Plicated patch repair for acquired Gerbode defect involving the tricuspid valve

, 2010
Gerbode's defect, a left ventricular-to-right atrial communication, with involvement of the tricuspid valve acquired after bacterial endocarditis can be challenging to repair.

Transvalvular Pressure Gradients for different Methods of Mitral Valve Repair only Neochordoplasty achieves native Valve Gradients [PDF]

, 2017
OBJECTIVES: Many surgical and interventional methods are available to restore patency for patients with degenerative severe mitral valve regurgitation. Leaflet resection and neochordoplasty, which both include ring annuloplasty, are the most frequently ...

1T‐to‐2H Phase Evolution During Epitaxial Growth of Transition Metal Dichalcogenides

Advanced Materials, EarlyView.
During MOCVD growth of MoS2 and WSe2, a transient metallic 1T phase emerges in early, edge‐rich, chalcogen‐deficient domains and declines as the films ultimately coalesce as 2H material. Together, experiments and ReaxFF simulations link domain size, edge stoichiometry, and vacancies to this evolution.

Cost-Effectiveness of Intraoperative Transesophageal Echocardiography in Cardiac Valve Surgery

Journal of Cardiovascular and Thoracic Research, 2011
Introduction: Being a unique diagnostic technique, transesophageal echocardiography (TEE) has influenced many different aspects of cardiac surgery including valve repair surgery. The cost-effectiveness of this method however is questioned considering the

A Constraint‐Based Analytical Framework for Design‐Space Analysis and Material Screening of Tubular Multilayer Dielectric Elastomer Pumps for Extracorporeal Circulatory Applications

Advanced Materials Technologies, EarlyView.
A constraint‐based analytical framework maps the coupled effects of material properties, structural parameters, and operating conditions in tubular dielectric elastomer pumps for extracorporeal circulatory applications. The approach defines performance boundaries through mechanical, electrical, and hydraulic constraints and identifies feasible design ...

Surgical strategies protecting against right ventricular dilatation following tetralogy of Fallot repair

Journal of Cardiothoracic Surgery, 2018
Background Right ventricular (RV) volume overload increases morbidity and mortality after tetralogy of Fallot (TOF) repair. Surgical strategies like pulmonary leaflets sparing and tricuspid valve repair at time of primary repair may decrease RV overload.

Ring-first Mitral Valve Repair [PDF]

, 2020
Mitral valve repair is one of the most frequent interventions in cardiac surgery. It involves eliminating the dysfunctional part(s) of the mitral valve and reconstructing, using the residual tissue or with the addition of prosthetic components, a ...
