Prediction of Turbulent Shear Stresses through Dysfunctional Bileaflet Mechanical Heart Valves using Computational Fluid Dynamics

, 2018
There are more than 300,000 heart valves implanted annually worldwide with about 50% of them being mechanical valves. The heart valve replacement is often a common treatment for severe valvular disease.

Transcatheter Aortic‐Valve Replacement with a Balloon‐Expandable Valve in Low‐Risk Patients

New England Journal of Medicine, 2019
BACKGROUND Among patients with aortic stenosis who are at intermediate or high risk for death with surgery, major outcomes are similar with transcatheter aortic‐valve replacement (TAVR) and surgical aortic‐valve replacement.

Intravascular Lithotripsy Is Associated With Superior Clinical Outcomes Compared to Atherectomy: A Large‐Scale, Propensity‐Matched Analysis

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background Coronary artery disease (CAD) with severe calcification remains a growing challenge in percutaneous coronary intervention (PCI). Atherectomy (ATH) has long been used for plaque modification, whereas intravascular lithotripsy (IVL) has emerged as a promising alternative. Large‐scale comparative data on long‐term outcomes are limited.

Rationale and design of the randomized, controlled Early Valve Replacement Guided by Biomarkers of Left Ventricular Decompensation in Asymptomatic Patients with Severe Aortic Stenosis (EVOLVED) trial.

American Heart Journal, 2019
BACKGROUND The optimal timing of aortic valve replacement in asymptomatic patients with aortic stenosis is uncertain. Replacement fibrosis, as assessed by midwall (nonischemic) late gadolinium enhancement (LGE) on cardiac magnetic resonance (CMR) imaging,

Predicting Coronary Occlusion Risk during Redo‐TAVR at First TAVR: Asymmetric Calcification Causes Failure

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background and Aims Predicting coronary artery occlusion due to sinus sequestration (SS) during a second transcatheter aortic valve (TAV) procedure using pre‐procedural computed tomography (CT) after the first TAV replacement (TAVR) is underreported.

Balloon‐Expandable Versus Self‐Expanding Valves in Low‐Flow, Low‐Gradient Aortic Stenosis: Does Valve Type Matter?

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background The optimal choice between balloon‐expandable (BE) and self‐expanding (SE) transcatheter heart valves (THVs) in patients with low‐flow low‐gradient aortic stenosis (LFLG AS) undergoing transcatheter aortic valve replacement (TAVR) remains unclear.
