Organic Tricuspid Regurgitation

It is usually reported that only 10–15% of patients with tricuspid regurgitation have an organic (primary) etiology of the valve disease. However, it is likely that the actual prevalence of organic etiology of tricuspid regurgitation has been underestimated because of the technical limitations of conventional two-dimensional echocardiography to visualize the anatomy and assess the function of the tricuspid valve. However, the correct diagnosis of tricuspid regurgitation etiology and the assessment of valve anatomy are pivotal either to plan surgery or to select the most appropriate device and approach in interventional cardiology in patients who need tricuspid valve repair.
