NCT05595226

Brief Summary

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.

Outcome Measures

Primary Outcomes (1)

  • Composite events of mitral valve repair failure and 1-year reoccurrence of mitral regurgitation

    mitral valve repair failure, 1-year reoccurrence of mitral regurgitation

    1 year

Secondary Outcomes (4)

  • Individual occurrence of composite endpoints of mitral valve repair failure and 1-year reoccurrence of mitral regurgitation

    1 year

  • The incidence of secondary transfer, perioperative complications

    1 year

  • Intraoperative conditions including extracorporeal circulation time, aortic occlusion time

    1 year

  • The recurrence rate of residual mitral valve regurgitation

    1 year

Study Arms (2)

RT3D-TEE-guided mitral valve repair

EXPERIMENTAL

Two experienced surgeons and two experienced echocardiography technicians jointly formulated the plan for the TEE-guided mitral valve repair.

Procedure: RT3D-TEE-guided mitral valve repair

Control

NO INTERVENTION

Interventions

RT3D-TEE forms a surgical plan before surgery and 3 to 4 senior doctors with more than 50 cases of mitral valve repair perform the procedure.
