Experiences with the Repair of the Mitral Valve in Mitral Incompetence

Surgical repair of chordae tendineae rupture after degenerative valvular regurgitation using standardized bovine pericardium

“…The chordae implantation technique is similar to that described by us in case of partial transfer of the tricuspid valve (posterior leaflet, usually) to the mitral valve [6]. In this study, in all patients was performed annuloplasty using rigid open Gregori-Braile ring [12], preceeded in both cases, of Wooler annuloplasty [13], along the posteromedial commissure. Clinical improvement was observed in surviving patients, both with respect to functional class (16 of them in functional class I and one in functional class II) and the excellent auscultation of mitral valve (15 with no murmurs and two with discrete systolic murmur in the mitral focus, one of them associated with a diastolic murmur at the apex).…”

“…In association, in two (91%) cases, was performed plicature of the mitral annulus near the posteromedial commissure using technique by Wooler et al [13]. This is a hemi-ellipse prosthesis industrialized and commercially available (Braile Biomédica, São José do Rio Preto, SP, Brazil).…”

“…The two thresholds which correspond to the ends of the prosthesis are applied to the mitral annulus, at the height of the commissures of the projection, so that after the fixation of the prosthesis, the posterior leaflets moves to the anterior, and what is important, the posteromedial portion moves more sharply in the anterior-lateral directon, thus correcting existing dilation. In two (9.1%) patients, annuloplasty was performed according Wooler et al [13] to correct the excessive dilation of the posterior annulus of the mitral valve near the posteromedial commissure.

Durability of Mitral Valve Repair Performed Before the Age of 5 Years

“…Also, by mobilizing the posterior leaflet to the commissural portion using the suture, the leaflet can be stretched and brought towards the anterior leaflet. 7 This technique may be used as an adjunct to others, targeting the leaflet or subvalvular apparatus. The commissural annuloplasty technique may aid in reducing the tension on the valve components, and thus in part generate a similar effect as an artificial ring.…”

Resultado clínico tardio da anuloplastia mitral sem suporte em crianças e adolescentes

“…(14)) é um método que visa ao encurtamento da cúspide mural, a qual será fixada junto às comissuras por suturas ancoradas em feltros de Teflon. A diferença da técnica de Kay reside apenas quanto ao tipo de sutura e o ancoramento da mesma para prevenir desgarramento posterior.…”
