Isolated rheumatic tricuspid stenosis with reverse Lutembacher's physiology

Tricuspid valve dysfunction occurs frequently in, patients with rheumatic h eart disease and is usually manifested as functional or organic tricuspid r egurgitation. Rheumatic tricuspid stenosis is less common, and occurs chara cteristically in the presence of concomitant mitral valve disease. In this report, we describe the clinical and echocardiographic findings in a patien t with isolated rheumatic tricuspid stenosis and a right-to-left shunt acro ss the interatrial septum, likely as a result of a patent foramen ovale, re sulting in central cyanosis. This case illustrates an interesting associati on of tricuspid stenosis and an interatrial right-to-left shunt suggestive of a reverse Lutembacher's physiology.
