Why the study?
Do right ventricular mass, volume, and function predict mortality and treatment failure in patients with idiopathic pulmonary arterial hypertension?
Do right ventricular mass, volume, and function predict mortality and treatment failure in patients with idiopathic pulmonary arterial hypertension?
Large right ventricular volume, low stroke volume, and reduced left ventricular volume provide strong independent prognostic information for mortality and treatment failure in patients with IPAH.
Supports volumetric CMR for IPAH prognosis; hypothesis-generating and should not yet change practice.
The RV contains prognostic information in IPAH. A large RV volume, low SV, and a reduced LV volume are strong independent predictors of mortality and treatment failure.
