Abstract:
Persistent intercoronary and intracoronary communications were observed on cineangiograms in four patients having vasospastic angina without significant coronary narrowings. On provocation of coronary spasm using ergonovine maleate, these communications seemed to protect myocardium from ischemia, at least partially.
