Figure 1 Effect of cone reconstruction on right ventricle forward flow, measured with cardiac magnetic resonance (CMR) imaging. A, Pre- and postoperative CMR images of Ebstein's anomaly, showing that the cone operation reduces right atrium size and enhances left ventricle size. B, The right ventricle achieves improved forward flow volume into the main pulmonary artery (MPA), as measured by CMR imaging phase-contrast flow mapping. preop, Preoperative; postop, postoperative.

Figure 2 Preoperative (preop) and postoperative (postop) New York Heart Association (NYHA) functional class. Cone reconstruction significantly improves functional class as measured by the NYHA grading system.

Figure 3 Effect of cone reconstruction on objective exercise capacity preoperatively (preop) and postoperatively (postop). The cone reconstruction increased objective exercise capacity in this study, as measured by absolute peak oxygen uptake (VO2 max) and the percentage of predicted VO2 max achieved.
