    Initial left coronary angiogram (left: left anterior oblique view) shows the collateral vessels from the left anterior descending artery to the right coronary artery (arrows). Right coronary angiogram (right: left anterior oblique view) shows severe stenosis of the proximal right coronary artery (arrow).

    The vasospasm of the right coronary artery was relieved by administration of isosorbide dinitrate to the right coronary artery, and moderate organic stenosis remained (arrow). The collateral vessels to the right coronary artery, which were seen on the initial left coronary angiogram, can no longer be visualized.
