Isolated Tricuspid Stenosis

A case is reported of isolated tricuspid stenosis with a 5-year hemodynamic follow-up after a tricuspid commissurotomy. Fusion of the commissures and chordae tendineae of the tricuspid valve was noted at surgery. There was a history of rheumatic fever, and 5 years after surgery mild mitral stenosis had developed. Seven previously reported cases of isolated tricuspid stenosis have been considered by some authors to be congenital in origin, and, therefore, isolated tricuspid stenosis of rheumatic origin is thought to be established for the first time.
