Percutaneous closure by interventional catheterization of atrial septal defect is currently considered to be the technique of first-choice closure subject to meeting the recommended criteria, anatomical and hemodynamic.

The objective of this work is to assess the effectiveness and safety of this technique.

Our retrospective study is carried out in the cardiology department of Ibn Rochd hospital, including 24 patients who benefit from percutaneous closure by catheterization intervention of their CIA.

Our series notes a female predominance (17 F and 7 M), the average age at the time of the intervention was 7 years (3 years is 17), the average weight is 27 kg (10–80 kg), the discovery of a heart murmur and pneumonia has repetitions are the 2 most frequent reasons for consultation. The TTE is the key examination that allowed the diagnosis positive of the CIA, to define its denials, the signs of repercussion and especially to establish with precision the anatomical edges of the defect and establish the indication for closure by interventional catheterization.

Transesophageal and transthoracic doppler echocardiography are a useful complement during the intervention which was of great help for the success of the installation of the prosthesis. The choice of the prosthesis is made according to the size of the CIA. All our patients are followed, their clinical examination finds a good evolution with improvement of the functional signs and good weight gain. Echocardiography is satisfactory (prosthesis in place and absence of shunt) in 23 cases of CIA or 95.8%, and showed a minimal residual shunt in only 1 case or 4.1%. No late complications are occurred over a 36-month follow-up.

Percutaneous closure of CIA is a safe and effective method; the selection of candidate patients is essential according to the type of CIA and its anatomy...
