Abstract:
BACKGROUND AND OBJECTIVES: We report our initial experience with percutaneous transvenous closure of atrial septal defects (ASD). MATERIALS AND METHOD: Between September 1997 and May 2000, we attempted transcatheter closure of ASD in 18 patients using CardioSEALTM (8), STARFlexTM (4) and Amplatzer septal occluder (6). The ages of patients ranged from 4.5-64.8 (mean 32.8) years, body weight ranging from 16-76 (mean 51) kg, Qp/Qs ratio from 1.3-3.4 (mean 2.2). RESULTS: Embolization of device occurred in two patients; right pulmonary artery in one and left atrium in the other. In one patient, the device slipped into the right atrium before detachment. After retrieval of the device, the defect seemed too large for transcatheter closure. There were no other complications apart from a transient aggravation of pre-existing atrial premature beats in two patients. There was no significant size difference between the data measured by transthoracic and transesophageal echocardiography. The stretched ASD diameter was larger (5.1 3.2 mm) than the size measured by transesophageal echocardiography. In the remaining 15 patients, complete closure of defects was confirmed by transthoracic echocardiography on the 1 day or 1 month follow-up. During the same period, transcatheter closure of patent foramen ovale(PFO) was also attempted in 7 patients with stroke. The guidewire could not be passed in 2 of the patients. In the other 5 patients, transcatheter closure was successfully performed without any problems. Though the follow-up period may have been short, no patients were found with further stroke attack. CONCLUSION: Transcatheter closure of ASD can be performed with high efficiency and safety if patient selection is adequate. The indication for ASD closure can be extended to patients with larger defects. Transcatheter closure of PFO is an easy and safe procedure, but the indications of PFO closure in patients with stroke is still unclear. Further evaluation is necessary for long-term results.
