Atrial Septal Defects [PDF]

open access: yes, 2014
Atrial septal defects are the third most common type of congenital heart disease. Included in this group of malformations are several types of atrial communications that allow shunting of blood between the systemic and the pulmonary circulations.

Motion estimation of vortical blood flow within the right atrium in a patient with atrial septal defect [PDF]

open access: yes, 2007
Copyright © 2007 IEEEPatients with an atrial septal defect (ASD) have a left to right shunt with associated complications. Currently, various imaging modalities, including echocardiography and invasive cardiac catheterization, are utilized in the ...

Rescue atrial septal defect closure with the new GORE® cardioform atrial septal defect occluder

open access: yesAnnals of Pediatric Cardiology, 2022
Atrioventricular block (AVB) is an infrequent but life-threatening complication of transcatheter closure of atrial septal defect (ASD), accounting for 0.1%–6.2% of cases in large series.

Transcatheter closure of Ventricular Septal defects in Malta : initial experience [PDF]

open access: yes, 2005
Ventricular septal defects (VSD) consist of deficiencies of the wall separating the two ventricles. VSDs are the commonest congenital cardiac defects. Small VSDs rarely require intervention, however, larger defects cause ventricular volume overload with ...

Virtual left atrial appendage occlusion in paroxysmal atrial fibrillation during sinus rhythm predicts variable reductions in blood stasis

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend Stasis before and after left atrial appendage occlusion (LAAO) in participants with high stasis and low stasis. Stasis is predominantly located in LAA and reduced after LAAO. But in the participant with high stasis, stasis remains close to the occlusion site, indicating a potential risk for device related thrombi.

Midterm follow-up of transthoracic device closure of an atrial septal defect using the very large domestic occluder (44–48 mm), a single Chinese cardiac center experience

open access: yesJournal of Cardiothoracic Surgery, 2017
Background The purpose of this study was to outline the midterm follow-up results and complications in patients who underwent transthoracic device closure of an atrial septal defect (ASD) with the very large domestic occluder (44–48 mm). Methods The data

Fabrication and characterization of chitosan nanoparticles and collagen-loaded polyurethane nanocomposite membrane coated with heparin for atrial septal defect (ASD) closure [PDF]

open access: yes, 2017
Atrial septal defect (ASD) constitutes 30–40% of all congenital heart diseases in adults. The most common complications in the treatment of ASD are embolization of the device and thrombosis formation.

Horizontal Heart Orientation as a Mechanistic Contributor to Platypnea–Orthodeoxia Syndrome in Patent Foramen Ovale

open access: yesClinical Case Reports, Volume 14, Issue 5, May 2026.
ABSTRACT Altered cardiac orientation in the presence of a patent foramen ovale (PFO) can contribute to platypnea–orthodeoxia syndrome (POS) and unexplained hypoxemia. In such cases, consideration of PFO closure may lead to significant clinical improvement.
