We present the case of a 4-month-old child with atrioventricular canal associated with severe left atrioventricular valve dysfunction who previously underwent 3 surgical valve reconstructions without significant improvement. A Hybrid Melody valve (Medtronic, Minneapolis, MN) insertion was planned. Because of the low weight, the risk of left ventricular outflow tract obstruction was significant and therefore evaluated preprocedurally using a cardiac computed tomography-derived 3-dimensional printed model. In vitro tests showed good anchorage of the valve without subaortic obstruction and the procedure was then achieved with an excellent clinical result.

Distribution and sequence analysis of the melanocortin 2 receptor in horses and ponies.

Domest Anim Endocrinol

January 2025

School of Biology and Environmental Science, Queensland University of Technology, Brisbane, Queensland, Australia. Electronic address:

The melanocortin 2 receptor (MC2R) has relevance to equine pituitary pars intermedia dysfunction (PPID), as it is the primary binding site for ACTH, which circulates at elevated concentrations in animals affected by PPID. Despite this, little is known about MC2R in equine species. The overall aim of this investigation was to determine MC2R mRNA expression in tissues relevant to PPID in healthy horses and to examine the MC2R gene sequence in a cohort of horses and ponies with and without PPID.

Unmet Clinical Needs for Transcatheter Pulmonary Valves.

Ann Biomed Eng

November 2023

Department of Biomedical Engineering, University of California, 2420 Engineering Hall, Irvine, CA, 92697-2730, USA.

A common feature of congenital heart disease is the presence of right ventricular outflow tract (RVOT) obstruction that can range from mild to severe and can lead to atresia of the pulmonary valve, in extreme conditions. RVOT abnormalities can frequently be corrected surgically or via interventional means. However, most of these patients will ultimately develop pulmonary valve insufficiency and eventual right ventricular dilation, which will require a pulmonary valve replacement at some point in their life to mitigate the detrimental effects of pulmonary valve regurgitation (PVR) on the right ventricle (RV).
