Background: To evaluate the performance of Society of Thoracic Surgeons (STS) 2008 cardiac surgery risk scores for postoperative complications in Chinese patients undergoing single valve surgery at multicenter institutions.  Methods: From January 2009 through December 2012, 4493 consecutive patients older than 16 years who underwent single valve surgery at 4 cardiac surgical centers were collected and scored according to the STS 2008 risk scores. The final research population included the following isolated heart valve surgery types: aortic valve replacement, mitral valve replacement, and mitral valve repair. Calibration of the risk scores was assessed by the Hosmer–Lemeshow (H-L) test. Discrimination was tested by calculating the area under the receiver operating characteristic (ROC) curve.  Results: The observed incidence rate for cerebrovascular accident (CVA), renal failure (RF), prolonged ventilation (Vent), reoperation (Reop), prolonged postoperative length of stay (PLOS), and short postoperative LOS (SLOS) was 0.90%, 1.32%, 4.18%, 2.43%, 3.64%, and 1.65%, respectively. The predicted incidence rate for CVA, RF, Vent, Reop, PLOS, and SLOS was 0.76%, 1.55%, 4.94%, 6.69%, 3.92%, and 2.54%, respectively. The STS 2008 risk scores give an accurate calibration for individual postoperative risk in CVA, RF, Vent, and PLOS (Hosmer–Lemeshow: P = .052, P = .474, P = .468, and P = .712, respectively). The area under the ROC curve of the STS 2008 risk scores for the above 4 postoperative complications were 0.714, 0.724, 0.727%, and 0.713, respectively. Conclusion: The STS 2008 risk scores were suitable for major postoperative complications in patients undergoing single valve surgery, except for Reop and SLOS.

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

Abstract Introduction Infective endocarditis (IE) may require heart valve surgery. However, it is well-known that heart valve surgery itself and previous IE predispose to IE. Purpose To access the risk of recurrent IE compared with first-time IE following heart valve surgery. Methods Using Danish nationwide registries, patients undergoing left-sided heart valve surgery (i.e. valve replacement or repair) in the course of a first-time IE hospitalization (1996–2017) were identified and matched with patients undergoing left-sided heart valve surgery due to another cause than IE in a 1:1 ratio. Patients were stratified according to type of surgical valve intervention and affected valve. The comparative risk of IE was assessed by cumulative incidence curves and multivariable Cox regression analyses. Results The study population comprised 975 patients with a first-time admission for left-sided IE requiring heart valve surgery (median age, 64.3 years [interquartile range 55.7–72.1], 77.6% men) matched with 975 controls undergoing left-sided heart valve surgery due to other causes than IE. The risk of recurrent IE was significantly higher than the risk of first-time IE following heart valve surgery (5.5% and 3.1% by 10 years, hazard ratio (HR) 1.72, 95% confidence interval (CI) 1.07–2.78) (Figure 1). The risk of IE recurrence was not significantly different in patients with IE undergoing valve replacement versus valve repair (5.6% and 5.4% respectively, HR 1.76, 95% CI 0.79–3.05). Likewise, the risk of IE recurrence was not significantly different for mitral versus aortic valve patients (3.5% and 6.3%, respectively, HR 0.73, 95% CI 0.36–1.48). Yet, the risk of IE recurrence was significantly higher among IE patients with biological versus mechanical prostheses (6.4% and 4.6%, respectively, HR 2.20, 95% CI 1.13–4.31). Figure 1: Cumulative incidences Conclusion Following left-sided heart valve surgery, the associated risk of recurrent IE was significantly higher than the risk of first-time IE.
