Paravalvular leakage of transcatheter aortic valve replacements depending on aortic annulus calcification

Current Directions in Biomedical Engineering, 2021
Paravalvular leakage (PVL) has a crucial impact on clinical outcomes of transcateheter aortic valve replacements (TAVR), especially the mortality increases dramatically with high-grade PVL.

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.

Prevalence of Panton-Valentine leukocidin-positive methicillin-susceptible Staphylococcus aureus infections in a Saudi Arabian hospital

Journal of Infection and Public Health, 2015
Summary: Panton-Valentine leukocidin (PVL) is a two-component toxin associated with the toxicity and virulence of Staphylococcus aureus. The presence of PVL is well documented in community-acquired methicillin-resistant S.

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.

Panton-Valentine Leukocidin (PVL) genes may not be a reliable marker for community-acquired MRSA in the Dakahlia Governorate, Egypt

BMC Microbiology, 2023
Background Methicillin-resistant Staphylococcus aureus is linked to both nosocomial and community infections. One of the key virulence factors of S. aureus is Panton-Valentine leukocidin (PVL).

Cardiovascular magnetic resonance and transesophageal echocardiography in patients with prosthetic valve paravalvular leaks: towards an accurate quantification and stratification

Journal of Cardiovascular Magnetic Resonance, 2021
Background Objective assessment of prosthetic paravalvular leak (PVL) is complex and challenging even in transesophageal echocardiography (TEE). Our aim was to assess the value of cardiovascular magnetic resonance (CMR) in quantifying PVL in aortic (AVR)
