Transcatheter closure of congenital Gerbode‐type ventricular septal defect using the new multifunctional occluder device

Abstract

The KONAR‐Multifunctional™ VSD Occluder (MFO) (Lifetech) is one of the most recent additions to the armamentarium of transcatheter therapies. The device offers superior technical features and experienced interventionists having been using it in risky and complex anatomies. Herein, we report the first use of the MFO device to close a congenital Gerbode‐type perimembranous ventricular septal defect in an 18‐year‐old girl. The device was retrogradely implanted into proper position under ultrasound and fluoroscopic guidance. Immediate and 12‐month‐follow‐up confirmed successful outcomes with complete shunt closure and resolution of tricuspid regurgitation.

Transcatheter Closure of Perimembranous Ventricular Septal Defects Including Multifenestrated and Gerbode-Type Defects Using the Lifetech Konar Device

“…Due to the plug softness and its design on the left side, the occluder fits very well within the aneurysm reducing the risk of residual shunt. It also seems really appropriate in cases of multiple exits on the right side or multifenestrated defects including the Gerbode-type VSD [1,[3][4][5][6][7][8][9][10], which is not a limitation although only one exit is crossed by the device. In this setting, to obtain full occlusion was more complex but possible, and this was noticed in half of our patients, even if two patients received a second occluder, as already reported [9].…”

Transcatheter closure of an acquired post-operative aorta to right ventricle shunt in a child with complex univentricular heart

“…[1][2][3][4][5][6] The recently introduced KONAR-MFO has been smartly designed, combining technical features of previous occluder devices, to tackle encountered difficulties. [7][8][9] Emerging reports are consecutively positive and clinical applications have been mainly limited to ventricular septal defects closure. 9 This is the first use of the KONAR-MFO to percutaneously treat an iatrogenic aorta to right ventricle shunt occurring in a complex child following intracardiac repair.…”
