Assessment of the anatomic regurgitant orifice in aortic regurgitation: a clinical magnetic resonance imaging study

Abstract

Visualisation and planimetry of the ARO in patients with AR are feasible by MRI. There is a strong correlation of ARO with RgV and RgF assessed by PVM and with invasively graded AR at catheterisation. Therefore, determination of ARO by MRI is a new non-invasive measure for assessing the severity of AR.
