Mitral Valve Surgery

Mitral Valve Surgery is a highly specialized cardiothoracic discipline focused on the repair or replacement of the mitral valve to restore efficient cardiac function and prevent progressive heart failure. As a critical subject presented at a global Surgery Conference, this session explores operative precision, minimally invasive techniques, and long-term functional outcomes in mitral valve repair surgery. Given the increasing prevalence of degenerative valve disease, rheumatic pathology, and ischemic regurgitation, timely surgical intervention plays a central role in preventing irreversible ventricular remodeling.

The mitral valve regulates blood flow between the left atrium and left ventricle. Dysfunction may result in regurgitation, stenosis, or combined pathology, leading to dyspnea, arrhythmia, fatigue, and eventual heart failure. Surgical decision-making depends on valve anatomy, ventricular function, and symptom severity. Whenever feasible, valve repair is preferred over replacement due to superior durability, preserved ventricular function, and reduced need for lifelong anticoagulation.

Mitral valve repair techniques include annuloplasty ring implantation, leaflet resection, chordal replacement using artificial neochordae, and commissurotomy for stenotic lesions. These approaches aim to restore normal leaflet coaptation and maintain physiologic valve motion. In cases where repair is not possible, valve replacement using mechanical or bioprosthetic valves is performed, with careful consideration of patient age, comorbidities, and anticoagulation tolerance.

Minimally invasive and robotic-assisted mitral procedures have significantly improved postoperative recovery and cosmetic outcomes. Smaller thoracic incisions, enhanced visualization, and refined instrumentation allow precise intracardiac reconstruction with reduced surgical trauma. Intraoperative transesophageal echocardiography provides real-time evaluation of repair adequacy before chest closure.

Postoperative management focuses on rhythm monitoring, anticoagulation when indicated, and surveillance for valve durability. Multidisciplinary collaboration among cardiologists, imaging specialists, anesthesiologists, and cardiac surgeons ensures optimized perioperative care and long-term follow-up. Emerging technologies, including transcatheter mitral interventions and artificial intelligence-assisted imaging, are expanding therapeutic possibilities for high-risk patients.

By integrating surgical expertise, advanced imaging guidance, and minimally invasive innovation, mitral valve surgery continues to improve survival, preserve ventricular function, and enhance quality of life for patients with structural heart disease.
