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: 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 devic...

An atrial septal aneurysm may be associated with a patent foramen ovale. When paradoxical emboli result, the shunt must be closed and the atrial septal aneurysm excised. A reversed buttoned occluder device was successfully used for the transcatheter treatment of this condition.

OBJECTIVES The aim of this study is to evaluate our clinical experience using an Amplatzer septal occluder for catheter closure of a secundum atrial septal defect under transthoracic echocardiography guidance without general anaesthesia. METHODS Patients eligible for transcatheter atrial septal defect closure were selected using transthoracic echocardiography. The largest defect diameter meas...

BACKGROUND Recent advances in miniaturization of phased-array and mechanical ultrasound devices have resulted in exploration of alternative approaches to cardiac and vascular imaging in the form of transesophageal or intravascular imaging. Preliminary efforts in adapting phased-array endoscopes designed for transesophageal use to a transvascular approach have used full-sized phased-array device...

INTRODUCTION The device closure of atrial septal defects has evolved over the years. In the early days of transcatheter occlusion, balloon sizing was used to choose an appropriate sized device. We postulate that balloon sizing does not value-add to the procedure and is unnecessary. MATERIALS AND METHODS Patients who had balloon sizing, with (Group 1, n = 38) or without (Group 2, n = 21) atria...

Aorto-left atrial fistulas are rare. We describe the case of a patient in whom transcatheter closure of an aorto-left atrial fistula was carried out using an Amplatzer septal occluder. The patient had previously undergone cardiac surgery twice because of a recurrent left atrial myxoma. Closure of this type of fistula using a transcatheter device should be considered when the location and size o...

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...
