Patients with aortic regurgitation can present management challenges, particularly when asymptomatic, and current indications for surgery focus on left ventricular (LV) dilation or reduced function. In some cases this may be too late however, as prognosis is already reduced once significant dilation or dysfunction is present. Quantifying the aortic regurgitation itself has not been used to guide management, due to the difficulty in achieving this with echocardiography. Cardiovascular magnetic resonance (CMR) can accurately quantify both aortic regurgitation and LV volumes/function, though the clinical utility of this has not previously been demonstrated. We therefore examined whether quantifying regurgitation was superior to LV functional indices for identifying patients requiring aortic valve replacement.
Quantifying aortic regurgitation with CMR accurately identified patients requiring surgery and was superior to indices of LV volume or function. Its use in patients with aortic regurgitation should be encouraged.
