RIGHT VENTRICULAR CONTRACTILE RESERVE CHARACTERIZED BY TREADMILL EXERCISE CARDIAC MAGNETIC RESONANCE IMAGING IN PULMONARY ARTERIAL HYPERTENSION

Cardiac magnetic resonance (CMR) imaging in pulmonary arterial hypertension (PAH) may aid in assessment of right ventricular (RV) morphology and function as well as contractile reserve (RVCR). Previous data suggests that RVCR may be diminished in patients with PAH patients by bicycle ergometer (eCMR
