[Primary tricuspid valve insufficiency. Report of 2 clinical cases]

Two case reports of primary tricuspid regurgitation are presented which diagnoses were made in mean adult life after a long period of few symptoms. The clinical outcome of the two cases was uneven in the sense that only one of them could be corrected with single surgical procedures. Despite relatively rare, this pathology could probably be turned more frequent with a complete and systematic echocardiographic approach. In connection with the reported cases, a review is made of the main etiologies and of some published reports.
