Intraoperative delineation of the coronary anatomy during coronary bypass operations is critical for successful revascularization. Two techniques utilizing fluorescein to enhance the visualization of the coronary arteries were evaluated in a canine model. A previously described method using fluorescent cardioplegia to arrest the heart produced sub-optimal contrast. Excellent visualization of the coronary circulation was obtained when the heart was arrested with crystalline cardioplegia and then reinjected with fluorescein cardioplegia.
