Abstract
Increased pulmonary artery systolic pressure (PASP) with downstream consequences on the right ventricle (RV) is the shared hallmark of the various forms of pulmonary hypertension (PH). The underlying pathophysiology of elevated PASP varies greatly between PH classification groups. Right heart catheterization (RHC) is crucial for accurate diagnosis and has significant prognostic and therapeutic implications for patients. In this week's journal, Kim et al. propose a less invasive approach by suggesting the utilization of 4D flow MRI (4D MRI) as a diagnostic tool to differentiate between pulmonary arterial hypertension (PAH) and pulmonary hypertension-heart failure preserved ejection fraction (PH-HFpEF) [1].
