Multiplane color Doppler TEE. The diagnosis of PFO was advanced with multiplane TEE demonstration of a turbulent, continuous left-to-right shunt (A) within a double contour of the atrial septum (B). LA, left atrium; RA, right atrium.

Before catheterization, however, multiplane color Doppler TEE revealed a turbulent, continuous left-to-right shunt within a double contour image of the atrial septum (Figure 1), that is the hallmark of PFO.

SB inflation, rose up to 5 and 18 mmHg, respectively (Figure 4). Such a worsening of LV diastolic function due to the PFO occlusion suggested us not to perform the definitive procedure with the Amplatzer occluder.
