A rare case of left coronary sinus Valsalva aneurysm in a woman

Sinus Valsalva aneurysms (SVAs) are rare cardiac malformations observed in 0.09% of autopsies. SVAs are often diagnosed during evaluation of associated cardiac abnormalities requiring surgery, and the incidence is up to 1.5% in surgical series. The pathognomonic histologic finding is lack of continuity between the annulus fibrosus and the muscular and elastic aortic media. SVA formation is associated with perimembranous ventricular septal defect, bicuspid aortic valve, aortic regurgitation, and coarctation of the aorta. SVAs originate from the right coronary sinus in 70% of patients, the noncoronary sinus in 25% of patients, and the left coronary sinus in only 5% of patients, and themale to female ratio is 4:1. SVAs are usually clinically silent and detected by routine 2-dimensional echocardiography.
