In vivo hepatic flow distribution by computational fluid dynamics can predict pulmonary flow distribution in patients with Fontan circulation

Petter Frieberg, Pia Sjöberg, Erik Hedström, Marcus Carlsson, Petru LiubaLund University and Skåne University Hospital.Sweden Scientific ReportsSci Rep 2023; 13:DOI: 10.1038/s41598-023-45396-6 AbstractIn Fontan patients, a lung deprived of hepatic blood may develop pulmonary arterio-venous malformations (PAVMs) resulting in shunting, reduced pulmonary vascular resistance (PVR) and decreased oxygenation. To provide guidance for corrective invasive interventions, we aimed
