left ventricle in patients who
underwent left ventricular aneurysm repair using two different techniques
associated to myocardial revascularization.
Methods
Eighty-nine patients (74 males, 15 females; mean age 58±8.4 years;
range: 41 to 80 years) underwent post-infarction left ventricular aneurysm
repair and myocardial revascularization performed between 1996 and 2016.
Ventricular reconstruction was performed using endoventricular circular
patch plasty (Dor procedure) (n=48; group A) or linear repair technique
(n=41; group B).
Results
Multi-vessel disease in 55 (61.7%) and isolated left anterior descending
(LAD) disease in 34 (38.2%) patients were identified. Five (5.6%) patients
underwent aneurysmectomy alone, while the remaining 84 (94.3%) patients had
aneurysmectomy with bypass. The mean number of grafts per patient was
2.1±1.2 with the Dor procedure and 2.9±1.3 with the linear
repair technique. In-hospital mortality occurred in 4.1% and 7.3% in group A
and group B, respectively (P>0.05).
Conclusion
The results of our study demonstrate that post-infarction left ventricular
aneurysm repair can be performed with both techniques with acceptable
surgical risk and with satisfactory hemodynamic improvement.
