More than minimally manipulated (MMM) allograft heart valves should be classified as high risk devices, requiring premarket approval including safety and efficacy studies, according to an FDA panel.

This study demonstrates the basic concepts and technique of robotic mitral valve replacement for valve pathologies that are not suitable for repair. Among this group of patients, robotic surgery is still feasible with some technical differences from a standard robotic mitral valve repair procedure.

The authors compare 3 groups of patients undergoing aortic root replacement for ascending aorta aneurysm: valve-sparing root replacement (VSRR, n = 178), Bentall procedure with biological conduit (n = 91) or mechanical conduit (n = 101). Patients with VSRR had the best 5-year survival and low incidence of bleeding complications.

This exiting paper describes current achievements and open questions on the way to the manufacturing of heart valves using 3D printing.

This study utilised data form the UK National Adult Cardiac Surgery Audit to compare re-intervention free survival between porcine and bovine pericardial aortic valves. All elective or urgent aortic valve replacements with or without coronary artery surgery between 2003 and 2013 were included with a median follow-up time of 3.6 years.

CHICAGO -- September 30, 3014 -- Among patients aged 50 to 69 years who underwent aortic valve replacement with bioprosthetic or mechanical prosthetic valves, there was no significant difference in 15-year survival or stroke, although patients in the bioprosthetic valve group had a greater likelihood of re-operation but a lower likelihood of major bl

The New York State database was used to perform a retrospective analysis of outcomes for isolated AVR comparing bioprosthetic to mechanical valves. Propensity matching was used to create 1001 patient pairs. Survival and stroke rates were similar between the groups at an average of 10.8 years follow-up. The cumulative incidence of reoperation was

This video contains a brief presentation on a patient with a previous failed mitral repair, and then a narrated operative video demonstrating the steps of the mitral valve replacement.
