Mitral valve repair (MVRp) is associated with better survival in patients with organic mitral regurgitation (MR) when compared to mitral valve replacement (MVR). However, there is an important controversy about the type of surgical treatment that should be used in patients with functional MR (FMR). The aim of this study was to compare MVRp (i.e. restrictive annuloplasty) and MVR in patients with FMR. Pre- and operative demographic and clinical data of 392 patients (64% of male, mean age: 65±10 years) with FMR who underwent mitral surgery between 1992 and 2007 were prospectively collected in a computerized database. MVRp was performed in 52% of patients (n=204) and MVR in 48% (n=188). Compared to patients undergoing MVRp, those with MVR were significantly more frequently symptomatic (77% vs. 59%, p=0.0002), had lower left ventricular ejection fraction (LVEF) (40±15%, vs. 46±15%, p=0.0003) and had higher prevalence of pulmonary hypertension (36% vs. 24%, p=0.01) preoperatively. However, there was no significant difference between the 2 groups with regards to age, gender, MR severity, diabetes, obesity, systemic hypertension and atrial fibrillation (p>0.3). Although operative mortality was significantly lower after MVRp compared to MVR (9% vs. 17%, p=0.02), long-term survival was not statistically different between procedures (6 years: 74±4% vs. 72±4%; 12 years: 54±5% vs. 52±7%; p=0.58). After adjusting for other risk factors, the type of procedure (MVRp vs. MVR) did not come out as an independent predictor of either operative (Odds-ratio=1.7, 95% confidence interval [CI]: 0.8 –3.8, p=0.15) or long-term mortality (Hazard-ratio [HR]=1.1, 95%CI: 0.9 –1.4, p=0.29). The independent predictors of long-term mortality were age (HR= 1.04, 95%CI: 1.01–1.07, p=0.003), NYHA class ≥III (HR=1.4, 95%CI: 1.1–2, p=0.02) and LVEF (HR=1.02, 95%CI: 1.01–1.04, p=0.0009). As opposed to what has been reported in patients with organic MR, there is no evidence that MVRp provides any benefit in terms of survival compared to MVR in patients with FMR. These findings suggest that MVRp is not an optimal surgical treatment for FMR and provide an impetus toward the development of new surgical approaches for these patients.

Repair Group

This study compares mitral valve repair and mitral valve replacement with chordal preservation for chronic mitral regurgitation due to myxomatous degeneration with special reference to left ventricular function. Twenty-six patients underwent complete preoperative and 2 years later postoperative echocardiography study. Thirteen patients underwent mitral valve replacement associated with preservation of chordae tendineae and papillary muscles, and 13 patients had mitral valve repair. There were no statistically significant differences between the 2 groups for clinical findings, hemodynamic profiles, or left ventricular function compared prior to surgery. After correcting mitral regurgitation, increase in cardiac index was significant for the repair group. Left ventricular end-diastolic volume decreased in both groups. Left ventricular end-systolic volume significantly decreased in the repair group, but remained unchanged in the replacement group. Both ejection fraction and mean left ventricular circumferential fiber shortening velocity (mVcf) decreased in the replacement group, but significantly increased in the repair group 2 years after surgery. These findings suggest valve replacement with chordal preservation shows less improvement in ventricular systolic function late after surgery compared with mitral valve repair.

The types of surgical correction of the mitral valve pathology, hospital and long-term results were studied. The mitral valve repair being compared to the mitral valve replacement is procedure of choice as it provides stable results. In the study we demonstrate that the long-term results of reconstructive procedures on the mitral valve have advantages over mitral valve replacement in terms of survival, freedom from reoperation and tromboembolc complications.

Actuarial Survival

Aim This retrospective study was undertaken to evaluate the long-term outcomes of mitral valve repair in rheumatic patients. Methods From 2003 to 2019, 151 patients (mean age 26.5 ± 14.9 years; 68.9% female) underwent mitral valve repair. Fifty-three (35.1%) had atrial fibrillation, and 79 (52.3%) were in New York Heart Association class III/IV. Pure mitral regurgitation was present in 109 (72.2%) patients, pure stenosis in 9 (6%), and mixed regurgitation and stenosis in 33. Results Three (2%) patients died postoperatively and 4 (2.6%) were lost during follow-up. Mean follow-up was 90.5 ± 55.6 months. There were 22 (14.8%) late deaths. Actuarial survival at 5, 10, and 15 years was 90.7% ± 2.5%, 83.5% ± 3.6%, and 76.5 ± 6.1%, respectively. Twelve (8.5%) patients underwent reoperation. Freedom from reoperation at 5, 10, and 15 years was 96.1% ± 1.7%, 89.8% ± 3.2%, and 82.3% ± 6.1%, respectively. Forty-two (29.2%) patients developed recurrent mitral regurgitation. Freedom from recurrence of mitral regurgitation at 5, 10, and 15 years was 70.9% ± 4.3%, 56% ± 5.9%, and 53.3% ± 6.4%, respectively. Eighty-one (56.6%) patients were and free from all events during follow-up. Freedom from all events at 5, 10, and 15 years was 64.8% ± 4.1%, 48.6% ± 5.3%, and 43.7% ± 5.8%, respectively. Conclusions Although rheumatic mitral valve repair is associated with late recurrence of mitral regurgitation, it has benefits in selected patients, especially children and young patients who want to avoid the lifelong risks of anticoagulation. Long-term follow-up is essential in these patients.
