Pacing and Clinical Electrophysiology, EarlyView.ABSTRACT Background/Objectives Right ventricular (RV) apical pacing, the standard pacing approach, often induces ventricular dyssynchrony, potentially impairing cardiac function. This study aims to investigate whether targeted RV septal pacing, guided by functional electrophysiological feedback during implantation, reduces ventricular dyssynchrony ...

Spontaneous Resolution of Left Ventricular Outflow Tract Obstruction in the Course of Newly-Developed Mitral Valve Prolapse in a Hypertrophic Cardiomyopathy Patient [PDF]
A 63-year-old man was diagnosed with hypertrophic obstructive cardiomyopathy. Echocardiography revealed asymmetrical left ventricular hypertrophy, systolic anterior movement (SAM) of mitral leaflets causing an outflow tract pressure gradient of 52 mmHg ...

Cardiac rhabdomyoma in an adult patient presenting with right ventricular outflow tract obstruction
, 2008 We present a 24 year old woman with cardiac rhabdomyoma. Cardiac rhabdomyoma is the most common benign cardiac tumor in infants, but in adults, cardiac rhabdomyoma is very rare.

Calcium‐activated chloride channels in pericytes and their role in regulating organ blood flow
The Journal of Physiology, EarlyView.Abstract figure legend Pericytes are microvascular mural cells with diverse roles. Contractile pericytes directly regulate local perfusion, while non‐contractile pericytes coordinate upstream vascular contractility via propagating electrical signals.

Left ventricular outflow obstruction in rhabdomyoma of infancy: meta-analysis of the literature
, 2003 Primary heart tumors are exceptional in infants and children. Most common is the rhabdomyoma, often associated with tuberous sclerosis (Bourneville's disease).

The Journal of Physiology, EarlyView.Abstract figure legend The capillary–mitochondria–ion channel (CMIC) axis scales structural resources to match functional workload. (Left) In settings of restricted energetic capacity (e.g. cortical neurons), sparse capillary networks and modest mitochondrial pools set a lower energetic ceiling, sufficient to support phasic, low‐workload excitability.

Caenorhabditis elegans as an in vivo model system for human inherited primary arrhythmia syndromes
The Journal of Physiology, EarlyView.Abstract figure legend Most genes involved in inherited primary arrhythmia syndromes (IPAS) are conserved in Caenorhabditis elegans, where genetic manipulation enables functional characterization of variants, identification of regulatory proteins, and in vivo drug testing.
