Comparison between Cardiac CTA and Echocardiography for Assessment of Ventricular Septal Rupture Diameter and Its Effect on Transcatheter Closure

Figure 3

(a) Preoperative horizontal plane imaging by cardiac CTA. (b) preoperative coronal plane imaging by cardiac CTA, showing that the right ventricular surface defect has the moderator band barrier. (c) Postoperative horizontal plane imaging by cardiac CTA. (d) Postoperative coronal plane imaging by cardiac CTA, showing that the occluder waist diameter is severely compressed due to the moderator band barrier. The red arrow in the figure indicates the VSR position, the blue arrow indicates the adjustment band, and the green arrow indicates the occluder.
