Key result
CMR-derived LVESVi identifies risk of death or heart failure in asymptomatic chronic AR.
Why the study?
Does CMR quantification of LVESVi and AR severity identify the risk of death or incident heart failure in patients with chronic moderate or severe aortic regurgitation?
Does CMR quantification of LVESVi and AR severity identify the risk of death or incident heart failure in patients with chronic moderate or severe aortic regurgitation?
CMR quantification of LVESVi and AR severity can identify patients at risk of death or incident heart failure among those with chronic moderate or severe aortic regurgitation who have minimal or no symptoms.
CMR LVESVi may aid risk stratification in asymptomatic chronic AR; extends LV remodeling data but requires prospective validation before practice change.
In patients with chronic moderate or severe AR, patients presenting with heart failure symptoms have greater LVESVi by CMR than those with no or minimal symptoms. In patients with no or minimal symptoms, CMR quantification of LVESVi and AR severity may identify those at risk of death or incident heart failure and therefore should be considered in the clinical evaluation and decision-making of these patients.
