Tricuspid valve surgery for acute infective endocarditis can be performed with very low operative mortalityCentral MessagePerspective

JTCVS Open
Objective: Tricuspid valve surgery historically has been perceived as having elevated operative risk, prompting the recent development of transcatheter therapies including aspiration vegetectomy for endocarditis.

pKa engineering of a near‐infrared fluorescent probe for sensitive imaging of oxidative stress in atherosclerotic plaques

Smart Molecules, EarlyView.
A pKa‐engineered near‐infrared fluorescent probe (DCM‐2F‐B) enables sensitive imaging of oxidative stress in atherosclerotic plaques. Difluoro substitution lowers the phenolic hydroxyl pKa from 9.1 to 6.0, achieving near‐complete ionization at physiological pH.

Acute, reversible tricuspid insufficiency: creation in canine model

, 1991
Relatively few methods have been described for the creation of valvular insufficiency in an animal model. Those presented involve limitations such as permanent destruction of the valves or lack of control over the degree of regurgitation produced.

Safety and efficacy of total thoracoscopic surgery for patients with tricuspid regurgitation and reduced right ventricular function after left heart valves replacement: a retrospective comparative study

BMC Cardiovascular Disorders, 2023
Background Tricuspid valve surgery is the standard treatment for tricuspid valve disease refractory to pharmacologic therapy. However, patients with tricuspid regurgitation after previous left heart valves replacement with reduced right ventricular (RV ...

Spectrum of Congenital Malformations in Sex Chromosome Tetrasomies and Pentasomies: A Systematic Review

Andrology, EarlyView.
ABSTRACT Sex chromosome aneuploidies represent a heterogeneous group of chromosomal conditions, in which phenotypic complexity generally increases with the number of supernumerary sex chromosomes. While Turner syndrome and sex chromosome trisomies are relatively well characterized, less is known about congenital malformations in sex chromosome ...

Can Tricuspid Annuloplasty of the Donor Heart Reduce Valve Insufficiency following Cardiac Transplantation with Bicaval Anastomosis?

, 2010
Background: The aim of this study was to evaluate the degree of tricuspid valve insufficiency after orthotopic cardiac transplantation with bicaval anastomosis and prophylactic donor heart annuloplasty.

Prenatal imaging phenotypes and outcomes of umbilical‐portal‐systemic venous shunts in singleton and twin pregnancies: A historical cohort study

Acta Obstetricia et Gynecologica Scandinavica, EarlyView.
This retrospective cohort compared umbilical‐portal‐systemic venous shunts in singleton and twin pregnancies. Type III was the most common subtype in singletons, whereas Type II was the most common in twins. Fetal growth restriction was more frequent in twins, but primary structural anomaly rates were similar.

Ebstein's anomaly in a newborn with prenatal diagnosis

Revista Electrónica Dr. Zoilo E. Marinello Vidaurreta, 2017
Ebstein's anomaly encompasses a wide spectrum of abnormalities, characterized by different degrees of displacement and adhesion of the septal and posterior dysplastic valve of the tricuspid to the right ventricle cavity.

Modified underlying cardiac disease severity in twin-twin transfusion syndrome

Annals of Pediatric Cardiology, 2019
Twin-twin transfusion syndrome or related conditions affect fetal loading. We report monochorionic-diamniotic twins. Twin 1 had Ebstein anomaly with mild tricuspid regurgitation (TR) and slightly thickened tricuspid valve leaflets with plastering. Twin 2

An Optimized Multi‐Stage Drainage Cannula Design for Venoarterial Extracorporeal Membrane Oxygenation

Artificial Organs, EarlyView.
This study utilized an extensive optimization involving n = 540 design of experiments to produce a superior drainage cannula design. Compared to the clinically used Maquet model, our optimized design demonstrated reduced blood stagnation volumes, increased cannula tip velocities, and higher upper body drainage, potentially minimizing risk of thrombosis
