Mitral Valve Replacement with Half-and-Half Technique for Recurrent Mitral Paravalvular Leakage

Area of Science:

• Cardiovascular Surgery
• Cardiac Valve Repair
• Medical Device Technology

Background:

• Recurrent paravalvular leakage (PVL) poses a significant challenge after mitral valve replacement (MVR).
• Previous MVRs can lead to severe mitral annular damage, increasing the risk of recurrent PVL.
• The half-and-half technique has been previously described for mitral annular calcification.

Observation:

• A 78-year-old male with three prior MVRs presented with recurrent PVL.
• The patient experienced hemolytic anemia and congestive heart failure due to PVL.
• Intraoperative findings revealed broad dehiscence at the anterior and posterior commissures of the mitral annulus.

Findings:

• A fourth MVR was successfully performed using the half-and-half technique.
• This technique involved specific suturing methods for the anterior and posterior annulus.
• Reinforcement with a bovine pericardial patch was necessary for extensive annular defects.

Implications:

• The half-and-half technique may be a viable option for managing recurrent PVL.
• This surgical approach could improve outcomes in patients with complex mitral annular issues.
• Further studies are warranted to validate the efficacy of the half-and-half technique in recurrent PVL.
