3D transparent technology displays the developmental patterns of ductus arteriosus morphology in chicken embryos before and after birth

open access: yesJournal of Anatomy, EarlyView.
At the eighth week of human embryonic development, 3D transparent imaging enables clear visualization of the outflow tract's morphological features, revealing its anatomical components in detail. Abstract The ductus arteriosus (DA) is a critical fetal vascular structure that shunts blood from the pulmonary artery to the aorta, bypassing the non ...

Long‐term outcomes following modified Blalock–Taussig–Thomas shunt placement in 13 dogs with cyanotic congenital heart disease

open access: yesJournal of Small Animal Practice, EarlyView.
Objectives To describe long‐term outcome and owner‐perceived quality of life in dogs with cyanotic congenital cardiac disease undergoing modified Blalock–Taussig–Thomas shunt procedure. Materials and Methods Medical records of dogs that underwent Blalock–Taussig–Thomas shunt between 2009 and 2025 at a small animal referral hospital were retrospectively

RIGHT VENTRICULAR MYXOMA WITH SYNCOPE BY THE OBSTRUCTION OF RJGHT VENTRICULAR OUTFLOW TRACT

open access: yes, 2006
We report a rare case of right ventricular myxoma that was almost occupying the right ventricular outflow tract. The patient was admitted for syncope, and three-dimensional reconstruction of the heart using multislice spiral computed tomography made ...

Ventricular Synchrony in Targeted Right Ventricular Septal Pacing: A Prospective Paired Comparison to Apical Placement

open access: yesPacing 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 ...

Improving left ventricular outflow tract obstruction repair in common atrioventricular canal defects

open access: yes, 2012
Left ventricular outflow tract obstruction (LVOTO) is the second most frequent reason for reoperation after atrioventricular canal (AVC) defect repair.

Transcatheter closure of Ventricular Septal defects in Malta : initial experience [PDF]

open access: yes, 2005
Ventricular septal defects (VSD) consist of deficiencies of the wall separating the two ventricles. VSDs are the commonest congenital cardiac defects. Small VSDs rarely require intervention, however, larger defects cause ventricular volume overload with ...

Calcium‐activated chloride channels in pericytes and their role in regulating organ blood flow

open access: yesThe 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.

Energetic microdomains and the vascular control of neuronal and muscle excitability: Toward a unified model

open access: yesThe 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.
