Diagnostic Accuracy and Feasibility of Quantitative Flow Ratio at Low Frame Rate Angiography: The Prospective Multicentre Australian AVALON Study

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background Quantitative Flow Ratio (QFR) is a well‐established, non‐hyperemic, angiographic, wire‐free predictor of ischemia when compared to Fractional Flow Reserve (FFR). However, its diagnostic accuracy at low frame rates (< 10 frames/second), commonly used in contemporary practice to minimize radiation exposure, has not been evaluated ...

Use of Intracoronary Pressure Wire Assessment and Association With Outcomes: Insights From the British Cardiovascular Intervention Society National Database

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background Despite recommendations in international guidelines, Intracoronary pressure wire assessment (PWA) utilization remains limited in clinical practice. This study aims to describe (i) trends of PWA during Percutaneous coronary interventional (PCI), (ii) factors that predict its application, and (iii) association with in‐hospital ...

Quadricuspid aortic valve: a rare cause of aortic regurgitation and stenosis

The Turkish Journal of Pediatrics, 2008
Quadricuspid aortic valve is a rare congenital condition that occurs not only as an isolated anomaly, but also with other cardiac defects. We describe a 10-year-old boy whose aortic stenosis was diagnosed during infancy.

Comparison Between the Acurate Neo and the Acurate Neo 2 Transcatheter Heart Valve System: Impact of Midframe Under‐Expansion

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background Transcatheter aortic valve implantation (TAVI) with the Acurate Neo has been linked to a significant incidence of paravalvular leakage (PVL), addressed by the Acurate Neo 2 incorporating an active sealing skirt. Recent findings suggest that midframe under‐expansion is associated with worse outcomes.

The Incidence, Severity and Clinical Consequence of Left Pulmonary Artery Stenosis After PDA Device Closure in Premature Infants Less Than 2 Kilograms

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background Transcatheter patent ductus arteriosus (PDA) device closure is an effective treatment option for premature infants with hemodynamically significant PDA. Left pulmonary artery (LPA) stenosis has been reported as a complication, however there is limited data on risk factors, clinical significance, and long‐term outcomes.
