Abstract

Background

Pulmonary atresia and intact ventricular septum is a complex congenital heart disease with great morphological variability. Approximately two-thirds of patients may be suitable for transcatheter pulmonary valvotomy. We reviewed our experience in the use of two different percutaneous approaches to evaluate the impact on fluoroscopy time and morbidity of a new technique to perform transcatheter radiofrequency perforation and valvotomy in newborns with pulmonary atresia and intact ventricular septum.

Methods and Results

In all, 31 patients underwent radiofrequency perforation of the pulmonary valve. The first 14 infants were treated using a 5 French Judkins right coronary catheter, which was manoeuvred directly underneath the atretic pulmonary valve (Group A). The others were treated using a telescopic system consisting of Northstar Lumax Flex and White Lumax Guiding Catheters (Cook; Group B). In both groups, after radiofrequency perforation of the pulmonary valve, a 0.014-inch superfloppy guidewire was advanced into the descending aorta and balloon dilations were performed. Required fluoroscopy time was significantly lower in Group B (48.5 ± 28.1 versus 24.9 ± 14.4 minutes, respectively; p < 0.01). A higher incidence of unfavourable events including the need for early surgery was found in Group A.

Conclusion

In our experience, telescopic catheter proved to be a valid option able to decrease the fluoroscopy time of percutaneous radiofrequency perforation of pulmonary valve and consequently patients’ exposure to procedure-related risks.
