TCTAP A-077 Intracardiac Ultrasound Assistance Method in ASD Closure Procedure

Percutaneous implantation of an ASD occluder with intracardiac ultrasound

[Iatrogenic atrial septal defect: intracardiac ultrasound-guided percutaneous closure].

Atrial septal defect (ASD) is a rare complication after cardiac surgery, usually related to atrial septostomy for valve repair or replacement. Repair has traditionally required new surgery, with greater risk for the patient. We describe the case of a patient with iatrogenic ASD after surgery for mitral valve repair, who was successfully treated by percutaneous implantation of an Amplatzer devic...

Concomitant radiofrequency Maze III – procedure and surgical ASD closure in adults

Methods 84 adult patients (mean age 40,8 ± 7,2 years) with ASD and different forms of AF were operated between 20052012 with next forms of AF: paroxysmal – 48, persistent – 26, long persistent – 10 patients. We performed radiofrequency “maze III” procedure and then ASD closure in CPB. Mean CPB-time was 64±18 min. Lines of ablation were performed point-by-point applications with exposition of 15...

Experimental ASD closure using autologous cell-seeded interventional closure devices.

OBJECTIVE Atrial septal defect (ASD) occluders are permanent implants in paediatric cardiology which serve as mechanical shields until complete overgrowth and incorporation of the occluding device by autologous tissue has occurred. Thereafter, the foreign body material making up the device is dispensable and bears potential long-term adverse effects. Rapid, firm and complete incorporation into ...

Intravascular and Intracardiac Ultrasound Imaging

C onsiderable attention is currently being focused on the development of intravascular and intracardiac ultrasound imaging.1-4 Variously termed as "ultrasound angioscopy," "intravascular ultrasound imaging," or "intraluminal ultrasound imaging," this technique basically refers to the imaging modality of visualizing blood vessels and cardiac structures by an ultrasound transducer placed at the t...
