Intracardiac Echocardiography Guided Transeptal Catheter Injection of Microspheres for Assessment of Cerebral Microcirculation in Experimental Models

Figure 3

Colour Doppler imaging during intracardiac echocardiography. Flow through interatrium septum is seen via Doppler imaging, excluding iatrogenic perforation of atrium wall and confirming correct positioning of transseptal catheter into the LA.
