Abstract
Methods Healthy controls and patients with heart failure related structural heart disease underwent a standard cardiac magnetic resonance examination. Right and left ventricular ejection fraction (EF) and end diastolic volumes (EDV) were traced from cine imaging. RVD was defined as RVEF less than mean minus 2 standard deviations of healthy gender matched controls. RVE was defined as either indexed RVEDV or RVEDV/LVEDV exceeding mean plus 2 standard deviations of healthy gender matched controls. The prevalence of RV abnormalities and pattern of ventricular remodeling was compared among patient subgroups.
Highlights
Right ventricular dysfunction (RVD) and enlargement (RVE) are increasingly associated with poor outcomes their prevalence among patients with heart failure and those at risk has not been well characterized
RV dysfunction and/or enlargement are prevalent among patients with heart failure related structural heart disease
Routine assessment is recommended in 3-D cardiac imaging
