This research aims to evaluate the feasibility and safety of a new system for closing large atrial septal defects.
Used a 10 Fr version of the ASD occlusion system with two umbrellas for closure.
Five adult patients with defects measuring 26-35 mm were treated and closely monitored post-procedure.
Procedures involved repetitive positioning and adjustments of the umbrellas to anchor them correctly.
Closure was successful in all five patients, with symptoms resolved at 7-10 months follow-up.
Surgical interventions were required for complications, including prosthesis dislodgement in two patients.
One patient experienced an umbrella-arm fracture four months post-implantation.
