Actual (reported)Mitral regurgitation (MR), also known as mitral insufficiency, is a condition in which the heart's mitral valve, located between two of the heart's main chambers, does not firmly shut, allowing blood to leak backwards within the heart. Improper functioning of the mitral valve disrupts the proper flow of blood through the body, resulting in shortness of breath and fatigue. When mild, MR may not pose a significant danger to a person's health, but severe MR may be associated with serious complications, such as heart failure, irregular heart rhythm, and high blood pressure. Although there are treatments for MR, including medication and surgery, more information is needed on the effectiveness of these treatments in people with significant MR. This study will compare the safety and effectiveness of corrective surgery added to optimal medical treatment (OMT) versus OMT alone in treating people with significant MR caused by an enlarged heart.

Participants will receive optimal medical therapy plus surgical mitral valve repair with complete annular ring placement
Participants will receive optimal medical therapy alone
Participants will receive optimal medical therapy plus 18-month delayed surgical mitral valve repair with complete annular ring placement
Participants will undergo open heart surgery to mechanically reduce mitral regurgitation (MR). A complete rigid or semi-rigid annular ring will be placed unless specifically contraindicated by intraoperative findings. The ring size will be between 24 mm and 27 mm in the anteroposterior diameter. Annular ring sutures will be placed circumferentially approximately 1 mm off the hinge point between the leaflet and the atrial tissue. The total number of sutures will vary between 4 and 7 sutures anteriorly, while 8 to 12 sutures will be utilized for the posterior segment of the annulus. Additional repair of the mitral apparatus itself will be based on intraoperative findings. Leaflet repair will be performed for significant prolapse. Submitral apparatus repair will be performed for ruptured or significantly elongated chordae as well as significant chordal tethering.
