title: Unusual cause of rapidly progressive right-sided heart failure: aortic sinus of Valsalva aneurysm causing ball valve obstruction of the tricuspid valve.
abstract: A rare presentation with rapidly progressive right heart failure due to tricuspid inflow obstruction (simulating right-sided valvular heart disease) caused by a non-coronary cusp sinus of Valsalva aneurysm with small perforation is reported. The aneurysm was causing ball valve obstruction at the tricuspid valve, leading to dilated right atrium and back pressure changes which were relieved after successful aneurysectomy.
