New insights of tricuspid regurgitation: a large-scale prospective cohort study

Aims To evaluate the burden of tricuspid regurgitation (TR) in a large cohort, determine the right ventricle involvement of patients with TR and determine the characteristics of isolated TR. Methods and results Prospective study where consecutive patients undergoing an echocardiographic study in 10 centres were included. All studies with significant TR (at least moderate) were selected. We considered that patients with one of pulmonary systolic hypertension >50 mmHg, left ventricular ejection fraction Conclusion Significant TR is a prevalent condition and a high proportion of these patients have an indication for valve intervention. More than a half of patients with severe, massive, or torrential TR had a high surgical risk. Massive/torrential TR may have implications regarding selection and monitoring patients for percutaneous treatment.
