Objective: Transcatheter closure of medium and large ventricular septal defects (VSDs) in young children is limited due to the use of over-sized devices that can cause hemodynamic instability and arrhythmia. In this study, we aimed to retrospectively evaluate the safety and efficacy of the device in the mid-term in children weighing less than 10 kg whose transcatheter VSD was closed only with the Konar-MFO device.
Patients And Methods: Among 70 children whose transcatheter VSD was closed between January 2018 and January 2023, 23 patients weighing less than 10 kg were included in the study.
