Abstract
The aim of this publication is to report the short and mid-term results of the closure of perimembranous and muscular Ventricular Septal Defect (VSDs) with the novel device, Konar-Multifunctional Occluder (MFO).
Introduction: The endovascular closure of Ventricu- lar Septal Defect (VSD) is a well-established procedure. The Konar Multifunctional occluder (MFO) allows clo- sure of large VSDs in an antegrade or retrograde way.
Materials and Method: Since October 2017, the VSD closures were performed in 17 patients with MFO de- vice, including 3 patients weighing less than 5 kg with Associated Complex Congenital Heart Diseases. The Transthoracic Echocardiography (TTE) measurements were as follow: Left orifice: mean of 7.71 mm ±SD (4 to 12.3 mm); Right orifice: mean of 4.69 mm ±SD (2.8 to 7.8 mm); Length: mean of 5.75 mm ±SD (3 to 9.7 mm).
Results: From the scope of 17 patients, 16 procedures were successful and only 1 failed. The mean follow-up was 5.3 months (1 to 11 month). There were no major complications such as complete AV block, hemolysis, etc. No residual shunt was showed in the mid-term fol- low-up. 2 patients less than 5 kg died afterwards: 1 due
to sepsis and the other one after the reoperation of se- vere restenosis of the pulmonary veins.
Conclusions: VSD closure with the Konar-MF occlud- er is feasible for both congenital and residual post- operative VSDs. It offers a vast variety of options by allowing different approaches to the VSD occlusion, (antegrade, retrograde and even through the foramen ovale), that had greatly simplified the procedure, giv- ing the device a very substantial advantage, including the closure of large defects in low weight patients.

Introduction
Ventricular Septal Defects (VSDs) is the second most frequent congenital heart disease. The inci- dence of VSD is between 1.5 and 3.5/1000 in live birth and 4.5 to 7/1000 in premature babies1. The peri- membranous VSD makes 70% of the VSD2 cases.
