Concomitant tricuspid valve repair for mild-moderate tricuspid regurgitation patients undergoing mitral valve surgery? A meta-analysis and meta-regression
J Cardiovasc Surg (Torino). 2023 Jul 24. doi: 10.23736/S0021-9509.23.12760-1. Online ahead of print.ABSTRACTThe development of tricuspid regurgitation (TR) is a common complication of mitral valve disease. Although severe TR is usually operated on at the same time of mitral valve surgery (MVS), controversies remain regarding whether mild to moderate TR patients should be operated. Concomitant tricuspid valve repair with MVS for mild-moderate TR patients. Electronic databases were searched from inception to November 20, 2022 to include any observational or randomized controlled trials (RCT) that compare concomitant tricuspi...

Can Patent Foramen Ovales Cause Problems?
Discussion During fetal development, the heart primum and secundum septa grow and overlap leaving a small but important channel between the two atria. The foramen ovale is a flap valve moving blood from the right atrium into the left atrium directly and bypassing the high pressure pulmonary system. After birth and breathing air, the neonate’s lungs open up and the pulmonary vascular resistance decreases. The left atrium now has a relatively higher pressure than the right atria, and therefore pressure on the flap valve closes the foramen ovale. Usually within 6-12 months, the fusion of the primum and secundum of the f...

Preoperative higher right ventricular stroke work index increases the risk of de novo aortic insufficiency after continuous-flow left ventricular assist device implantation
This study investigated the influence of preoperative hemodynamic parameters on de novo AI in CF-LVAD recipients. We reviewed 125 patients who underwent CF-LVAD implantation without concomitant AV surgery between 2005 and 2018. De novo AI was defined as moderate or severe AI in those with none or trivial preoperative AI. During mean 30  ± 16 months of CF-LVAD support, de novo AI-free rate was 86% and 67% at 1 and 2 years, respectively. Multivariable analysis showed that higher right ventricular stroke work index (RVSWI) (hazard ratio, 1.12 /g/m2/beat; 95% confidence interval, 1.00 –1.20;p = 0.047) and trivial ...

Benchmarking Outcomes of Surgical Aortic Valve Replacement in Patients with Bicuspid Aortic Valves
CONCLUSIONS: In this nationally-representative study, 30-day mortality was similar but risk-adjusted 5-year mortality was significantly lower in bicuspid patients undergoing isolated SAVR compared to tricuspid patients, specifically low-risk and normal left ventricular ejection fraction patients. This analyses provides a much-needed 5-year longitudinal national-level benchmark to better inform the discussion of transcatheter vs SAVR in bicuspid patients.PMID:37454786 | DOI:10.1016/j.athoracsur.2023.06.026

Midterm outcomes of minimally invasive mitral valve surgery in a heterogeneous valve pathology cohort: respect or resect?
CONCLUSIONS: Despite a heterogeneous cohort with mixed valve pathologies, there is a high reconstruction rate, low short- and midterm morbidity, mortality and need for re-intervention with comparable outcomes of the resect and respect technique in a specialized MIV center.PMID:37426140 | PMC:PMC10323544 | DOI:10.21037/jtd-22-1796
