Patient-specific evaluation of pulmonary vascular resistances after corrected transposition of the great arteries

Patients with corrected transposition of the great arteries (TGA) can develop unilateral pulmonary stenosis as a long-term complication of the surgical correction. It is assumed that pulmonary vascular resistances (PVR) in these patients remodel to allow the lung in the stenotic side to be correctly perfused. A patient-specific computational model was developed using MR and flow patients’ data to better understand this phenomenon and to evaluate the fluid dynamics in this class of patients.
