Purpose : Repair of mitral valve stenosis is a challengeable part in technical view. We show stripping of fibrous tissue, commissurotomy, and ring annuloplasty in the thickened leaflets in a video.
Methods : In a woman patient of 44 years of age (body surface area 1.45 m2), we performed mitral valve repair. Preoperative hemodynamics included mitral valve area of 1.0 cm2, mean valve pressure gradient of 10 mmHg, and pulmonary artery pressure of 21 mm Hg in transthoracic echocardiography. She had preoperative exertional dyspnea and paroxysmal atrial fibrillation. Surgery was planned mitral valve repair with Cox-maze procedure and left atrial appendage closure.
Results : Becuase the patient had intact chordae, posterior leaflet augmentation was not required. Postoperatively, echocardiography showed a mitral valve area of 2.0 cm2, a mean pressure gradient of 3 mmHg, and a pulmonary artery pressure of 17 mmHg.
Conclusion : If mitral stenosis patients have nearly intact chordae, mitral valve repair can always be possible with stripping of fibrous tissue in thickened leaflet, commissurotomy, posterior leaflet augmentation if necessary, and an annuloplasty.
