Butterfly technique in mitral valve repair.

Area of Science:

• Cardiovascular Surgery
• Cardiac Valve Repair
• Mitral Valve Disease

Background:

• Degenerative mitral regurgitation often involves posterior leaflet prolapse with excess tissue.
• Current techniques may not precisely control leaflet height or can lead to annular issues.

Purpose of the Study:

• To evaluate the safety and efficacy of the butterfly technique for focal resection in posterior leaflet prolapse.
• To assess the technique's ability to control leaflet height without annular plication or systolic anterior motion.

Main Methods:

• The butterfly technique involves focal resection of redundant mitral valve tissue.
• Intraoperative measurements and ink dot marking guide precise leaflet height control.
• Indicated for posterior leaflets with prolapse height exceeding 20 mm.

Main Results:

• The butterfly technique allows precise control of leaflet height.
• It effectively addresses tissue redundancy in high posterior leaflet prolapse.
• The procedure was safely performed in most cases without increased risk of systolic anterior motion.

Conclusions:

• The butterfly technique is a safe and effective method for managing high posterior leaflet prolapse.
• It offers precise leaflet height control, avoiding annular plication and systolic anterior motion.
• This technique is a valuable option for specific degenerative mitral regurgitation cases.
