A multimodality approach to a rare case of ruptured sinus of Valsalva aneurysm with tricuspid valve involvement: a case report.

ABSTRACT:

Background

Ruptured sinus of Valsalva aneurysm is a rare disease entity that is potentially life-threatening if left untreated. While imaging is the mainstay of diagnosis, resultant tricuspid valve involvement may mask typical findings providing a diagnostic challenge. Disruption of the tricuspid valve during ruptured sinus of Valsalva aneurysm with consequent tricuspid regurgitation is rare and infrequently described in the literature. Description of the utility and limitations of multimodality imaging in this scenario is equally scarce.

Case summary

We review the case of a young patient presenting with acute ruptured sinus of Valsalva aneurysm and involvement of the tricuspid valve on a background of severe aortic regurgitation requiring multimodality imaging for diagnostic and pre-surgical assessment.

Discussion

In young patients presenting with acute decompensation and pre-existing bicuspid aortic valve regurgitation, an increased clinical suspicion of a sinus of Valsalva aneurysm rupture is imperative. Doppler and 3D transoesophageal echocardiographic assessment should be pursued to characterize abnormal flows and clarify aetiology in the context of tricuspid involvement and resultant tricuspid regurgitation. A large-volume left-right shunt in proximity to the tricuspid annulus may result in disproportionately severe tricuspid regurgitation in the absence of annular disruption due to forced systolic opening of the leaflets by shunt flow and 'windsock' prolapse. Multimodality imaging can be essential in these cases to adequately assess the extent of the ruptured sinus of Valsalva aneurysm and overcome limitations of single modality imaging.
