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.

Composite valved apico-aortic conduits for left ventricular outflow obstruction.

Acta Médica Portuguesa, 1980
Problems related to the left ventricular outflow tract are not always amenable to conventional surgical methods, and in some cases may be solved with the creation of a double outlet left ventricle, using a composite rigid pyrolite left ventricular apex ...

Outcomes in Patients With Obstructive Hypertrophic Cardiomyopathy and Concomitant Aortic Stenosis Undergoing Surgical Myectomy and Aortic Valve Replacement

Journal of the American Heart Association: Cardiovascular and Cerebrovascular Disease, 2021
Background Hypertrophic cardiomyopathy (HCM) and aortic stenosis can cause obstruction to the flow of blood out of the left ventricular outflow tract into the aorta, with obstructive HCM resulting in dynamic left ventricular outflow tract obstruction and

Mechanisms, pathophysiology, and diagnostic imaging of left ventricular outflow tract obstruction following mitral valve surgery and transcatheter mitral valve replacement

, 2019
© 2019 Wiley Periodicals, Inc. Left ventricular outflow tract obstruction is a serious complication of mitral valve surgery (repair and replacement) and transcatheter mitral valve replacement. An appreciation of the various mechanisms which cause outflow

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.

Obstructive Lesions of the Left Ventricular Outflow Tract [PDF]

Circulation, 1965
Currently available diagnostic methods and surgical technics now allow accurate assessment and effective correction of the majority of lesions producing obstruction of the left ventricular outflow tract. On the basis of anatomic location these lesions can be divided into supravalvular, valvular, and subvalvular stenosis, and valvular lesions further ...
