Long-term results of triple valve repair in rheumatic heart disease.

BACKGROUND: The aim of this study is to analyze the clinical outcomes of triple valve repair for rheumatic heart disease in terms of both early results and long-term benefits. METHODS: Between January 2008 and December 2016, all the patients who underwent triple valve repair for rheumatic heart disease were included in this study. RESULTS: Thirty-eight patients underwent triple valve repair procedure for rheumatic heart disease at our institute. Mean age was 33 years; 60.5% were females. Techniques used to achieve mitral valve repair were: commisurotomy (n = 26), prosthetic ring annuloplasty (n = 9), posterior teflon annuloplasty (n = 23), leaflet shaving (n = 14), implantation of neochordae (n = 5) and pericardial patch augmentation of mitral valve leaflets (n = 6). For aortic valve repair, the techniques used were: commisurotomy (n = 23), leaflet shaving (n = 16), pericardial patch augmentation (n = 3), subcommisural plication (n = 10), free margin plication (n = 2) and free margin resuspension (n = 1). Tricuspid valve repair was performed using modified Devega's technique (n = 32), commisurotomy (n = 9) and posterior annular plication (bicuspidization) (n = 5). The operative mortality was 0%. There was no primary repair failure. Estimated survival at the end of 1 year, 5 years and 10 years was 100%, 91.6% and 65.8%, respectively. Overall freedom from reintervention at 1, 5 and 10 years was 100%, 96.4% and 61.4, respectively. CONCLUSION: Triple valve repair provided satisfactory early and long-term results in this challenging subset of patients and can be considered as an acceptable option for significant triple valve disease due to the absence of anticoagulation-related events.

Primary or secondary Bentall-De Bono procedure: are the outcomes worse?

BACKGROUND: The aim of this study was to compare the outcomes of a primary and secondary Bentall-De Bono procedure. METHODS: From 2008 to 2015 (8-year period), 308 patients underwent a Bentall-De Bono procedure in our institute. The mean age was 43 ± 13 years and 80% were men. Twenty-eight patients had prior cardiac surgery through a median sternotomy (group 1) and 280 underwent a primary Bentall-De Bono procedure (group 2). Various preoperative and perioperative parameters were analyzed before and after propensity-score matching. RESULTS: Before propensity-score matching, patients undergoing a secondary Bentall-De Bono procedure had a worse preoperative profile, as indicated by a higher EuroSCORE II ( p < 0.0001), with hospital mortality in group 1 of 14% (4/28) and 5% (14/280) in group 2 ( p = 0.069). After propensity-score matching, there was no significant difference in EuroSCORE II ( p = 0.922) or hospital mortality ( p = 0.729). After adjusting for the different variables, repeat sternotomy could not be identified as an independent predictor of postoperative mortality or morbidity. Survival at the end of 1 and 5 years in both groups showed no significant differences before or after propensity-score matching ( p = 0.328 and p = 0.356, respectively). In Cox multivariable regression analysis, reoperation was not identified as an independent factor for survival before ( p = 0.559) or after propensity-score matching ( p = 0.365). CONCLUSION: A secondary Bentall-De Bono procedure can be performed with acceptable mortality and morbidity, and with midterm survival rates comparable to those of a primary Bentall-De Bono procedure.

Single-stage repair for multiple muscular septal defects: a single-centre experience across 16 years.

OBJECTIVES: Multiple muscular ventricular septal defects (VSDs) are surgically challenging and its management remains controversial. We present a technique of surgical repair for muscular VSDs, which includes surgical exposure and detection of these defects and has excellent clinical outcomes. METHODS: We have analysed consecutive patients who underwent surgical repair of isolated multiple muscular VSDs under cardiopulmonary bypass over a 16-year period (from January 2001 to November 2016) in a single centre from the southern part of India. These defects were accessed through the right atrium in most cases and closed directly; completeness of closure was confirmed by pressurizing the left ventricle with blood cardioplegia. There were no haemodynamically significant residual VSDs following repair. RESULTS: One hundred and two patients with an average time of follow-up of 4.1 years (1 month-12 years) were included. The mean age of our patients at the time of operation was 23.5 months (3 months-22 years) with a mean weight of 7.9 kg (2-55 kg). The mean cardiopulmonary bypass and cross-clamp time was 118.8 ± 39.2 min (mean ± SD) and 76.5 ± 29.4 min (mean ± SD), respectively. There were 10 (9.8%) hospital deaths and 3 late deaths in the entire study group. Permanent pacemaker was implanted in 2 patients. Seventy patients could be followed up after discharge. Postoperative pulmonary artery pressure was normal in 52% of the patients, mild-to-moderate hypertension in 27% and severe in 7% of the patients. The ejection fraction was >60% among the survivors, and there were no reoperations or reinterventions. CONCLUSIONS: This surgical approach to multiple muscular VSDs is safe and effective with minimal risk of complete heart block and diminution of ventricular function.
