As antegrade options are limited, intervention upon the ostial right coronary artery (RCA) chronic total occlusion (CTO) warrants a retrograde approach. Landmarks for an aggressive approach are concerning as passage of stiff guidewires or electrocautery near the RCA ostium may result in wire passage into structures other than the aorta. We report the first use of transesophageal echocardiography (TEE) to assist retrograde passage of a guidewire into the aorta. For the ostial RCA CTO, TEE guidance may be considered to assist retrograde passage of aggressive guidewires into the aorta.
