Coronary Artery Ectasia: Review
Dr. Muhsin TÜRKMEN, aDr. Atila BİTİGEN, aDr. Ali Metin ESENa
aKoşuyolu Kalp Eğitim ve Araştırma Hastanesi, İSTANBUL Coronary artery ectasia are defined as the dilation of a segment of a coronary artery at least 1.5 times the adjacent segment. Coronary artery ectasia and aneurysms are encountered in 0.3-5.3% of coronary angiographies. Ectasia affect most frequently the right coronary artery followed by circumflex artery and left anterior descending artery. The etiologic cause is atherosclerosis in 50% of patients, congenital in 20-30% and inflammatory or connective tissue disorder in 10 to 20%. Coronary artery ectasia is often accompanied by coronary artery disease (CAD) but can also be isolated. In patients with coronary ectasia, myocardial perfusion defects can be observed along the related artery region. Turbulent flow in the dilated segment, loss of axial flow leading to red blood cell aggregates and increased thrombogeneity in the same segment and the subsequent distal embolization of thrombi are significant contributors to microvascular perfusion defects.Keywords: Coronary vessels, dilatation, pathologic, coronary arteriosclerosisTurkiye Klinikleri J Med Sci 2006, 26:68-72
