OBJECTIVE: To evaluate the feasibility, efficacy, and safety of a fully biodegradable poly lactic acid (PLA)-based occluder for atrial septal defect (ASD) closure in an animal model. METHODS: ASDs, approximately 12-mm in diameter, were generated in sheep (n = 18) by needle puncture and balloon dilatation. For ASD closure, occluders were implanted by percutaneous transcatheter approach under echocardiographic guidance. Outcomes were evaluated by transthoracic echocardiography, electrocardiography, blood testing, and histology within the follow-up period ranging from 1 month to 2 years...

Atrial septal defect (ASD) is one of the two most common congenital heart diseases in children and adult. After the application of catheter intervention for ASD, this became an alternative treatment other than surgery from late 1990. In 2001, the procedure was further approved by the US Food and Drug Administration (FDA), and become the first choice for most cases of secundum type of ASD worldwide. The success rate is more than 98% in literature reviews, with low complication rates in percutaneous ASD closure...

Some studies have been showed that electromechanical delay, which may pose an increased tendency to atrial fibrillation, may prolong in patients with various clinical conditions. In addition, the electromechanical delay in patients with secundum type atrial septal defect (ASD) compared to healthy people have been reported previously. Therefore, in the present study, we prospectively evaluated the mid-term and long-term effects of the transcatheter closure of secundum type ASD on the lateral atrial conduction time (PA), septal PA, tricuspid PA, left and right intra-atrial electromechanical delay (ILeft-EMD and IRight-EMD, respectively) and inter-atrial electromechanical delay (IA-EMD) measured by means of Doppler echocardiography...

A 75 year-old female with symptomatic severe mitral regurgitation of a bio-prosthetic valve secondary to valve leaflet perforation due to endocarditis underwent a mitral valve in valve replacement in an existing Hancock 27 mm valve using a trans-femoral/trans-septal approach. The procedure was complicated by an iatrogenic atrial septal defect post trans-septal puncture causing a severe right-to-left shunt due, possibly, to the combination of severe pulmonary hypertension and moderate tricuspid regurgitation the patient had suffered from at base line...

Ischaemic stroke is among the leading causes of disability and death. Despite extensive vascular, cardiac and serological evaluations, the cause remains unknown in 20%-40% of patients. These are classified as cryptogenic stroke. Paradoxical embolism is one of the many causes of cryptogenic stroke. The term paradoxical embolism is used to describe an embolus of venous origin entering the systemic circulation through a patent foramen ovale (PFO), atrial septal defect (ASD), ventricular septal defect or extracardiac communication such as pulmonary arteriovenous malformation...

A 63-year-old man with cirrhosis, hepatocellular carcinoma, and coagulopathy was diagnosed with a sinus venosus atrial septal defect (ASD) and partial anomalous pulmonary venous return (PAPVR) of the right upper pulmonary vein (RUPV). Transcatheter repair by positioning a stent graft in the superior vena cava was planned. Based on three-dimensional (3D) reconstruction of gated cardiac CTA, a 28 mm × 7 cm Endurant II® aortic extension stent graft (Medtronic, MN) was chosen. A 3D model printed from the CTA was used to simulate device deployment, demonstrating successful exclusion of the sinus venosus ASD with return of the RUPV to the left atrium (LA)...

This review discusses the management of ventricular septal defects (VSDs) and atrioventricular septal defects (AVSDs). There are several types of VSDs: perimembranous, supracristal, atrioventricular septal, and muscular. The indications for closure are moderate to large VSDs with enlarged left atrium and left ventricle or elevated pulmonary artery pressure (or both) and a pulmonary-to-systemic flow ratio greater than 2:1. Surgical closure is recommended for large perimembranous VSDs, supracristal VSDs, and VSDs with aortic valve prolapse...

Introduction: Atrial septal defect (ASD) is the most common congenital cardiac anomaly diagnosed in adults. It often remains asymptomatic until the fourth or fifth decade of life. Significant left-to-right interatrial shunting is associated with the risk of heart failure, pulmonary hypertension and atrial fibrillation. Percutaneous ASD closure is a recognized method of treatment. Aim: To evaluate the clinical outcomes and physical capacity in patients undergoing transcatheter closure of ostium secundum ASD...

The authors present the case of a 41-year-old woman, who presented with moderate pericardial effusion and bilateral pleural effusion 11 months following a secundum atrial septal defect closure with an Amplatzer septal occluder (ASO) device. The acute presentation responded well to diuretics and a short course of corticosteroid therapy. The patient, however, continued to experience pleuritic chest pain and a recurrence of pericardial effusion a month later. The patient showed significant symptomatic improvement with a 2-month course of down-titrating prednisolone...

Background Percutaneous device closure of an ostium secundum atrial septal defect is associated with excellent outcomes and cosmetic results but at the cost of occasional serious and sometimes fatal complications as well as lifelong follow-up. Surgical intervention is required in cases of device-related complications, which carries a slightly higher risk compared to primary closure of an atrial septal defect. We present a surgical perspective of device closure of atrial septal defect. Methods Our database was searched over 4 years for complications related to percutaneous device closure of atrial septal defect, which required surgical retrieval of the device and closure of the defect...
