Summary

The mitral valve is the inflow valve into the main pumping chamber of the heart. It can become leaky or narrow, and cause blood to back up into the blood vessels of the lungs. When patients get symptoms from a leaky or narrow mitral valve, surgery is recommended to either fix or replace the valve. Many patients with mitral valve disease also develop a leaky tricuspid valve - the tricuspid valve is the inflow valve to the right side of the heart (the right heart pumps blood across the lungs). The amount of leakiness of the tricuspid valve is determined by an ultrasound test, and the amount of leakiness is graded as: none, mild, moderate, or severe. When a heart surgeon operates on a patient with a diseased mitral valve, he or she will fix the tricuspid valve if the tricuspid leakage is severe. This involves sewing a cloth-covered ring around the valve and narrowing it. If the tricuspid valve leakage is only mild (or absent), the surgeon will leave the tricuspid valve alone at the time of mitral valve surgery. If the tricuspid valve has moderate leakage surgeons are uncertain about what to do. In a recent review of thousands of patients across the nation having mitral valve surgery with moderately leaky tricuspid valves, 35 % of patients had tricuspid valve repair. Since the investigators don't know what the best approach is: to leave the moderately leaky tricuspid valve alone or to fix it with a cloth-covered ring, the investigators propose a study to determine which approach is best. Patients having mitral valve surgery with a moderately leaky tricuspid valve will be randomized to either 1. have a tricuspid valve repair or 2. to not have a tricuspid valve repair. The investigators will carefully follow these patients for two years and see if heart function is better among those who got their valve fixed.
