چکیده
OBJECTIVE To evaluate the safety and efficacy of transcatheter closure of secundum atrial septal defects and fenestrated Fontan with the Amplatzer septal occluder. METHODS Fifteen consecutive patients, with a significant interatrial communications, were considered for the procedure; four patients with defects that were too large or with deficient margins were excluded after initial transesophageal echocardiography. RESULTS Eleven procedures were performed in 11 patients (10 atrial septal defects and 1 fenestrated Fontan) aged 9 to 38 years, mean 17.7 +/- 9 years; body weight 30 to 87 kg, mean 51.4 +/- 16. The stretched balloon diameter of the defects ranged from 8 to 28 mm, mean 18.8 +/- 6.9; the diameter of the devices ranged from 10 to 30 mm, mean 20.8 +/- 6. Immediate total occlusion rate was 18.1%, rising to 63.6% after 24 hours. Total occlusion rate at one month reached 100%. Severe transient sinus bradycardia in one (9%) was the only complications. At follow-up (10 to 26 months, mean 13.2 +/- 5.0) all patients remain asymptomatic with no residual shunt. CONCLUSIONS The Amplatzer septal occluder is very efficient and offered interventional interatrial communications closure in 100% of our group of consecutive patients with excellent intermediate results.

Objective: To assess the short-term outcome following transcatheter closure of secundum atrial septal defect (ASD) in our hospital. Patients and Methods: Between June 2000 and November 2001, 20 patients diagnosed as secundum atrial septal defects underwent transcatheter closure of their defects using the Amplatzer septal occluder (ASO) device. Indications for 18 patients were larger atrial sept...

An alternative to the surgical repair of secundum type atrial septal defects (ASD) and of patent ductus arteriosus (PDA) is transcatheter closure. However, there is limited information about the efficacy of using percutaneous devices to close multiple ASDs. An 8-year-old female patient was admitted to our hospital with a cardiac murmur. A large secundum multi-fenestrated ASD (17 mm, 4.5 mm, 3 m...

BACKGROUND Transcatheter closure of ostium secundum atrial septum defect (ASDII) using the new self-centering occluder, Amplatzer Septal Occluder (ASO), has been well developed in recent years. We describe the importance and role of transesophageal echocardiography (TEE) in the selection and closure of such defects. METHODS Thirty patients referred for transcatheter closure of ASDII by ASO we...
متن کاملSurgical Management for Complications during Closure of Atrial Septal Defect with Amplatzer Device.
BACKGROUND Transcatheter closure of secundum type atrial septal defect (ASD) has become a standard procedure in most medical centers. Although the procedure is invasive and has a shorter recovery duration and a lower complication rate compared with surgery, it is not risk-free. In this retrospective chart review case series, we report our experience of management of complications after placemen...
