Long-term follow-up of posterior mitral leaflet extension for Type IIIb ischemic mitral regurgitation
Objective
Ischemic mitral regurgitation (MR) is generally associated with very poor outcomes and disappointing results, despite a seemingly perfect initial repair and optimal revascularization. We previously published our intermediate-term results of posterior leaflet augmentation without follow-up extending beyond 4 years. Our objective is to assess long-term durability of the repair, survival, and the causes of late mortality.
Methods
Ninety-one patients with severe (4+) Carpentier Type IIIb ischemic MR underwent repair in a single center between 2003 and 2022 by method of posterior leaflet extension using a patch of bovine pericardium and a true-sized remodeling annuloplasty ring, with or without surgical revascularization. Serial echocardiography was performed over the years to ascertain valve competence and degree of ventricular remodeling, in addition to telephone follow-up and chart reviews.
Results
The average age of patients was 67 ± 9.6 years. Mean follow-up was 8 ± 5 years with some extending to almost 20 years. One-, 5-, and 10-year freedom from recurrent significant MR, characterized as moderate or severe MR, was 98.6%, 85.5%, and 71.3%, respectively. Thirty-day mortality was 6.5%. One-, 5-, and 10-year survival was 85.5%, 64.4%, and 43.3%, respectively. Of all the mortalities, only 17.5% were proven to be directly cardiac related.
Conclusions
The suggested repair technique offers satisfactory long-term outcomes with minimal residual regurgitation in surviving patients when used in context of ischemic MR. Despite durable repair, we have discovered that poor long-term survival is not directly related to cardiovascular causes.
