Right ventricular myocardial deoxygenation in patients with pulmonary artery hypertension

PICO estructurado

Población

Patients with pulmonary artery hypertension (PAH), including a subgroup with systemic sclerosis associated PAH

Intervención

Oxygenation-sensitive cardiovascular magnetic resonance (OS-CMR) and native T1 mapping

Resultado

OS-CMR signal intensity (SI) and native T1 in inferior RV segmentssurrogate

OS-CMR and native T1 mapping can identify in-vivo microvascular right ventricular dysfunction in patients with pulmonary artery hypertension.

Resumen

Blunted OS-CMR SI suggests the presence of in-vivo microvascular RV dysfunction in PAH patients. The native T1 in the inferior RV segments is significantly increased in the PAH patients, particularly among the systemic sclerosis associated PAH group.
