Ascending Aortic Diameters in Congenital Aortic Stenosis: Cardiac Magnetic Resonance versus Transthoracic Echocardiography

摘要: OBJECTIVES/BACKGROUND: Congenital aortic stenosis (AS) is the most common obstructive left heart lesion in young adult population and often complicated by dilatation. Our objective was to evaluate accuracy of imaging with transthoracic echocardiography (TTE) compared cardiac magnetic resonance (CMR). METHODS: Aortic diameters were measured at 4 levels CMR TTE. Agreement concordance assessed Pearson's correlation Bland-Altman analysis. RESULTS: Fifty-nine patients (age 33 +/- 8 years; 66% male) congenital AS a bicuspid valve (BAV) included. generally smaller TTE than CMR. The best found level sinotubular junction (R(2) = 0.78) bias 1.46 mm (limits agreement: -5.47 +8.39 mm). In an aneurysm >40 (n 29) agreement between be less good when normal diameters, especially proximal ascending aorta. both modalities better type 1 BAV 2 BAV. Intra- interobserver variability (1.8-5.9%) (6.9-15.0%). CONCLUSIONS: superior for aorta AS, present. Therefore, ideally should performed least once ensure not missed.
