Hyperbranched poly‐L‐lysine surface‐engineered bioprosthetic heart valves with anti‐calcification, anti‐infection, and durability

BMEMat, EarlyView.
The challenges of bioprosthetic heart valves (BHV) with respect to calcification, infection, and poor durability are tackled by surface engineering of hyperbranched poly‐L‐lysine (HBPL), providing a translational solution to improve long‐term valve performance.

Long-term Mortality Predictors in Patients with Small Aortic Annulus Undergoing Aortic Valve Replacement with a 19- or 21-mm Bioprosthesis

Brazilian Journal of Cardiovascular Surgery
Introduction: Replacement of the aortic valve in patients with a small aortic annulus is associated with increased morbidity and mortality. A prosthesis-patient mismatch is one of the main problems associated with failed valves in this patient population.

Clinical research regional vascular changes and aortic dilatation in pediatric patients with bicuspid aortic valve

, 2022
: Background: Bicuspid aortic valve (BAV) is the most common congenital heart disease, often associated with valve dysfunction, coarctation of the aorta, and ascending aorta dilatation.

Clinical Anatomy of the Left and Right Atrial Appendages in Humans: Comparative and Developmental Perspective

Clinical Anatomy, EarlyView.
ABSTRACT Human atrial chambers derive from distinct embryonic anlagens, the original embryonic atria gradually transforming into the so‐called auricles, or atrial appendages. This study quantifies macroscopic variations in pectinate muscle architecture in human atrial appendages and evaluates their visualization using clinical imaging modalities.

Observations on Two Previously Unreported Anatomical Factors Relating to the Esophagogastric Junction

Clinical Anatomy, EarlyView.
ABSTRACT The esophagogastric junction (EGJ) is the anatomical zone where the esophagus ends and the stomach begins. Its competence in preventing gastro‐esophageal reflux has been shown to depend on a number of factors which have been extensively investigated and widely accepted.

The Establishment of a Transaxillary Minimally Invasive Aortic Valve Replacement Program: Considerations and First Patient Outcomes

The Heart Surgery Forum
Background: As minimally invasive and alternative approaches for aortic valve repair gain increased popularity, this trial reports on outcomes of an established program using the underreported novel right transaxillary (rTX) access for

Bioprosthetic Aortic Valve Fracture During Valve-in-valve Transcatheter Aortic Valve Implantation [PDF]

, 2019
The limited durability of surgical bioprostheses, combined with an ageing population, has led to an increasing demand for replacing degenerated bioprosthetic surgical heart valves, which is projected to increase. Valve-in-valve transcatheter aortic valve

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 ...

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.

CT-based visualization of aortic valve morphology: from 3D energy-integrating CT to 4D photon counting CT

Frontiers in Cardiovascular Medicine
BackgroundWhile 4D contrast-enhanced computed tomography (CT) is used to plan cardiovascular interventions such as transcatheter valve replacement, it is not yet routinely used to characterize minimally calcified aortic valves for planning of surgical ...
