Direct and continuous observation of subendocardial (deep myocardial) microcirculation provides essential information on coronary circulation, since cardiac contraction affects subendocardial vessels most vigorously. To achieve this aim, we developed a portable needle-probe video-microscope with a charge-coupled-device (CCD) camera to visualize the subendocardial microcirculation. Images of the subendocardial microcirculation of a porcine beating heart were successfully observed in all cases. The vascular compression by cardiac contraction decreased the diameter of subendocardial arterioles and venules by about 20%.
