Clinical Anatomy of the Left and Right Atrial Appendages in Humans: Comparative and Developmental Perspective

Clinical Anatomy, EarlyView.
ABSTRACT Human atrial chambers derive from distinct embryonic anlagens, the original embryonic atria gradually transforming into the so‐called auricles, or atrial appendages. This study quantifies macroscopic variations in pectinate muscle architecture in human atrial appendages and evaluates their visualization using clinical imaging modalities.

Bilateral Symmetry and Variation of Recurrent Laryngeal Nerve and Inferior Thyroid Artery Patterns: An Intraoperative Study of 150 Nerves

Clinical Anatomy, EarlyView.
ABSTRACT The anatomical relationship of the inferior thyroid artery (ITA) and the recurrent laryngeal nerve (RLN) is highly variable. This study aims to evaluate bilateral RLN branching patterns and their relationship to the ITA within the same patient, predicting contralateral anatomical variations and ultimately reducing intraoperative risk of RLN ...

Long-term outcomes after valve-sparing root replacement in patients with reduced left ventricular ejection fractionCentral MessagePerspective

JTCVS Open
Objective: Valve-sparing aortic root replacement (VSRR) is an established operation for aortic root pathology with aortic insufficiency (AI), with limited long-term data available in patients with reduced left ventricular ejection fraction (LVEF ...

Long‐Term Trends in Cardiac Erosion After Transcatheter Closure of Atrial Septal Defects With the Amplatzer Septal Occluder

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background Trends in cardiac erosion after closure of secundum atrial septal defects (ASD) with the Amplatzer Septal Occluder (ASO) have not been assessed since updates were made to the Instructions for Use in 2012 and 2018. This study evaluates the incidence and demographics of ASO erosion over time since its introduction in 1996.

A Randomized Controlled Trial Comparing the TruSteer and FXD Double Curve Delivery Systems for Left Atrial Appendage Occlusion With the Watchman FLX Pro Device—The GUIDE‐LAAO Study

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background Deflectable delivery systems have been introduced to enhance coaxial alignment and procedural efficacy during left atrial appendage occlusion (LAAO), yet randomized comparisons with conventional fixed‐curve systems are lacking. Aims The GUIDE‐LAAO trial evaluated whether the TruSteer deflectable delivery system is non‐inferior to ...

Quadricuspid Aortic Valve: Case Report and Brief Review [PDF]

Majallah-i Dānishgāh-i ’Ulūm-i Pizishkī-i Shahīd Ṣadūqī Yazd
Introduction: Quadricuspid Aortic Valve (QAV) is a rare congenital heart disease characterized by four leaflets that may be of identical or varying sizes. A less common scenario includes QAV accompanied by aortic valve stenosis.

Consecutive Emergency Carotid Artery Stenting and Transcatheter Aortic Valve Replacement in a Patient With Cardiogenic Shock: A Case Report

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Severe aortic stenosis (AS) carries a poor prognosis when symptomatic, particularly in cardiogenic shock (CS). Emergency transcatheter aortic valve replacement (TAVR) is rarely performed but may represent a rescue therapy. Coexistent carotid artery stenosis (CAS) further increases procedural risk.

Expression of mutant TIE2 p.L914F during mouse development causes embryonic lethality and defects in vascular remodeling

Developmental Dynamics, EarlyView.
Abstract Background Sporadic venous malformation (VM) is associated with the hyperactivating p.L914F mutation in TIE2, a receptor tyrosine kinase essential for vascular development. This mutation is not found in hereditary VM, suggesting incompatibility with life when expressed during early vascular development.

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.
