Immediate and short term outcome post VSD closure using nitocclud PFM coil, a single center experience

Abstract

ObjectivesWe sought to study the immediate and short term outcome post VSD closure using nitocclud PFM coil to document the safety and efficacy of the procedure. Patients and MethodsThe study included 16 patients with perimembranous subaortic VSD who were scheduled for elective trans catheter VSD closure using nitocclud PFM coil in the period from May 2014 to July 2016. All patients underwent full clinical examination, ECG and full echocardiographic study immediately before trans catheter closure as well as 24 h, 1 month and every 6 months after the procedure. Any intra or post procedural complications and their respective management were recorded. ResultsThe mean age of the study subjects was 7.4 years. The distance between the defect and the aortic valve was an average of 5.4 ± 1.8 mm, and the left ventricular opening averaged 10.6 ± 3.7 mm. immediate closure of the VSD was achieved in 25% of the cases. This percentage increased to 75% after 1 month. Intravascular hemolysis developed 3 days after the procedure in one patient with a residual shunt and was successfully managed by a PDA Amplatzer occluder device implanted in the residual defect. Three children had transient self-limiting bradycardia and junctional rhythm during the procedure. ConclusionVSD closure using nitocclud PFM coil is safe and effective in selected patients. However, we report hemolysis in one patient with residual shunt which needs careful follow up and prompt management.
