October 8, 2014
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

WASHINGTON D.C. -- September 16, 2014 -- Use of a dual-filter cerebral protection system reduces the number and volume of cerebral lesions in patients with severe aortic stenosis undergoing transaortic valve replacement (TAVR), according to prospective research presented at the 2014 Transcatheter Cardiovascular Therapeutics meeting (TCT).

In this manuscript, the authors describe their findings of a cohort analysis of 66 453 Medicare beneficiaries over the age of 65, who underwent aortic valve replacement (AVR) ± CABG and compare date of surgery, 30-day and one-year mortality between those receiving biological and mechanical prosthesis.

OBJECTIVES Biological valves are the most commonly implanted prostheses for aortic valve replacement (AVR) surgery in the UK. The aim of this study was to compare performance of porcine and bovinepericardial valves implanted in AVR surgery with respect to survival and reintervention-free survival in a retrospective observational study.

This study summarized data regarding valve use in over 1l,000 pts in the STS database who underwent aortic valve replacement for active endocarditis. Nearly 75% of pts had no prior cardiac surgery. Prior cardiac surgery was associated with a higher risk of root replacement (29.9% vs 7.2%), a higher rate of complications (68% vs 61%), and a substant
