A Simplified Approach to Degenerative Disease: Triangular Resections of the Mitral Valve

Left ventricular performance early after repair for posterior mitral leaflet prolapse: Chordal replacement versus leaflet resection

“…In our study, a higher percentage of patients who underwent leaflet 8 resection received the Cosgrove ring as compared to those who underwent chordal replacement.9The effect of this difference on LV performance after surgery is unclear but warrants , it remains unclear whether significant LV mass regression proceeds 12 concurrently with the recovery of normal LV geometry after MV repair. Shafii et al showed that 13 LV mass regression, which occurred within the first postoperative year and persisted to 5 years, 14 was incomplete after MV surgery 32. Reverse LV remodeling early after MV repair is highly 15 compatible with the results of our study.…”

Chordal Reconstruction versus Leaflet Resection for Repair of Degenerative Posterior Mitral Leaflet Prolapse

“…Both techniques have been shown to produce excellent long-term results. 1,2,10,11) Leaflet resection leads to the loss of native leaflet tissue and alters the anatomic and physiologic function of the MV. This leads to an increase in leaflet stiffness resulting in restriction in leaflet mobility and reduced area of coaptation with the anterior mitral leaflet.…”

Mitral valve reconstruction: long-term results of triangular resection for degenerative prolapse

“…6 In fact, recent reports about triangular resection of the anterior leafl et have been more encouraging and suggest that it can be performed safely. [6][7][8] In our experience, the noreoperation rate at 10 years in patients receiving surgery on the anterior and posterior leafl ets was 92.3% ± 3.7% and 90.4% ± 5.3%, respectively. Thus, there was no signifi cant difference in the risk of reoperation, regardless of the site of prolapse.…”
