    The KONAR-MF™ device is an effective option for percutaneous closure of patent ductus arteriosus (PDA) in patients with complex anatomies.

    Seventeen patients were analyzed, with a median age of 1 year and median weight of 11 kg, highlighting its use in underweight individuals.

  • 3

    Functional class III was present in 58.8% of patients, indicating significant clinical symptoms prior to the procedure.

  • 4

    A residual shunt was detected in 23.5% of patients post-procedure, but all resolved by the 6-month follow-up.

    The study suggests that the KONAR-MF™ device may be a valid alternative for PDA closure, especially in patients weighing less than 6 kg.
