Giant coronary aneurysm in a woman with Sjogren’s syndrome and rheumatoid arthritis history: case report

[email protected] Introduction Coronary artery aneurysm (CAA) is defined as a focal or diffuse dilatation of a coronary artery, greater than 1.5 times the diameter of normal adjacent segments. And the Committee of the American Heart Association has defined giant aneurysms as those >8 mm [1,2]. The incidence giant coronary artery aneurysm is hard to be determined, because few studies have been reported in literature. Other literature showed that the incidence of coronary artery aneurysm in the general population range from 0.02% to 0.04% and the incidence range from 1.1% to 5% in patients undergoing coronary angiopathy [3]. However the giant coronary aneurysms are rarely reported. The most affected coronary artery is the right coronary artery RCA, followed by the left anterior descending artery LAD and left circumflex ( LCX) [3,4].
