Mechanical versus biological aortic valve replacement strategies. [PDF]

, 2016
Aortic valve replacement (AVR) is the most frequently performed procedure in valve surgery. The controversy about the optimal choice of the prosthetic valve is as old as the technique itself. Currently there is no perfect valve substitute available.

Smart Antibacterial Coatings: Harnessing Bacterial Redox Activity for Infection Control

Advanced Materials Interfaces, EarlyView.
In this study, we have shown that ceftazidime‐loaded poly(3,4‐ethylenedioxythiophene) (PEDOT@CAZ) functions as a smart, redox‐responsive antibacterial coating that couples bacterial electrical activity with localized antibiotic delivery. Shewanella oneidensis and Pseudomonas aeruginosa induced distinct redox responses in PEDOT, reflecting their ...

Transvalvular mitral regurgitation following mitral valve replacement a diagnostic dilemma

Annals of Cardiac Anaesthesia, 2015
After mitral valve replacement with a prosthetic valve, the valve should be competent and there should not be any residual prosthetic valve regurgitation. Transvalvular residual prosthetic valve regurgitation are difficult to diagnose and quantify.

Percutaneous aortic valve replacement for severe aortic regurgitation in degenerated bioprosthesis: the first valve in valve procedure using the Corevalve Revalving system

, 2007
Percutaneous valve replacement for severe aortic stenosis has shown to be an alternative treatment option for non-surgical candidates. We report on the first successful valve in valve procedure in an 80-year-old patient with a severe regurgitation of a ...

Risk of acute kidney injury in patients with severe aortic valve stenosis undergoing transcatheter valve replacement [PDF]

, 2009
BACKGROUND: Transcatheter aortic valve implantation (TAVI) for high-risk and inoperable patients with severe aortic stenosis is an emerging procedure in cardiovascular medicine. Little is known of the impact of TAVI on renal function.
