The cooling effect of coronary blood flow on heart: a new approach.
We tested the hypothesis that blood flow through the coronary arteries may have a cooling effect on heart. The difference (?T) of blood temperature between coronary sinus and right atrium was calculated, during and after acute complete occlusion of blood flow in left coronary artery by balloon dilatation and confirmed by a Doppler guidewire. Coronary sinus blood temperature increased during interruption of coronary blood flow with balloon dilatation.
