Background: The Maze procedure is the surgical treatment that can alleviate the three complications of atrial fibrillation- tachycardia, thrombo-embolism and hemodynamic compromise. We attempted ablation of atrial fibrillation with monopolar eletrocautery.Our objective was to evaluate the results of surgical treatment of atrial fibrillation by ablation of the left atrial wallaround the pulmonary veins with conventional electrocautery during mitral valve replacement.Methods:This retrospective observational study was carried out in the Department of Cardiac Surgery, National Institute of cardiovascular diseases, Dhaka, Bangladesh,from January 2014 to February 2016. Ablation of AF with monopolar electrocautery was done during mitral valve replacement. Recurrence of atrial fibrillation, any new arrhythmia, complete heart block, bleeding and perforation was noted during the operation and in postoperative period. Patients were followed up upto three months after the surgery.Results: All the Patients were free from atrial fibrillation after the procedure. At discharge 100 %, after I month 96.2% and after 3 months 92.3 % patient were free from atrial fibrillation. No patients developed complete heart block requiring pace maker and there was no incidence of atrial perforation at the sites of ablation.Conclusion: The surgical treatment of the atrial fibrillation with elcetrocautery during mitral valve replacement is able to reverse this arrhythmia in a significant number of patients during short term follow-up without any complication.Cardiovasc. j. 2016; 9(1): 9-12

Abstract Background The mitral valve shows significant involvement in hypertrophic obstructive cardiomyopathy (HOCM). The mid-term outcomes of management of HOCM by prosthetic valve replacement with septal myectomy remain unclear. This study compared the prognosis of patients with and without prosthetic valve replacement. Methods From 01/2009 until 10/2015, 24 patients with HOCM underwent septal myectomy with or without valve repair/replacement were recruited. A total of 23 patients underwent echocardiographic evaluation before and after the operation. The follow-up duration ranged from 0.4 to 7 years (median 2.5 years). The Kaplan-Meier test was used to explore the association between prosthetic valve replacement and overall/disease-free survival among HOCM patients. Results A total of 9 patients underwent septal myectomy with/without mitral valve repair (MVr), and the other 15 patients underwent septal myectomy with mitral valve replacement (MVR). Six patients treated with MVR had unfavorable outcomes, including one peri-operative and three late deaths; one patient suffered from aborted sudden death, and one patient was treated for prosthetic valve endocarditis. Prosthetic valve replacement was associated with poor disease-free survival (p = 0.025). Conclusions Septal myectomy with or without-MVr was associated with a better outcome than septal myectomy with MVR in HOCM patients. The differences in prognosis were caused by more complicated left ventricular outflow tract structures and more prosthetic valve complications among patients undergoing MVR.

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.
