Comparison of Cine Magnetic Resonance Imaging with Doppler Echocardiography for the Quantative Evaluation of Tricuspid Regurgitation in Newborn

Abstract

BACKGROUND
Cine MR imaging has been found to bo a non-invasive technique in evaluation cardiac anatomy and cardiovascular function in a variety of cardiac diseases. The capability of this technique for quantatively estimating the severity of regurgitation has not been tested in newborns. The purpose of this study is to compare the degees of tricuspid regurgitation by echorcardiography with those by cine MRI, and verify the utility of MRi in evaluating tricuspid regurgitation.
METHODS
Fifty-one newborns with tricuspid regurgitation were evaluated on the same day by echocardiography and cine MRI. Area and regurgitant fraction of area were estimated at four chamber view by two techniques.
RESULTS
The area of tricuspid regurgitation was similar by two techniques. The correlation for the area(r=0.66, p<0.025) and the regurgitant area fraction(r=0.647, p<0.025) of tricuspid regurgitation obained by cine MRI with echocardiographic data was good.
CONCLUSION
Cine MR imaging can provide quantative data estimating for evaluation of tricuspid regurgitation in newborns.
