Figure 4From: The role of cardiovascular magnetic resonance in stratifying paravalvular leak severity after transcatheter aortic valve replacement: an observational outcome studyComparison of mean paravalvular leak (PVL) grade by qualitative echocardiography (QE), semi-quantitative echocardiography (SQE), and cardiovascular magnetic resonance (CMR). PVL classification: mild = 1, moderate = 2, severe = 3. Error bars = 2 standard errors of the mean. P values are for paired-samples t-test.Back to article page
