Objectives:
To study the immediate, short, and intermediate results of transcatheter closure of secondum-type atrial septal defect using Amplatzer septal occluder devices (TCAA) in terms of clinical symptoms and residual lesions and shunts determined by transthoracic two-dimensional (TTE) and three-dimensional echocardiography (TDE).
Material And Method:
Thirty-six patients, who underwent successful TCAA at the Chest Disease Institute between August 2002 and August 2007 and were followed up clinically, by TTE and TDE at day 1-3, 4-6 months, and 1-year post TCAA, were analyzed.
Results:
TCAA was performed in 75 patients during the study period. Of these, 36 patients were completely followed-up. There were 92% female with a mean age of 40 +/- 16 yrs (range 19 to 65) and the mean of maximal size of ASD secondum determined by TTE, transesophageal echocardiography (TTE) and balloon sizing or balloon stretched diameter (BSD)was 18.9 +/- 4.7 mm (range 10-30), 22.6 +/- 5.3 mm (rang 10-32), and 24.3 +/- 5.3 mm (range 12-34) respectively. The size of ASOD was 26.4 +/- 4.9 mm (range 12-34). Fluoroscopic time was 16.4 +/- 7.1 min (range 6.7-35.6). The success rate of TCAA was 84%. No major complications and deaths were found. All of those with successful TCAA apparently improved their functional class. All of them showed complete ASD closure and yet 12 (31%) had Qp/Qs > or = 1.5 at year one.
Conclusion:
TCAA is safe and effective and had resulted in clinical improvement, complete closure of secondum ASD, and good immediate, short, and intermediate outcomes with fewer complications.
