Why the study?
The application of a new 10 French intracardiac echocardiography catheter with phased array and Doppler transducer for assessing epicardial and intramyocardial coronary blood flow was explored.
Does a new 10 French intracardiac echocardiography catheter accurately assess epicardial and intramyocardial coronary blood flow compared to a Doppler guide wire in closed chest dogs?
Does a new 10 French intracardiac echocardiography catheter accurately assess epicardial and intramyocardial coronary blood flow compared to a Doppler guide wire in closed chest dogs?
A new 10 French ICE catheter with Doppler capabilities accurately measures coronary blood flow and flow reserve compared to a Doppler guide wire in a preclinical model.

Barold et al. (2002) studied this question. 10 French intracardiac echocardiography (ICE) catheter vs. Doppler guide wire was evaluated on Coronary flow reserve correlation with Doppler guide wire (r = 0.90, p=< 0.0001).
