Qualitative echocardiographic assessment of aortic valve regurgitation with quantitative cardiac magnetic resonance: a comparative study.

摘要: This study examined the correlation of echocardiography (ECHO) and Cardiac Magnetic Resonance (CMR) in assessment aortic valve regurgitation (AR) children young adults with congenital heart disease. We hypothesized that qualitative ECHO correlates insufficiently quantitative CMR data compared subjective evaluations objective measurement regurgitant fractions (RF) by CMR. Patients who had both assessments AR within 60 days each other were included. The (mild, moderate, severe) left ventricular dimension at end diastole recorded. RF was quantified using phase-contrast velocity mapping. Repeat review grading performed a blinded single reader randomly chosen subgroup patients. In 43 patients studied, statistical significance observed CMR-RF between mild severe grades. There significant overlap Mild corresponded to an (%) 0-29, moderate 1-40, 5-58. Overlap more Results similar group whom interpreted assessment. conclusion, results derived from real-life multiple-reader laboratory showed inconsistencies AR, wide range objectively measured given grade. is less reliable identifying often overestimating severity. Quantitative potentially useful supplement for management decisions medical surgical therapies AR.
