Abstract
A case of pulmonary atresia with ventricular septal defect is reported in which a communication was established between the right ventricle and the hypoplastic pulmonary artery by intervention, despite muscular atresia of the right ventricular outflow tract. The atresia was perforated with a special designed radiofrequency catheter (Osypka). After the creation of a canal within the muscular atresia, balloon dilatation (diameters 2, 3.5, and 7.2 mm) was performed. Arterial oxygen saturation increased from 64% to 78%. Lateral deviation of the radiofrequency catheter resulting in a lateral perforation of the atretic muscular infundibulum was well tolerated without later sequelae. Early restenosis within two weeks necessitated the implantation of a stent within the "recanalised" atresia resulting in an increased anterograde flow to the pulmonary artery. This case shows that "recanalisation" of muscular atresia of the pulmonary artery by radiofrequency is a promising technique. Additionally, stent implantation into the infundibulum to prevent restenosis is a first step to interventional right ventricular outflow tract reconstruction.Keywords
