Background:Persistent ductus arteriosus is a common congenital cardiac disease. If it isn't diagnosed and treated on time, the patient will be suffered severe complication which can cause mortality. The surgery for ductus arteriosus closure is a treatment method which is being applied at many Surgery Center in our country. Objectives:This study aims to evaluate the results of transcatheter patent ductus arteriosus closure using amplatzer duct occluders in children admitted into national hospital of pediatrics. Subjects and method: A prospective study was carried out on 40 children with patent ductus arteriosus confirmed by echocardiography in National Hospital of Pediatrics from October 2005 to October 2006. Transcatheter closure by amplatzer was used in all patients. Changes in clinical, laboratory findings and particularly Echocardiography were obtained before and after treatment. Results: The mean age and weight of the patients were 44.86 \xb1 41.11 months and 12.44 \xb1 6.5 kg. Closure was successful in 38/40 patients (95%), complications occurred in one patient (2.5%), no death was occurred. The rate shunting was 15% after 1 day and 0% after 3 months. Conclusion: Transcatheter closure using the Amplatzer was an effective and safe treatment for patent ductus arteriosus in pediatric patients.

Percutaneous device closure of secundum atrial septal defect (ASD) has become a definite therapy in selected patients. However the more transcatheter device was implanted, the more complication was developed. Especially, the device embolization remains a major complication requiring immediate intervention. We report a case of a displaced ASD occluder in the ascending aorta. We were successfully removed the device through a total circulatory arrest and closed the ASD.

The Gerbode shunt, known as the left ventricle to the right atrial communication, is a rather rare finding, following surgical closure of septal defects. Even though the surgical closure is accepted as a treatment of choice, we report a successful percutaneous transcatheter closure of the Gerbode shunt in a 3-months old baby who weighed 3 kilograms.

A 77-year-old female patient underwent aortic valve replacement (AVR) with concomitant septal myectomy and tricuspid annuloplasty. Her symptoms did not improve after a successful operation. Echocardiogram demonstrated the presence of an iatrogenic ventricular septal defect (VSD). It was muscular in location and not the usual AVR with membraneous type of VSD, suggesting a complication from the myectomy. Percutaneous closure of the VSD remained the only feasible option due to her poor overall medical status. A 14-mm Amplazter VSD occluder was deployed successfully, by means of the trans-septal technique. She has improved very well postoperatively.

An atrial septal defect is the most common type of congenital heart disease among adults. Surgical repair or percutaneous closure of the defect is the treatment options. Even though percutaneous closure seems to be less risky than surgical repair, it may result in fatal complications like device embolism, cardiac perforation and tamponade. Herein we report a case of the embolism of a device into the pulmonary artery after one hour of percutaneous closure in which the embolized device was surgically removed and the defect was closed with a pericardial patch.

BACKGROUND AND OBJECTIVES: The rigid coupling between the delivery wire and the right atrial disk has been occasionally encountered during transcatheter closure of atrial septal defect (ASD). Therefore the device frequently makes a perpendicular angle, and the leading edge of left atrial disk slips through the defect and prolapses into right atrium (RA) before it is properly placed in the septum. The purpose of this study is to investigate relating factors to the need of technical modification in transcatheter closure of large ASD and to evaluate relevant morphologic characteristics of atrial septal rim in this situation. SUBJECTS AND METHODS: From July, 2003 to May, 2007, 312 patients underwent transcatheter occlusion of ASD with Amplatzer Septal Occluder(R) (ASO, AGA medical corporation, Golden Valley, MN, USA) at Yonsei Cardiovascular Center and among them 109 patients had large ASD (> or =25 mm) and these patients were enrolled in our study. Patients were divided into two groups according to the deploying methods of the device (Group I: standard method, Group II: modified methods). Assessments of the defects and its surrounding rims were made by echocardiography. RESULTS: There were no differences between 2 groups in age, body weight and height except for balloon-stretched diameter (stop-flow technique) and device size. Group II patients with modified methods showed larger balloon-stretched diameter and device size than group I patients with standard method. The mean length of anterosuperior (AS) rim in group II was significantly shorter than group I (p<0.05). As the size of the device used in procedure increased, there was a trend towards increase in the need of modified methods. CONCLUSION: This study shows that AS rim deficiency and the size of ASD may be the relating factors to the need of technical modification in transcatheter closure of ASD. Therefore, when the initial try with standard method is not successful in large ASD with deficient AS rim, we suggest that changing strategy of implantation may save time and efforts and possibly reduce the risk of complications associated with prolonged procedure.
