The authors present a clinical case of coronary artery spasm in a 62-year-old woman undergoing elective aortic valve replacement surgery for aortic regurgitation. On admission at ICU, the patient developed marked hemodynamic and electrical instability. Emergent coronary angiography demonstrated a pronounced spasm of the distal portion of the right coronary artery, apparently related to compress...

A 60-year-old patient with variant angina was shown to have myocardial ischemia in two different regions supplied by separate major coronary arteries. Neither artery had significant coronary atherosclerotic obstruction. Ventricular fibrillation was noted during ST-segment elevation in anteroseptal leads. The attacks of pain and arrhythmias disappeared during nifedipine therapy.

The total incidence of coronary artery spasm during coronary angiography has been reported to be between 0.26% and 0.93%. The rarity of this phenomenon has been invoked to minimize its clinical significance. Review of a one-year experience in our catheterization laboratory showed that coronary spasm occurred in eight of 274 coronary angiograms (2.93%). In three instances, spasm could not be asc...

The spontaneous occurrence of diffuse three vessel coronary artery spasm was documented during routine coronary angiography in three patients with a history of variant angina. Quantitative angiographic analysis of 18 arterial segments demonstrated that the mean luminal diameter of 1.47 mm during spasm increased to 2.47 mm after the administration of nitroglycerin (p less than 0.0001). The under...

BACKGROUND Myocardial bridge refers to the myocardial tissue with which the coronary artery is partly covered. Though it has long been regarded to be benign, patients with myocardial bridges may present with myocardial ischemia, acute coronary syndromes, coronary spasm, sudden cardiac arrest or even sudden death. CASE PRESENTATION In present study, we reviewed four cases with myocardial bridg...

Background: Brachial artery spasms may occur during transradial cardiac catheterization. The purpose of this study was to examine the relationship between brachial artery spasms after transradial cardiac catheterization and coronary artery disease. Methods: Two hundred and forty-one patients who received transradial cardiac catheterization for diagnosis of coronary artery disease were enrolled ...

Case presentation: A 37-year-old man was admitted in the early morning hours to the emergency department after experiencing excruciating chest pain. The patient was a heavy smoker who gave a history of several previous similar but less intense episodes of pain during the past 2 years; most of them also during the early morning hours. One of his earlier attacks was associated with sensing his he...
