Abstract
Background Percutaneous pulmonary valve implantation (PPVI) requires the positioning of a stiff guidewire into one of the pulmonary branch arteries. An infrequent but commonly known complication is the “jailing” of one of the pulmonary branch arteries. However, even without apparent “jailing” of one of the pulmonary branch arteries, we suspect that the technique of stent placements often has an effect on the pulmonary perfusion ratio. The aim of this study was to assess the changes of the pulmonary perfusion ratio and their predictors after PPVI.
Highlights
Percutaneous pulmonary valve implantation (PPVI) requires the positioning of a stiff guidewire into one of the pulmonary branch arteries
A change of more than +/- 10% in percent right pulmonary blood (RPA) flow was considered as a significant change in pulmonary perfusion ratio
The pulmonary perfusion ratio changed in 17 % of patients significantly by 15 ± 4 %
