Patients with Dextro-transposition of the great arteries status post atrial switch (dTGA s/p atrial switch) are “at-risk” for systemic right ventricular (RV) dysfunction. Due to complex RV geometry, echocardiography (Echo) does not allow accurate determination of ejection fraction (EF), but cardiac magnetic resonance imaging (CMR) allows quantitative right ventricular assessment. Measures of ventricular deformation may be precursors to global ventricular dysfunction. The primary aim of this study was to characterize imaging and clinical findings for adult patients with dTGA s/p atrial switch.

心房转换后大动脉 d 转位患者全身右心室超声心动图与心脏磁共振成像评估

心房转换后大动脉右转转位（dTGA s/p 心房转换）的患者存在全身性右心室 (RV) 功能障碍的“风险”。由于复杂的 RV 几何结构，超声心动图 (Echo) 不能准确确定射血分数 (EF)，但心脏磁共振成像 (CMR) 允许定量右心室评估。心室变形的测量可能是整体心室功能障碍的前兆。本研究的主要目的是描述成人 dTGA s/p 心房转换患者的影像学和临床发现。
