Abstract

A method of reversible suture snaring is described for evaluating the final valve seating and positioning before knot tying of valve sutures. This allows for alteration of the operative plan before investing substantial ischemic time in a nonfunctional result. The procedure has been used in 577 consecutive prosthetic valve replacements in the past 5 years. The technique maintains proper seating while the valve is permanently anchored in place.

Mitral valve repair.

Diseases that affect the mitral valve include mitral regurgitation, mitral stenosis, rheumatic heart disease, and cardiomyopathy. The results of diagnostic procedures are used to identify and confirm mitral valve disease, evaluate the patient's anatomy, and determine the severity of the disease. After the patient is prepared for surgery, the surgeon performs an intraoperative transesophageal echocardiogram and the patient is placed on cardiopulmonary bypass. A repair procedure (eg, annuloplasty, slidingplasty, chordal repair/transfer/replacement, valve replacement) is performed depending on the patient's specific anatomical abnormalities.

Meta-analysis of clinical outcomes following surgical mitral valve repair or replacement.

Although the use of mitral valve surgery has been successful at alleviating mitral valve disease, published studies on either replacement or repair have yielded mixed clinical outcomes regarding differences between repair and replacement. Meta-analysis of various outcomes from 29 published studies was conducted. Studies were separated into four groups by etiology of disease: ischemic; degenerative/myxomatous; rheumatic and mixed. The summary odds ratio for early mortality, comparing replacement to repair, was 2.24 (1.78-2.80), while the summary total survival hazard ratio was 1.58 (1.41-1.78), replacement compared to repair, indicating worse outcomes among those undergoing mitral valve replacement. The risk of thromboembolism was lower in the repair group (summary hazard ratio=1.86, replacement vs. repair), while there was no statistical difference in time to re-operation between the two treatment groups (hazard ratio=0.88 [95% confidence interval: 0.48, 1.62]). Analysis stratified by etiologic classification was able to detect strong evidence of differences in 30-day and total survival outcomes favoring repair for three disease groups (rheumatic, mixed and degenerative). Surgery for ischemic mitral valve had lower 30-day mortality for repair than replacement, but no statistically significant difference in the overall survival was detected. The reported information in the published studies used in the current work lacks sufficient detail to allow summary determination of outcomes by mitral valve repair techniques and by type of mitral valve replacement.
