Abstract
In this study, the diagnosis of MAC by TTE was made from January 2006 to January 2007 in female patients over the age of 60 years. Of these, 50 patients underwent coronary angiography for various reasons and formed the study group. These patients were compared to 50 age-matched patients without MAC who underwent coronary angiography for the same reasons during the same period and these patients formed the control group.
Comparison between the two groups of patients with special emphasis on age, risk factors, echocardiographic and angiographic findings. There was no significant difference in age, risk factors, electrocardiographic, echocardiographic and reasons for coronary angiography between patients with and without MAC. The main finding of our study was that mitral annular calcification is independent predictors of the presence of severe stenosis (≥ 70% diameter stenosis) in at least one major epicardial coronary artery on angiography between the two groups of patients. The study group had significantly higher rates of severe obstructive CAD as 3-vessel disease and left main CAD but similar rates of single vessel disease and 2-vessel disease .
