Aortic valvuloplasty of calcific aortic stenosis with monofoil and trefoil balloon catheters: practical considerations [PDF]

, 1990
In order to evaluate the relation between balloon design (monofoil, trefoil) and valvular configuration, experimental aortic valvuloplasty was performed in four post-mortem hearts with calcific aortic ...

Perinatal outcomes of resolved fetal cystic hygromas

Pregnancy, Volume 1, Issue 4, July 2025.
Abstract Introduction Cystic hygroma is associated with additional fetal anomalies and genetic abnormalities. Although some cystic hygromas can progress to hydrops fetalis, some regress and resolve with advancing gestation. We aimed to describe the frequency with which cystic hygromas resolve, the prevalence and types of underlying genetic diagnoses ...

Endocardial-mesenchymal transition underlies fusion of the conotruncal ridges during embryonic cardiac outflow tract septation [PDF]

, 2018
The embryonic cardiac outflow tract (conotruncus) is a single tubular chamber that connects the right ventricle with the aortic arch arteries. It contains two opposite, long and helical mesenchymal cushions covered by endocardial cells (conotruncal ...

Comparison of incidence, prevalence and death of aortic stenosis and aortic insufficiency in a nationwide Korean study

ESC Heart Failure, Volume 12, Issue 3, Page 2245-2255, June 2025.
Abstract Aims Few studies have examined the incidence, prevalence, survival rate and death risk for non‐rheumatic and rheumatic aortic stenosis (AS; RAS), aortic insufficiency (AR; RAR) and aortic stenosis with insufficiency (ASAR; RASAR). This study aims to identify the epidemiology of AS, AR, ASAR, RAS, RAR and RASAR.

Embryonic Development of the Bicuspid Aortic Valve

Journal of Cardiovascular Development and Disease, 2015
Bicuspid aortic valve (BAV) is the most common congenital valvular heart defect with an overall frequency of 0.5%–1.2%. BAVs result from abnormal aortic cusp formation during valvulogenesis, whereby adjacent cusps fuse into a single large cusp resulting in two, instead of the normal three, aortic cusps.

Bicuspid Aortic Valves With Different Spatial Orientations of the Leaflets Are Distinct Etiological Entities [PDF]

, 2009
ObjectivesThe aim of this study was to decide whether bicuspid aortic valves (BAVs) with fused right and noncoronary leaflets (R-N) and BAVs with fused right and left leaflets (R-L) have different etiologies or are the product of a single diathesis ...

Piccolo Device for Treating Patent Ductus Arteriosus Beyond Premature Newborn Patients, a Novel Experience in South America: A Retrospective Study

Health Science Reports, Volume 8, Issue 6, June 2025.
ABSTRACT Background and Aims Transcatheter closure of patent ductus arteriosus (PDA), particularly with the Amplatzer Piccolo Occluder, offers advantages over surgical closure, including better recovery and lower risk of complications. Although its smaller profile is preferred for neonatal endovascular closure, it may be used in patients of varying ...
