Abstract
Catheterโinduced spasm has generally been considered to represent an iatrogenic phenomenon without important clinical significance. This report describes two patients who developed catheterโinduced spasm in the proximal segment of the right coronary artery in separate studies performed in different laboratories by means of different catheter techniques. One of these patients developed right coronary spasm on three occasions and, in addition, developed catheterโinduced spasm of the left main trunk during two different studies. These observations would add support to the hypothesis that a predisposition to coronary artery spasm may exist in certain individuals. Catheterโinduced spasm deserves attention, since it may provide a means of identifying spasmโprone individuals.

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
