Fusion imaging for guidance of pulmonary arteriovenous malformation embolisation with minimal radiation and contrast exposure

Catalina Vargas-Acevedo, Ernesto Mejia, Jenny E. Zablah, Gareth J. MorganUniversity of Colorado and Children’s Hospital Colorado.United States Cardiology in the YoungCardiol Young 2024; DOI: 10.1017/S1047951124000349 AbstractHereditary haemorrhagic telangiectasia is an inherited disorder characterised by vascular dysplasia that leads to the development of arteriovenous malformations. Pulmonary arteriovenous malformations occur in approximately 30% of patients with haemorrhagic telangiectasia.

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

Pregnancy and delivery after percutaneous embolization with a combination of microvascular plugs and hydrogel-coated coils for unilateral diffuse pulmonary arteriovenous malformations: a case report

Kayo Ogino, Tomohiro Hayashi, Kenji Waki, Masanobu OhyaKurashiki Central Hospital.Japan European Heart Journal Case ReportsEur Heart J Case Rep 2023; 7:DOI: 10.1093/ehjcr/ytad468 AbstractBackground: Pulmonary arteriovenous malformations (PAVMs) are abnormal communications between the pulmonary arteries and veins; right-to-left shunts can cause hypoxaemia, emboli to systemic circulation, and brain abscesses. Cyanosis during pregnancy may increase the probability of premature
