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.

Background: COR-KNOT® (LSI Solutions, New York, NY, USA) is an automated suture securing device has not been well known. We report a case series for first automated knotting device used for minimally invasive heart valve surgery in Bangladesh. Method and Results: To overcome the challenge of knot securing via a Key-Hole surgery we have used CORKNOT ®. The newest device is capable of remotely and automatically secure sutures and simultaneously can cut and remove the excess suture tails. We covered the spectrum of heart valve surgery: There was one case of bioprosthetic aortic valve replacement, one case of mitral valve repair, one case of bioprosthetic mitral valve replacement, one case of failed mitral valve repair with COR-KNOT® explantation followed by mechanical mitral valve replacement and one case of redo-mitral valve replacement. Average length of hospital stays was 5 ± 1days. There was one reopening, one post-operative atrial fibrillation. No wound infection and no 30day mortality. Conclusion: We conclude, COR-KNOT® is a safe and effective tool to reduce the duration of operation. Clinical outcome of heart valve surgery with COR-KNOT® is comparable with other methods of suture tying methods. Bangladesh Heart Journal 2019; 34(2) : 127-131

The favorable outcomes achieved with modern mitral valve repair techniques redefined the role of mitral valve replacement. Various international databases report a significant decrease in replacement procedures performed compared with repairs, and contemporary guidelines limit the application of surgical mitral valve replacement to pathology in which durable repair is unlikely to be achieved. The progressive paradigm shift toward endoscopic and robotic mitral valve surgery is also paralleled by rapid developments in transcatheter devices, which is progressively expanding from experimental approaches to becoming clinical reality. This article outlines the current role and future perspectives of contemporary surgical mitral valve replacement within the context of mitral valve repair and the dynamic evolution of exciting transcatheter alternatives.

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.

Objectives: To describe national trends in the incidence and outcomes of patients with chordae tendineae rupture (CTR).Methods: Patients who were diagnosed with CTR between 2000 and 2012 were identified in National (Nationwide) Inpatient Sample (NIS) registry. CTR was defined using validated International Classification of Diseases, 9th Edition, Clinical Modification diagnosis (ICD9-CM) codes. Results: A total of 37,287 (14,833 mitral valve repair, 7780 mitral valve replacement) CTR cases were identified. Overall, in-hospital mortality in CTR decreased by 3% from 2000 to 2012 (P < 0.001). From 2000 to 2012, the rate of mitral valve repair increased from 27.2% to 46.4%, (P < 0.001) with a concurrent decrease in the rate of mitral valve replacement (from 27.8 to 17.7%, P < 0.001). After multivariate adjustment, patient age (OR = 1.04, 95% CI 1.03-1.06, P < 0.001), congestive heart failure (CHF) (OR = 2.08, 95% CI 1.19-3.64, P = 0.01), myocardial infarction (MI) (OR = 3.58, 95% CI 2.10-6.11, P < 0.001), Deyo/Charlson comorbidity index (OR = 1.23, 95% CI 1.07-1.41, P < 0.003) and use of the intra aortic balloon pump (IABP) (OR = 4.81 95% CI 2.71-8.55, P < 0.001) were found to be independently associated with greater odds of mortality in these patients. Additionally, mitral valve replacement was significantly associated with higher costs of hospitalization (coefficient 15693, 95% CI 12638-18749, P < 0.001)Conclusion: Mitral valve repair is associated with reduced inpatient mortality and costs compared with mitral valve replacement. A substantial increase in the percentage of cases undergoing mitral valve repair with a concurrent decrease in cases undergoing mitral valve replacement were observed. Increasing age and comorbidity index, history of CHF and MI, and use of IABP were identified as factors that could increase the risk of mortality in patients with CTR.
