北美成人先天性心脏病(CHD)呈增长趋势,对这一群体,放射学在初始评估和监测中起着重要作用。胸部X线片和超声心动图为一线评估手段,必要时需行MRI和CT检查。磁共振成像和CT能提供容积数据资料,用于对心脏解剖学及其功能做更为广泛的评估,能测量血流,以便对左向右分流、射血分数和压力差做定量分析。虽然这种无创性成像具有局限性,但可对大多数病变做评估,而无需做心导管。这种无创性成像对先天性心脏病矫正手术系列评估特别有用,因为这些病人,近半数需做≥2次手术[1]。
Adult North American adult congenital heart disease (CHD) is an increasing trend for this group, radiology in the initial assessment and monitoring plays an important role. Chest X-ray and echocardiography as a first-line assessment means, if necessary, MRI and CT. Magnetic resonance imaging and CT provide volumetric data for a more extensive assessment of cardiac anatomy and its function, and measurement of blood flow for quantitative analysis of left-to-right shunting, ejection fraction, and pressure differentials. Although this noninvasive imaging has limitations, most lesions can be evaluated without the need for cardiac catheterization. This noninvasive imaging is particularly useful for the series of congenital heart disease corrective surgeries, as nearly half of these patients require ≥2 surgeries.
