OBJECTIVE To apply three dimensional echocardiography to describe the geometric profile of the Amplatzer and Cardioseal occluders after deployment for closure of atrial septal defect. METHODS 20 patients (mean (SD) age, 14 (5) years) were enrolled for transcatheter closure of a secundum atrial septal defect with the Amplatzer occluder (10) or with the Cardioseal occluder (10). The two populat...

BACKGROUND Transcatheter occlusion of the patent ductus arteriosus (PDA) is a minimally invasive treatment. The appropriate device size is chosen based on the angiographic measurement of the PDA. The current study aimed to assess the relationship between the transthoracic echocardiographic (TTE) measurements of the PDA prior to the occlusion procedure and the actual size of the deployed device....

BACKGROUND The anatomy of septal defects can be complex and morphologically unpredictable. Balloon sizing of such defects may not be feasible, and an appropriately sized commercial occluder may not be available. Therefore, percutaneous transcatheter closure of such defects can be challenging because of an increased risk of complications. In this study, we have described the efficacy and safety ...

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 of 35 patients who underwent transthoracic device closure of an ASD with the very large domestic occluder (44-48 mm) at our institution were...

A 21-year-old male with a 27-mm atrial septal defect (ASD) underwent an uneventful percutaneous device closure using a 28-mm Ultrasept ASD Occluder with super-low profile (Cardia, Inc., USA) under transoesophageal echocardiography (TEE) guidance. We particularly favoured this kind of occluder device due to the possible future need for catheter atrial septostomy in such a young patient. The use ...

background: the ductus arteriosus connects the main pulmonary trunk to the descending aorta. the incidence of isolated patent ductus arteriosus (pda) in full-term infants is about 1 in 2000. the amplatzer ductal occluder (ado) is recommended for pdas with sizes larger than 2 mm. in this procedure, we must confirm the ado position in pda by aortogram from the arterial line. the purpose of this s...

Transcatheter device closure was performed under general anesthesia in all the patients. The interventional treatment modality was approved by the ethics committee of our hospital, and informed consent was obtained before the procedure. Femoral artery and vein was routinely punctured. Left ventricular angiography was performed at 60° left anterior oblique and 20° cranial tilt position. The entr...

A 21-year-old female patient was transferred to our hospital after being diagnosed with massive pulmonary thromboembolism (PTE). Three years prior to admission, she underwent transcatheter closure of the secundum ASD with a 33 mm CardioSEAL-StarFLEX occluder (NMT Medical, Boston, MA, USA). A year ago, she was involved in a car accident and sustained significant blunt chest trauma. Transthoracic...

The use of interatrial septal occluder devices is an efficacious and less invasive alternative to open heart surgery for the repair of atrial septal defects. These devices present significant risks including thrombus formation on the device and subsequent thromboembolic events. We present a case of a woman who presented with stroke-like symptoms five years after PFO closure. The patient was sub...

Six female patients aged from 19 to 73 years, with ostium secundum atrial septal defect underwent closure procedure with Amplatzer septal occluder device. Three-dimensional Echocardiography (3D-TEE) was done during the procedure or one day after the procedure. 3D-TEE provides incremental value over Two- dimensional trans-esophageal echocardiography in measuring Amplatzer septal occluder disc si...
