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.

Abstract Background Valve repair is the treatment of choice for native mitral valve regurgitation. The feasibility of repair when the defect is caused by acute infective endocarditis (IE) is debated. This study aims to compare the outcome of repair and replacement procedures, to report the rate of repair in a single surgical center, and to review the literature on this topic. Results We retrospectively analyzed 108 patients with native mitral IE, potentially eligible for surgical repair. Of these 108, 90 (83%) underwent surgery, and 18 were treated conservatively. Among the 90 surgical patients, 57 (63%) underwent valve replacement and 33 valve repair (37%). The mean follow-up duration was 3 years. The two primary endpoints were mortality and freedom from recurrent endocarditis. Secondary endpoints were the post-operative incidence of major adverse events (hospitalization for any cause, pacemaker implantation, new onset of atrial fibrillation, sternal dehiscence), left ventricular systolic function (LVSF), and valvular function at 1-year echocardiographic follow-up. All-cause mortality was lower for valve repair, although not significantly (p = 0.86), as well as nonfatal adverse events (p = 0.92) and relapse rate (p = 0.20) at 3 years. We did not find differences between the two groups at echocardiographic follow-up, neither for left ventricular systolic function (p = 0.22), nor for valvular continence (p = 0.28). Conclusions In our experience, the mid-term outcome of repair in IE is comparable to valve replacement and should be considered whenever possible, as in degenerative valve disease. The review of the literature supports this strategy.

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.

Abstract Background This study aims to evaluate the early and mid-term outcomes of mitral valve repair for degenerative mitral regurgitation (MR) in patients with left ventricular systolic dysfunction. Methods From January 2005 to December 2016, the profiles of patients with degenerative MR who underwent mitral valve repair at our institution were analyzed. Left ventricular systolic dysfunction was defined as an ejection fraction < 60% or left ventricular end-systolic dimension > 40 mm. Finally, 322 patients with left ventricular systolic dysfunction were included in this study. The prognosis of left ventricular function during follow-up was evaluated and preoperative factors associated with deteriorated left ventricular systolic function during follow-up were analyzed. Results The in-hospital mortality rate was 1.6%. The rate of eight-year overall survival, freedom from reoperation for mitral valve and freedom from recurrent MR were 96.9, 91.2 and 73.4%, respectively. Intraoperative residual mild MR (hazard ratio 4.82) and an isolated anterior leaflet lesion (hazard ratio 2.48) were independent predictive factors for recurrent MR. During follow-up, 212 patients underwent echocardiography examinations at our institution. Among them, 132 patients had improved left ventricular systolic function, and 80 patients had deteriorated left ventricular systolic. Freedom from recurrent MR was found in 75.9% of the improved left ventricular systolic function group and 56.2% of the deteriorated left ventricular systolic function group (P = 0.047). An age > 50 years (odds ratio 2.40), ejection fraction≤52% (odds ratio 2.79) and left ventricular end-systolic dimension≥45 mm (odds ratio 2.31) were independent risk factors for deteriorated left ventricular systolic function during follow-up. Conclusions Mitral valve repair could be safely performed for degenerative MR in patients with left ventricular systolic dysfunction. Intraoperative residual mild MR and an isolated anterior leaflet lesion were independent predictive factors for recurrent MR. An age > 50 years, ejection fraction≤52% and left ventricular end-systolic dimension≥45 mm were independent risk factors for deteriorated left ventricular systolic function during follow-up.
