4D Flow has been used to study blood flow patterns, mainly in the aorta. We performed a flow pattern analysis in the Pulmonary Artery (PA). 4D Flow depicted complex flow patterns in the PA, revealing two vortices in the main PA and one in the right PA in healthy subjects. Abnormal blood flow patterns were seen in patients with different Congenital Heart Diseases (CHD), revealing complex hemodynamics in the pulmonary circuit. Knowledge of abnormal flow patterns in the PA in patients with CHD has the potential to contribute to improve current surgical interventions in this group of patients.
