Echocardiographic and CMR measures

PR on Echocardiogram* Regurgitant Fraction on CMR†
≤Mild Moderate Severe Total

PR: pulmonary regurgitation

†

Degree of pulmonary regurgitation: mild if regurgitant fraction <20%; moderate if 20–40%; severe if >40%.

‡

Of the 143 subjects, 135 had measurable PR by CMR, and of the 135, 6 had regurgitant fraction= 0%, therefore total n= 129.
