464 Echocardiographic features of severe tricuspid regurgitation

Abstract

BackgroundThere is limited data on the conditions associated with severe native valve tricuspid regurgitation (TR). Our aim was to determine the etiologies and associations of severe TR from a diverse population of patients referred for echocardiography.MethodsWe identified all patients with severe TR in the echocardiogram database at Vancouver General Hospital between January 1, 2004 and Dec 31, 2011. The echocardiogram reports were reviewed to determine the etiology of TR and were classified as primary TR secondary to tricuspid leaflet pathology or functional TR related to right ventricular pressure and/or volume overload. In patients with functional TR, we identified the presence or absence of significant pulmonary hypertension (PAS P ≥ 50mmHg). In the absence of significant pulmonary hypertension, we also identified the conditions associated with functional TR.ResultsTabled 1ConclusionTricuspid valve pathology accounts for only 7.2% of all cases of severe TR . Pulmonary hypertension and left sided heart disease were the most common conditions associated with functional TR. Severe TR with no recognized cause was also noted in 10.8%. Further studies regarding the mechanism of idiopathic TR is required. BackgroundThere is limited data on the conditions associated with severe native valve tricuspid regurgitation (TR).
