Mitochondria‐endoplasmic reticulum organelle glue as maturation promoter for origination/dimensional dual‐cross cardiomyocytes

BMEMat, EarlyView.
Mitochondria‐endoplasmic reticulum contact sites (MERCS) are areas where the mitochondria and endoplasmic reticulum closely interact. In this study, we utilize synthetic organelle glues to artificially engineer MERCS for regulating cardiomyocyte development, through which the immature and chemo‐plasticity issues of undifferentiated cells are addressed.

Left ventricular pacing in patients with preexisting tricuspid valve disease

Journal of Arrhythmia, 2019
Background Conventional right ventricular (RV) pacing is increasingly recognised to cause tricuspid valve (TV) injury or dysfunction, in part due to the need to pass the lead through the valve.

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.

Same‐Day Discharge After Transcatheter Aortic Valve Implantation: Who, When, and How?

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT The burden of severe aortic stenosis requiring treatment is growing due to ageing populations. This places increased demands on health resources due to the growing number of transcatheter aortic valve implantation (TAVI) procedures and hospital bed occupancy.

Transient 2:1 Atrioventricular Block with Peri-Conduction System Pacing After Leadless Pacemaker Implantation [PDF]

Texas Heart Institute Journal
This report discusses a case of transient 2:1 atrioventricular block with conduction system pacing 4 hours after leadless right ventricular pacemaker implantation in a 19-year-old patient with a history of cardioinhibitory syncope and asystole cardiac ...

The Impact of a Visualized Steerable Sheath on Radiofrequency Catheter Ablation for First‐Time Atrial Fibrillation Ablation: A Prospective, Randomized, Single‐Blind Study

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background A 3D electroanatomical mapping (3D‐EAM) visualized steerable sheath was designed to improve catheter placement and reduce radiation exposure during ablation, an established treatment for atrial fibrillation (AF). However, prospective randomized data comparing the procedural and clinical outcomes of visualized and non‐visualized ...

The incidence of in-hospital atrial fibrillation after coronary artery bypass grafting using ventricular and atrial pacing

ARYA Atherosclerosis, 2013
BACKGROUND: Atrial fibrillation (AF) after coronary artery bypass graft (CABG) surgery is a common problem. In this study, we sought to evaluate the safety and tolerance of continuous atrial pacing after CABG. We hypothesized that a strategy of temporary

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.

Effects of Cardiac Resynchronization Therapy on the Arrhythmic Substrate in a Patient with Long QT and Torsades de pointes

Journal of Arrhythmia, 2011
We describe a patient with torsades de pointes (TdP) who was implanted with cardiac resynchronization therapy defibrillator (CRT-D). At the time of CRT-D implantation, left ventricular (LV) epicardial pacing exacerbated TdPs and developed into electrical

Validation of an Automated Artificial Intelligence‐Driven Planner for Transcatheter Aortic Valve Replacement

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background Preprocedural planning with multislice computed tomography (MSCT) is an essential prerequisite for successful transcatheter aortic valve replacement (TAVR). However, preprocedural planning is time‐consuming and may contain clinically meaningful interobserver variability.
