Evaluating the Benefit of Concurrent Tricuspid Valve Repair During Mitral Surgery

2016-02-07 18:30:37 | BioPortfolio


The purpose of the research is to determine whether repairing a tricuspid valve (TV) in patients with mild to moderate tricuspid regurgitation (TR), at the time of planned mitral valve surgery (MVS), would improve the heart health of those who receive it compared to those who do not.

At this point, the medical community is split in their opinion on whether surgeons should routinely repair mild to moderate TR in patients who are undergoing planned mitral valve surgery, and this study will answer this question.


The tricuspid valve controls the flow of blood in your heart between the right ventricle and the right atrium. TR is a condition where the valve does not close fully when it is supposed to and blood can then leak back into the right atrium. When TR becomes severe, surgery is usually performed to correct it. The purpose of the research is to determine whether repairing a tricuspid valve in patients with mild to moderate TR, at the time of planned mitral valve surgery, would improve the heart health of those who receive it compared to those who do not. There are no new or "experimental" procedures being tested in this study: both the mitral valve procedure and the tricuspid valve repair procedure are well established surgeries and are regularly performed together in patients who have severe TR. The available evidence addressing this issue is not definite: it is based on less rigorous methods of investigation, and the results have been conflicting. The study being proposed here will use rigorous scientific methods and should result in a very high level of certainty about what surgical treatment is best for patients with your condition.

This study will enroll people scheduled for mitral valve surgery with mild to moderate tricuspid regurgitation.

Medical and Biotech [MESH] Definitions

Abnormal protrusion of one or more of the leaflets of TRICUSPID VALVE into the RIGHT ATRIUM during SYSTOLE. This allows the backflow of blood into right atrium leading to TRICUSPID VALVE INSUFFICIENCY; SYSTOLIC MURMURS. Its most common cause is not primary valve abnormality but rather the dilation of the RIGHT VENTRICLE and the tricuspid annulus.

The pathologic narrowing of the orifice of the TRICUSPID VALVE. This hinders the emptying of RIGHT ATRIUM leading to elevated right atrial pressure and systemic venous congestion. Tricuspid valve stenosis is almost always due to RHEUMATIC FEVER.

Cardiac manifestation of gastrointestinal CARCINOID TUMOR that metastasizes to the liver. Substances secreted by the tumor cells, including SEROTONIN, promote fibrous plaque formation in ENDOCARDIUM and its underlying layers. These deposits cause distortion of the TRICUSPID VALVE and the PULMONARY VALVE eventually leading to STENOSIS and valve regurgitation.

Backflow of blood from the RIGHT VENTRICLE into the RIGHT ATRIUM due to imperfect closure of the TRICUSPID VALVE.

A species of gram-negative bacteria producing mild to severe ANAPLASMOSIS in SHEEP and GOATS, and mild or inapparent infections in DEER and CATTLE.
