Abstract

From 1979 to 1993, 139 patients had reduction of left ventricular aneurysm (LVA) by plication (PL) (25 cases) linear repair (74 cases) or ventricular reconstruction (VR) (40 cases). Coronary bypass grafting was performed in 89 patients. We retrospectively reviewed our experience in order to identify predictore of early and late outcome and determine whether ventricular reconstruction (VR) can improve postoperative and late prognosis. Operative mortality (OM) was 7.2%. Among 129 hospital survivors, 48 died during FU (LM). OM was related to a more recent myocardial infarction (p=0.0001), a higher residual score (RS) (p=0.02), a lower EF (p=0.038), a higher left ventricular score (p=0.059), a three-system disease (TSD) (p=0.09) and a right coronary disease (RCD) (p=0.13). At Multivariate Analysis (Stepwise Logistic Regression) TSD (p=0.001), RCD (p=0.008) and RS (p=0.04) are independent risk factors. Actuarial survival rate at 15 years is 33.5+/-6.9% (OM included). According to the comparison of the Actuarial Curves (Tests of Mantel and Breslow, OM excluded) the most significant risk factors were: non use of left internal mammary artery (LIMA) (p=0.004), VR (p=0.01), TSD (p=0.03) and higher NYHA class (p=0.019).

Atrial Fibrillation

Atrial fibrillation is a common arrhythmia that is associated with substantial morbidity and mortality, particularly due to stroke and thromboembolism. Here is the latest research.

Aneurysm

Aneurysms are outward distensions or bulges that occurs in a weakened wall of blood vessels. Discover the latest research on aneurysms here.

Arrhythmia

Arrhythmias are abnormalities in heart rhythms, which can be either too fast or too slow. They can result from abnormalities of the initiation of an impulse or impulse conduction or a combination of both. Here is the latest research on arrhythmias.

Cardiac Aneurysm

Aneurysm refers to a bulge of the wall or lining of a vessel commonly occurring in the blood vessels at the base of the septum or within the aorta. In the heart, it usually arises from a patch of weakened tissue in a ventricular wall, which swells into a bubble filled with blood. Discover the latest research on cardiac aneurysm here.
