The non-circular shape of FloWatch®-PAB prevents the need for pulmonary artery reconstruction after banding.Computational fluid dynamics and clinical correlations

Abstract

The non-circular shape of FloWatch-PAB can replace conventional circular banding with the following advantages: (a) the pressure gradient will remain essentially the same as for conventional circular banding for any given cross-section, but with significantly smaller reduction of PA perimeter; and (b) PA reconstruction at the time of de-banding for intra-cardiac repair can be avoided.
