Figure 2: Grade of shunt assessed by TCCD and ICA Doppler ultrasound. Comparison of RLS quantification assessed by TCCD and ICA Doppler ultrasound. Grade 0: 0 MES; Grade 1: 1–10 MES; Grade 2:>10 MES; Grade 3: Curtain effect. MES=Micro-embolic signals, TCCD=Transcranial Doppler Ultrasound, ICA=Internal carotid artery, RLS=Right-left shunt
