Aortic regurgitation caused by leaflet perforation is most frequently seen in association with infective endocarditis that involves the aortic valve. There have been occasional reports of iatrogenic aortic regurgitation caused by aortic valve injury after cardiac surgery with the use of the transaortic approach or invasive cardiac procedures. Suture-related aortic valve injury can develop during periaortic cardiac surgery, but this has been very rarely reported. Inadvertent injury to an aortic valve leaflet caused by a stitching needle or surgical forceps can produce leaflet perforation with aortic regurgitation. This report describes a case of aortic regurgitation that was caused by iatrogenic aortic valve leaflet perforation, and this occurred in a 22-year-old woman who underwent repair of a ventricular septal defect (VSD) 15 years previously. Transthoracic echocardiography (TTE) showed a defect located at the aortic annulus close to the infundibular septum on a two-dimensional echocardiographic study and we observed an eccentric jet flow into the left ventricle in early diastole on the continuous wave and color flow Doppler studies. A small perforation in the body of the right aortic cusp and mild to moderate aortic regurgitation were confirmed by the use of transesophageal echocardiography (TEE) and ascending aortography.

    Different surgical techniques for complete atrioventricular septal defect (CAVSD) repair have been described, with the double-patch technique being most frequently employed. More recently a newer technique using a modified single-patch repair has been advocated. We hypothesized that the modified...

    ortic regurgitation is a common complication of ventricular septal defects. The most common mechanism is right or noncoronary cusp prolapse. Other mechanisms are right or noncoronary cusp fibrosis resulting in thickening and restricted motion of the leaflets or infective endocarditis leading to...
