Anesthetic management of a pregnant patient with Eisenmenger’s syndrome: A case report

Figure 1 Preoperative echocardiography. A: Image showing the occlusion (manifesting as a stronger echo) between the descending aorta and pulmonary artery (orange arrow); B: Color Doppler echocardiography revealed a bidirectional shunt signal on both sides of the occlusion (orange arrow); C: Spectral Doppler echocardiography revealed the pressure gradient and blood velocity of the bidirectional shunt (orange arrow). Vel: Velocity; PG: Pressure gradient.

Figure 2 Follow-up echocardiography one month after hospital discharge. A: Color Doppler echocardiography revealed only a minor bidirectional shunt signal on both sides of the occlusion (orange arrow); B: Spectral Doppler echocardiography revealed a residual bidirectional shunt, which mainly was from left to right (orange arrow).
