Functional and Degenerative Mitral Regurgitation: One Ring Fits All?
Thorac Cardiovasc Surg
September 2020
Background: Three-dimensional saddle-shaped annuloplasty rings have been shown to create a larger surface of leaflet coaptation in mitral valve repair (MVR) for functional mitral regurgitation (FMR) and degenerative mitral regurgitation (DMR) which may increase repair durability. For the first time, this study reports mid-term results after MVR for DMR and FMR using a rigid three-dimensional ring (Profile 3D, Medtronic).
Methods: Between June 2009 and June 2012, 369 patients with DMR ( = 326) or FMR ( = 43) underwent MVR (mean age 62.
Background: Functional tricuspid regurgitation (FTR) secondary to left-sided heart disease may lead to poor quality of life and reduced long-term survival. This study evaluated clinical and functional outcomes of patients undergoing tricuspid valve (TV) repair using a rigid three-dimensional ring (Contour 3D, Medtronic) concomitant with another procedure.
Methods: From September 2011 to July 2015, 112 patients (mean age 70.
Article Synopsis
- The study aimed to assess the long-term performance of the St. Jude Medical Biocor porcine stented bioprosthesis in patients who underwent aortic valve replacement; it involved 455 patients at the German Heart Center Munich from 1985 to 1996.
- The results indicated a 10-year survival rate of 43.3% and a 15-year survival rate of 19.2%, with high freedom from structural valve deterioration (92.1% at 10 years) and low rates of reoperation due to valve-related issues.
- Overall, the research highlights the durability and reliability of the St. Jude Medical Biocor prosthesis over an extended follow-up period, showcasing
Background And Aim Of The Study: A total of 639 patients (479 men, 160 women; mean age 60 +/- 10 years) underwent isolated aortic valve replacement (AVR) between 25 November 1999 and 20 October 2003, using the Medtronic ADVANTAGE bileaflet mechanical heart valve. The study aim was to quantify the clinical performance of a valve with two design modifications: (i) an enlarged central orifice intended to improve blood flow characteristics; and (ii) an asymmetric butterfly pivot recess with expanded outflow component designed to enhance the washing of blood flow through the pivot region.
Methods: Patients were enrolled at 21 centers located in Europe, Canada, Australia, and the USA.
