Figure 1From: 1109 Quantification of the orifice area of bioprostheses in aortic position by cardiovascular magnetic resonanceWe compared magnetic resonance planimetry with echocardiographic continuity equation to assess the orifice area of aortic bioprostheses. Orifice areas correlated well between both methods. Thus, CMR planimetry may offer an alternative non-invasive method to quantify the orifice area of bioprostheses.Back to article page
