Japanese Study Links Main Pulmonary Artery Dilation with Worse Outcomes in Pediatric PAH
Pulmonary artery dilation speeds up the progression of pediatric idiopathic and heritable pulmonary arterial hypertension (PAH), a Japanese study shows. Dilation of the main pulmonary artery (MPA) and narrowing of the peripheral pulmonary artery are both characteristic of PAH. Previous studies have shown that MPA dilation is linked to higher pulmonary artery…
