Triple Björk-Shiley valve: More than 30 years of asymptomatic functioning: To the memory of late academic Prof. Isidor Papo and the 45th anniversary of the first valve implantation in Yugoslavia [PDF]

, 2010
Introduction. The Björk-Shiley Delrin (BSD) tilting disc heart valve was first clinically used in 1969. A triple BSD valve replacement has not been quite common, because of high postoperative risk and complications, but there have been several cases with

Predicting Coronary Occlusion Risk during Redo‐TAVR at First TAVR: Asymmetric Calcification Causes Failure

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background and Aims Predicting coronary artery occlusion due to sinus sequestration (SS) during a second transcatheter aortic valve (TAV) procedure using pre‐procedural computed tomography (CT) after the first TAV replacement (TAVR) is underreported.

Long‐Term Impact of Prosthesis‐Patient Mismatch After Transcatheter Aortic Valve Replacement in Patients With Small Aortic Annuli

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background Prosthesis‐patient mismatch (PPM) remains common following transcatheter aortic valve replacement (TAVR) and is associated with worse clinical outcomes. PPM is of particular concern in small aortic annuli (SAA). Aims To compare the incidence, predictors, and long‐term impact of PPM in SAA TAVR.

Early clinical and hemodynamic results of transcatheter aortic valve implantation using the “MedLab-KT” prosthesis

Патология кровообращения и кардиохирургия, 2018
Background. The obvious expansion of mini-invasive technologies is looming large in surgical treatment of heart diseases. Hundreds of thousands of transcatheter aortic valve replacement procedures have been performed in the world today.

Annular Ellipticity and Sizing Strategy in Transcatheter Aortic Valve Implantation: Independent or Combined Risk Patterns?

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background Elliptical annular anatomy has been considered a risk factor for adverse outcomes after TAVI, particularly paravalvular leakage (PVL). Prosthesis oversizing is thought to improve sealing, but the interaction between annular shape and sizing strategy remains unclear.

Towards real-time cardiovascular magnetic resonance-guided transarterial aortic valve implantation: In vitro evaluation and modification of existing devices

Journal of Cardiovascular Magnetic Resonance, 2010
Background Cardiovascular magnetic resonance (CMR) is considered an attractive alternative for guiding transarterial aortic valve implantation (TAVI) featuring unlimited scan plane orientation and unsurpassed soft-tissue contrast with simultaneous device

Around and Through: Successful Mitral Paravalvular Leakage Closure Using Both Anterograde and Retrograde Approaches

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Paravalvular leak (PVL) is a recognized complication after surgical mitral valve replacement and may cause heart failure, pulmonary hypertension, or hemolysis when moderate or severe. Although redo surgery is the definitive treatment, it carries substantial risk in elderly patients or those with multiple prior cardiac surgeries.

Even a single positive blood culture may matter – A case of prosthetic valve infective endocarditis caused by Corynebacterium kroppenstedtii

IDCases
Corynebacterium is a skin commensal bacterium that can contaminate blood cultures. It is however also a rare cause of infective endocarditis (IE). Here we report a case of Corynebacterium kroppenstedtii aortic prosthesis IE in a 76-year-old man where ...

Transcatheter aortic valve implantation in failed bioprosthetic surgical valves. [PDF]

, 2014
IMPORTANCE: Owing to a considerable shift toward bioprosthesis implantation rather than mechanical valves, it is expected that patients will increasingly present with degenerated bioprostheses in the next few years.
