Abstract
Aneurysmal coronary artery disease is defined as aneurysmal dilatations > 1.5 times the normal coronary segment. CAA is diagnosed in 0.3% to 4% of patients undergoing coronary angiography. CAA may be of congenital or acquired origin: atherosclerosis, accounting for 50% of cases, while 20-30% are congenital and 10-20% are inflammatory, other causes are abnormal connective tissue synthesis, infectious, tumor (rare) and trauma (iatrogenic). The pathogenesis of CAA involves underlying destruction of the vessel media. This thinning of media together with increased wall stress causes progressive dilatation of the segment of coronary artery. CAA may be detected in absence of symptoms; however, patients sometimes present with angina, myocardial infarction, or sudden death. CAA can be detected non-invasively using echocardiography, CTand MRI However, definitive diagnosis with coronary arteriography is usually needed. CAA that present with life threatening complications require prompt surgical intervention, the benefits, if any, of antiplatelets or anticoagulation therapies are unknown, the indications for myocardial revascularization in CAE are similar to those in other patients with atherosclerotic CAD. ” The aim of this study is to : -Verify the coronary artery ectasia. -Determine performance characteristics of coronary angiography for diagnosing coronary artery ectasia.
