Reduced elastogenesis: a clue to the arteriosclerosis and emphysematous changes in Schimke immuno-osseous dysplasia? [PDF]

, 2012
BACKGROUND: Arteriosclerosis and emphysema develop in individuals with Schimke immuno-osseous dysplasia (SIOD), a multisystem disorder caused by biallelic mutations in SMARCAL1 (SWI/SNF-related, matrix-associated, actin-dependent regulator of chromatin,

Postcardiotomy Mechanical Circulatory Support in Two Infants with Williams’ Syndrome

Case Reports in Surgery, 2014
Supravalvar aortic stenosis (SVAS) in patients with Williams’ syndrome is often accompanied by coronary, pulmonary, and even myocardial lesions and therefore associated with increased perioperative morbidity and mortality.

Obstetric outcome in women with congenital heart disease: A nationwide cohort in Sweden

Acta Obstetricia et Gynecologica Scandinavica, Volume 105, Issue 1, Page 7-17, January 2026.
In this large national case–control study in women with congenital heart disease, we showed an increased likelihood of giving birth prematurely, by cesarean section, and having a small‐for‐gestational‐age neonate compared to matched controls. Abstract Introduction Survival and healthcare for patients with congenital heart disease have improved, and the

The “Long‐Sheath” Technique in Percutaneous Aortic Balloon Valvuloplasty [PDF]

, 1988
A new 100 cm long 16.5 French valvuloplasty introducer was used in 12 consecutive patients (mean age 73 years, five males and seven females) undergoing aortic balloon valvuloplasty for severe aortic stenosis.

Adjustments in β-Adrenergic Signaling Contribute to the Amelioration of Cardiac Dysfunction by Exercise Training in Supravalvular Aortic Stenosis.

Cellular Physiology and Biochemistry, 2020
BACKGROUND/AIMS Aortic stenosis-induced chronic pressure overload leads to cardiac dysfunction and congestive heart failure. The pathophysiological mechanisms of the myocardial impairment are multifactorial and include maladaptive β-adrenergic signaling.

Echocardiographic evaluation of velocity ratio, velocity time integral ratio, and pulmonary valve area in dogs with pulmonary valve stenosis. [PDF]

, 2018
BackgroundVelocity ratio, velocity time integral (VTI) ratio, and pulmonary valve area indexed to body surface area (iPVA) are methods of assessment of pulmonary valve stenosis (PS) severity that are less dependent on blood flow. Studies evaluating these

Identification and characterization of novel elastin gene mutations in eleven families with supravalvular aortic stenosis

Frontiers in Genetics, 2022
Background: Supravalvular aortic stenosis (SVAS) is a rare congenital heart disease affecting approximately 1 in 25,000 live births. In some patients it is accompanied by pulmonary artery stenosis, particularly of pulmonary artery branches.

Unforeseen beneficial effect of successful PVC ablation: Achieving migraine attack control without medication

Journal of Arrhythmia, Volume 41, Issue 4, August 2025.
Successful catheter ablation of frequent PVCs in a patient with PVC‐induced cardiomyopathy resulted in a marked improvement in left ventricular ejection fraction (LVEF), accompanied by complete resolution of migraine with aura attacks. This case illustrates both cardiac and neurological benefits of PVC burden reduction through ablation.

Management of supravalvular aortic stenosis with the Doty technique, in a South American pediatric center

Archivos de Cardiología de México
Supravalvular aortic stenosis (SVAS) is a congenital malformation associated with Williams-Beuren syndrome. It is characterized by severe stenosis of the sinotubular junction. The smooth muscle layer is thickened due to an alteration of the Elastin gene.

Cardiac outcomes in adults with supravalvar aortic stenosis [PDF]

, 2017
Aims Supravalvar aortic stenosis is a rare form of left ventricular outflow tract obstruction that is often progressive in childhood. Little data are available on outcomes in the adult population.
