Incidental Finding of Vieussens' Collateral in Tricuspid Regurgitation Due to Infective Endocarditis.

ABSTRACT:

Background

This is an exceedingly rare case of an incidental finding of Vieussens' collateral with severe tricuspid regurgitation due to infective endocarditis.

Case summary

A 46-year-old male presented with dizziness, and a workup revealed infective endocarditis of the tricuspid valve with severe tricuspid regurgitation. Coronary angiography revealed a chronic total occlusion of the ostial right coronary artery (RCA), with well-developed collaterals from the left anterior descending artery to the RCA.
