Noncoronary aortic cusp rupture in an adult patient with ventricular septal defect: echocardiographic diagnosis

Pediatr Cardiol. 2011 Apr;32(4):527-9. doi: 10.1007/s00246-011-9904-0. Epub 2011 Feb 17.


Aortic 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 cusp perforation. We describe a case of subacute and severe aortic regurgitation due to noncoronary cusp prolapse resulting in the development of a large aneurysm and rupture of the noncoronary sinus of Valsalva into the right atrium.
