Catheterization and Cardiovascular Interventions, EarlyView.ABSTRACT Backgrounds Accurate stent positioning in aorto‐ostial lesions remains challenging due to complex three‐dimensional anatomy, lack of optimal fluoroscopic projections, and high rates of geographic miss. Stent overhang impairs guide catheter re‐engagement and complicates future revascularization.

Aortic root replacement for bicuspid aortic valve dysfunction does not impair survival rates
Journal of Cardiothoracic SurgeryBackground Patients with a bicuspid aortic valve carry an increased risk for developing an ascending aortic aneurysm due to intrinsic aortic wall alterations.

A coupled mitral valve -- left ventricle model with fluid-structure interaction
, 2017 Understanding the interaction between the valves and walls of the heart is important in assessing and subsequently treating heart dysfunction. With advancements in cardiac imaging, nonlinear mechanics and computational techniques, it is now possible to ...

Catheterization and Cardiovascular Interventions, EarlyView.ABSTRACT Background Mitral regurgitation (MR) is the valent type of valvular heart disease, caused by primary leaflet lesions or annular dilatation secondary to left ventricular dysfunction. It can lead to a series of complications such as volume overload, exacerbated pulmonary congestion, and heart failure, significantly impacting patient prognosis ...

Disruption of Notch1 and Gata5 in Mice Leads to Congenital Aortic Valve Disease
JACC: Basic to Translational ScienceSummary: Here, we describe Notch1;Gata5 compound mutant mice as a novel mouse model of highly penetrant congenital aortic valve disease displaying bicuspid aortic valve and progressive aortic valve stenosis.

Catheterization and Cardiovascular Interventions, EarlyView.ABSTRACT Background Development of conduction abnormalities requiring pacing after transcatheter aortic valve replacement (TAVR) is relatively common. The effects of post‐TAVR permanent pacemaker (PPM) implantation on mortality, ischemic stroke, and cardiovascular outcomes remain incompletely characterized.

The Journal of ExtraCorporeal Technology, 1990 Indications for aortic valve replacement can be summarized into two disease processes, moderate to severe aortic stenosis (with or without symptoms) and moderate to severe aortic insufficiency. Fortunately, standards of care differ with each physician and so indications for aortic valve replacement are not clearly defined. To understand how the surgeon

Outcomes of Left Atrial Appendage Occlusion in Heart Failure With Reduced Ejection Fraction
Catheterization and Cardiovascular Interventions, EarlyView.ABSTRACT Background Patients with heart failure with reduced ejection fraction (HFrEF) were excluded from major trials of left atrial appendage occlusion (LAAO). Aim The objective of this study was to describe this population and evaluate outcomes after LAAO in patients with and without HFrEF.

Catheterization and Cardiovascular Interventions, EarlyView.ABSTRACT Background Atrial fibrillation (AF) is a frequent comorbidity in patients with severe aortic valve stenosis undergoing transcatheter aortic valve implantation (TAVI). In addition, new‐onset AF can occur after TAVI. However, data on how AF affects outcomes in patients undergoing TAVI remain conflicting.
