Coronary Arterial Spasm

Editorial: Coronary artery spasm

“…The author(s) [8] of the present case report remind(s) us that another area of the same vessel, further down distally, may also be involved. This possibility was mentioned in our original paper [9] indeed, in two of these seven patients, spasm did occur in the distal third of the dominant right coronary artery. A similar observation was made by Chahine et al [lo] in two of their eight patients.…”

Left ventriculography induced coronary artery spasm

“…Coronary spasm has also been reported to occur during manipulation of catheters in peripheral veins (Dagenais et al, 1970), arteries (Demany et al, 1968), the left atrium, aorta (Hager and Orth, 1964), and right ventricle (Wennevold et al, 1965). We report a case in which left ventriculography apparently provoked spasm of the right coronary artery.…”

Catheter‐induced spasm during spontaneous attack of variant angina

“…Many speculate whether patients with variant angina are more susceptible to mechanical induction of spasm or whether mechanical induction of spasm is found in patients more likely to have spontaneous spasm. Seveml reports have suggested that patients with catheter-induced coronary spasm are more likely to have spontaneous spasm (Bertrand and Chahine, 1983;Chahine et al, 1975;Demany et al, 1968;Mounter et al, 1983;O'Reilly et al, 1970). Bertrand and Chahine (1983) suggested that catheter-induced spasm may constitute an index of proneness to clinically significant vasospasm.…”

“…Several reports have suggested that patients with catheter-induced spasm are more likely to have spontaneous spasm (Ber-trand and Chahine, 1983;Chahine et al, 1975;Demany et al, 1968;Mountner et al, 1983;O'Reilly et al, 1970), but there is no solid evidence to confirm or refute this suggestion.…”
