Abstract
Seven cases of isolated prolapse of the tricuspid valve were detected among 23,778 consecutive cross-sectional examinations. None of the 7 patients had mitral prolapse or other heart and/or lung diseases. The presence of tricuspid regurgitation was also documented by conventional and/or color Doppler in all patients. We found no relationship between échocardiographie findings of tricuspid prolapse and clinical symptoms. It can be deduced from our investigation that isolated tricuspid valve prolapse can be present without any associated cardiac or lung disease. Echocardiography is the appropriate technique for the identification and the evaluation of the wide spectrum of the anomaly. Finally, cross-sectional and Doppler echocardiography can play a role in detecting the potential evolution and/or complications of this valve disorder.
