Multifunctional Device (Konar-MF-VSD) for Percutaneous Closure of Ventricular Septal Defects Cases Report

A ventricular septal defect (VSD) is communication between both ventricles. There are diferent types of VSDs based on anatomy. At the National Institute of Child Health San Borja (INSNSB) Lima – Peru the treatment carried out in the hospital was surgical. "Since the beginning of 2023, the multifunctional device (KONAR-MF-VSD) was approved for commercialization in Peru, and its use in the hospital began in 2024." We present eight clinical cases in which patients were successfully treated using the new multifunctional device (KONAR-MF-VSD). No complications occurred during the peri-operative period or the first month of follow-up. Before 2024, the hospital relied exclusively on surgical closure for VSDs. The introduction of the KONAR-MF-VSD device was motivated by its flexibility, reduced radial force, and adaptability to various VSD morphologies, enhancing procedural success rates. Percutaneous closure of muscular and perimembranous ventricular septal defect with the KONAR – MF- VSD device can be performed both antegrade and retrograde without complications.
