Introduction:

The interventional catheterization corrects complex heart diseases, and the Amplatzer device is the most widely used and is available in Cuba.

Objective:

To assess the interventional catheterization with Amplatzer device in the ostium secundum atrial septal closure.

Methods:

Longitudinal and prospective evaluation study in 92 patients. The closure of the communication by Amplatzer catheterization was performed in the "William Soler” Pediatric Cardiocenter of (2010-2016). Demographic and echocardiographic (transthoracic and transesophageal) variables were used before, during, and at the year of the catheterization. Complications were observed. Clinical and echocardiographic assessment was made a year after catheterism. The patients who underwent the procedure in 2016 were evaluated at 6 months.

Results:

Significant differences were found in the sex (p< 0.05): Female 64.1% with homogeneity of the age (p= 0.244): average 9.8 years ( 5 standard deviations. Pre-catheterism: 28.3% were malnourished and 17.4% thin; post-catheterism: malnutrition improved significantly (p= 0.000): 9.8% malnourished and 8.7% thin. The average diameter of the defect by transcatheter echocardiography was significant (p= 0.000). Transcatheter: 98.9%: with default closure, 16.3% with tricuspid insufficiency and 4.3% with mitral regurgitation. Post-catheterism: 98.9% with Amplatzer device correctly positioned. There were immediate complications in 8.7% (arrhythmia, pericardial effusion, and embolization). A year after, small residual short circuit was detected (n= 1), and atrioventricular valve regurgitation (n= 3). The evolution was satisfactory (n= 91).

Conclusions:

The evolution of ostium secundum atrial septal defect´s closure with Amplatzer device is satisfactory and improves malnutrition.
