Systematic Cardiac Phenotyping of Patients With Copy Number Variants in the 15q11.2 Breakpoint 1 to Breakpoint 2 Region: A Retrospective Cohort Study From Nine Pediatric Cardiac Centers

American Journal of Medical Genetics Part A, EarlyView.
ABSTRACT Microdeletions impacting 15q11.2 breakpoint (BP) 1 to BP2, adjacent to the Prader–Willi critical region, have previously described neuropsychiatric associations, with potential low penetrance presentations of congenital heart disease (CHD) also identified.

Longitudinal Echocardiographic Surveillance of Aortic Dilation in a Phenotype‐Enriched Turner Syndrome Cohort

American Journal of Medical Genetics Part A, EarlyView.
ABSTRACT Turner syndrome (TS) is associated with thoracic aortopathy and increased risk for aortic dissection, yet the natural history of aortic dilation is not well understood. We performed a retrospective longitudinal study of individuals with TS who participated in the TS Society of the United States Healthy Heart Project between 2003 and 2023 ...

Congenital Absence of the Pulmonary Valve [PDF]

Circulation, 1957
The autopsy on a 32-year-old man revealed an absence of the pulmonary valve, a ventricular septal defect, and a single coronary artery. Congenital absence of the pulmonary valve has not been previously reported. The diagnosis of the accompanying pulmonary incompetence is discussed in the light of the catheterization studies and clinical findings.

Cardiac morphological and morphometric analysis of Ardea alba

The Anatomical Record, EarlyView.
Abstract Ardea alba (Linnaeus, 1758) is a widely distributed heron species whose cardiovascular morphology remains poorly described. This study aimed to characterize the cardiac morphology and morphometry of adult A. alba. Ten specimens were analyzed using radiographic, morphometric, histological, scanning electron microscopy, and three‐dimensional ...

Isolated Pulmonary Valve Endocarditis Complicated With Septic Emboli to the Lung Causing Pneumothorax, Pneumonia, and Sepsis in an Intravenous Drug Abuser

Journal of Investigative Medicine High Impact Case Reports, 2013
Intravenous drug users are at increased risk for developing right-sided infective endocarditis involving the tricuspid and pulmonary valves. Isolated pulmonary valve endocarditis in intravenous drug users is very rare, and these patients often have more ...

SOX6 is expressed in various cell lineages in the developing mouse heart and contributes to proper valvuloseptal development

The Anatomical Record, EarlyView.
Abstract Cells derived from the endocardium, epicardium, cardiac neural crest, and second heart field play a critical role in the formation of the valvuloseptal structures of the heart. Previous studies have shown that the expression of the transcription factor SOX9 in these cell populations is essential in the regulation of this process.

“Inverted Pulmonary Valve,” a Rare Cause of Severe Pulmonary Stenosis

Journal of the Indian Academy of Echocardiography & Cardiovascular Imaging
We describe three cases – two detected prenatally and one postnatally – in which the pulmonary valve exhibited abnormal chord-like attachments to the right ventricle. This produced paradoxical valve motion, characterized by closure in systole and opening

Valve-sparing repair with skeletonization of the pulmonary annulus for tetralogy of Fallot [PDF]

, 2019
Pulmonary valve preservation in tetralogy of Fallot (TOF) repair is one of the most challenging issues. Herein, we describe a novel valve-sparing technique for TOF repair that primarily consists of skeletonization of the anterior part of the ...
