A Case of Rheumatic Tricuspid Stenosis 22 Years after Initial Mitral Valve Replacement / 日本心臓血管外科学会雑誌

ABSTRACT

Rheumatic tricuspid stenosis has become rare recently. A 54-year-old woman had undergone mitral valve replacement with a Carpentier-Edwards bioprosthesis for mitral stenosis 22 years previously and had undergone repeat mitral valve replacement for prosthetic valve failure 10 years later. She was admitted with severe leg edema. Cardiac catheterization revealed pulmonary hypertension and tricuspid stenosis with a diastolic pressure gradient of 6mmHg across the tricuspid valve. Tricuspid valve replacement was performed with a Hancock bioprosthesis. The postoperative course was uneventful and her edema improved markedly. This case suggested that careful follow-up to detect progression of tricuspid stenosis is necessary in patients with rheumatic valve disease and pulmonary hypertension.
