Effect of RT3D-TEE-guided Mitral Valve Repair on Outcomes in Patients With Degenerative Mitral Valve Disease

Effect of RT3D-TEE-guided Mitral Valve Repair on Outcomes in Patients With Degenerative Mitral Valve Disease

The aim of this randomized controlled trial to investigate the effects of Real-time 3D transesophageal echocardiography (RT3D-TEE)-guided mitral valve repair on surgical failure and 1-year reoccurrence of mitral valve regurgitation in patients with degenerative mitral value disease.

Inclusion Criteria:

• Diagnosed with chronic primary degenerative mitral regurgitation by the preoperative echocardiogram.
• Informed consent was obtained

Exclusion Criteria:

• Re-operation of mitral regurgitation
• Concurrent surgical plan for congenital heart disease, coronary artery bypass grafting, aortic valve surgery, radiofrequency ablation of atrial fibrillation and other cardiac surgeries.
• Mitral valve replacement
• Unable to undergo TEE
