Figure 39.2 Pulse wave Doppler recording shows the velocity of coronary sinus entrance flow was almost 1.2 m/sec.
Doppler recordings of left and right ventricular outflow tract; Qp/Qs = 1.9 indicated there was a left to right shunt (Figure 39.3).
Figure 39.3 Doppler recordings of left and right ventricular outflow tract; Qp/Qs = 1.9 indicates there is a left to right shunt.
Figure 39.4 illustrates (a) diagram of unroofed coronary sinus defect (UCSD). (b) Three-dimensional (3D) apical short-axis view (crop from basal) shows the relation among the coronary sinus, defect of sinus (white arrow) and left atrium (LA). The RV and atrial cavity size was mildly enlarged.
