Pre- an and immediate post-interventional results after bilateral (b) endoluminal (e) pulmonary artery banding of Patient #1. Transcatheter placed bilateral pulmonary flow restrictors resulted in an immediate increase of the pulmonary artery pressure, while the ratio of the systolic pulmonary artery pressure to the left ventricular systolic pressure increased from 0.41 to 0.73. Note, that the ventricular septum shifted from right to left with functional improvement of the left ventricular function.
