Introduction: Atrial septal defects (ASD) are congenital cardiac defects, that result in a communication between the left and right atria, and account for 6 - 10% of all congenital hearts disease (CHD). Transcatheter closure of secundum ASD now widely used with global acceptance, closure of atrial septal defect with complex anatomy remain the challenging issue required careful planning and special technique.

Aim of the Study: To prospectively study the outcomes and techniques of transcatheter closure of complex Atrial septal defects.

Methods: An eighty-eight patients with complex atrial septal defects included in a prospective single-center study, from January 2018 till February 2019, at Ibn Albitar center for cardiac surgery, Baghdad, Iraq. Complex atrial septal defect was predefined and inclusion and exclusion criteria are included. All the patients had meticulous echocardiography imaging beforehand. Modifications of the conventional techniques were allowed on a case per case basis according to operator preference.

Results: Out of the 88 patients enrolled, 80 patients had successful device closure (success rate 90.9%) despite challenging anatomy. The closure was failed in 8 cases (9.1%), all of them had a deficient/absent rim, most commonly inferior rim. The most common method used was a conventional technique with or without modifications, followed by dilator assisted method. With no recorded major complication.

Conclusion: Transcatheter closure is safe and feasible in anatomically complex Secundum atrial septal defect. Careful case selection, scrupulous imaging protocol, and expertise in modified techniques are mandatory for successful outcomes.
