Abstract
A patient developed a lesion in the proximal and mid right coronary artery during cardiac catheterization. Following the administration of nitroglycerin, repeat right coronary angiography showed a normal right coronary artery. Therefore, distal lesions associated with catheterβinduced spasm in the same coronary artery should not always be considered βfixedβ lesions; but rather, they may be due to spasm.

Two cases of prolonged catheter-induced right coronary artery spasm, mimicking fixed stenoses, are presented. In one case, the spasm appeared at the same place in sequential catheterizations. This angiographic finding may be easily misinterpreted as a fixed lesion, leading to unnecessary attempts at
