In situ pressure-radius-length measurements in ascending aorta of anesthetized dogs

, 1964
Instantaneous pressure-radius-length relationship was studied in the ascending aorta of ten living dogs. Results indicate: 1) longitudinal and circumferential strains in the ascending aorta are large as compared to other segments of the aorta, and 2) it

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 ...

Feasibility and Procedural Considerations of Balloon‐Expandable TAVR in Patients With Prior Endovascular Aortic Stent Grafts

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Objectives To evaluate the feasibility and short‐term outcomes of transcatheter aortic valve replacement (TAVR) using balloon‐expandable Sapien valves in patients with prior endovascular aortic stent grafts. Methods We conducted a single‐center, retrospective study of 23 patients with prior endovascular aortic stent grafts who underwent TAVR ...

Diagnostic Agreement and Threshold Correspondence Between Resting Full‐Cycle Ratio and Nicorandil‐Based Fractional Flow Reserve in Intermediate Coronary Stenosis: A Prospective Single‐Center Registry

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background RFR has shown good aggregate agreement with FFR, including in prior Asian cohorts using intracoronary nicorandil. Where RFR‐FFR disagreement is concentrated relative to the FFR 0.80 decision boundary, and how the two binary thresholds correspond, remain incompletely characterized. Methods In a prospective single‐center registry, 300

Double Transeptal Puncture for SAPIEN M3 Transcatheter Mitral Valve Replacement: Initial Experience, Indications, and Technique

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT The SAPIEN M3 system has been recently approved for transcatheter mitral valve replacement (TMVR). The transeptal guide sheath is used to deploy the dock, which is completely released before inserting and deploying the M3 valve using the same femoral access, transeptal puncture (TSP) and guide sheath.

The Triple Wire Dual Angioseal Technique for Large Bore Femoral Access Closure

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT There is a growing need for large‐bore femoral access across cardiac interventions. This has led to a need for more widely accessible vascular closure techniques to facilitate reliable vascular closure and wider access to these interventions.

Secretopathies emerge as a new class of neurocristopathies

Developmental Dynamics, EarlyView.
Abstract Neural crest cells are a transient embryonic population of cells that give rise to a wide range of structures, including craniofacial cartilage and bone, peripheral neurons and glia, as well as components of the cardiac outflow tract, among others.

Loss of POGLUT2/3‐mediated O‐glucosylation produces lung and aortic phenotypes reminiscent of fibrillin1 mutants

Developmental Dynamics, EarlyView.
Abstract Background Fibrillins provide a scaffold for elastic fiber formation, which enables lung recoil and aortic compliance. Abnormal fibrillin microfibrils, as in Marfan syndrome, lead to enlarged alveoli, vascular stiffening, and aneurysms. Our earlier studies suggested that fibrillin function depends on O‐glucosylation of its epidermal growth ...
