Potts shunt for the treatment of suprasystemic pulmonary artery hypertension: geometric multiscale and reduced models

The Potts shunt (PS) is an anastomosis that connects the left pulmonary artery to the descending aorta. It has been proposed as a potential palliative treatment of drug-resistant suprasystemic pulmonary arterial hypertension (PAH). We propose a geometric multiscale (GMS) model to study the changes in both local and global haemodynamics induced by the Potts shunt. GMS model parameters are estimated to reproduce the pre-operative measurements of a patient with suprasystemic idiopathic PAH, who received a PS percutaneously. Model validation is performed by comparison of model output against the post-operative measurements.
