Multivessel or multisegment spasm in patients with known widespread coronary atherosclerotic disease is an infrequent occurrence. We describe a prolonged spasm of both the left main and the left anterior descending artery in a patient with chronic effort angina and multivessel coronary artery disease, who previously underwent percutaneous coronary intervention and drug eluting stents implantati...

Coronary artery spasm is an uncommon, but well recognized, etiology for acute myocardial infarction. However, cardiogenic shock with myocardial infarction resulting from simultaneous multiple coronary artery spasm has been rarely reported, and not in Korea. Recently, we experienced such a case in a 50-year-old Korean man without previous diagnosis of variant angina. The patient, hospitalized fo...

A 64-year-old man was admitted to hospital under the suspicion of unstable angina pectoris. Coronary angiography showed that he has a single coronary artery originating from the right coronary artery (RCA) without significant fixed stenosis. Acetylcholine was superselectively infused into the left main coronary artery (LMCA), and confirmed the coronary vasospastic occlusion associated with ches...

Coronary artery spasm has been recognised recently as a possible cause of perioperative myocardial ischaemia after coronary artery bypass grafting. We report on one case and review the published reports. We emphasise the clinical picture of the patient who is liable to have spasm and the necessity for a prompt diagnosis and correct treatment.

Coronary artery spasm is a recognized cause of myocardial infarction. This report describes a case of myocardial infarction attributed to pure coronary spasm which was halted by a double perfusion with streptokinase and nitroglycerin. Further coronary artery spasm leading to a myocardial infarction could not be avoided several weeks later, although the patient was left on calcium channel blocke...

As pharmacological spasm provocation tests, acetylcholine (ACh) [1-3] and ergonovine (ER) [4,5] are employed in the cardiac catheterization laboratory. However, we often encounter the major and minor complications during performing these procedures. As a diagnostic tool, we should perform spasm provocation tests more safely without major complications. Multiple and proximal spasm documented by ...

Intercoronary arterial connection between normal coronary arteries is a rare variant of coronary anatomy in which there is open-ended circulation. It is distinguished from collaterals seen in the occlusive coronary artery disease. We report a case of bidirectional intercoronary communication between the left circumflex artery and the right coronary artery without occlusive coronary artery disea...

Coronary artery vasospasm can cause a transient, abrupt, marked decrease in the diameter of an epicardial coronary artery. Various mechanisms have been reported, including vasoconstrictor substances, pharmacologic stimuli, and neurohumoral effects. Spasm usually develops at the site of subcritical or critical stenosis, but it may also occur in angiographically normal arteries, particularly in A...

Catheter-induced spasm of the left main coronary artery is rare during catheterization. We present several cases in which the occurrence of both ostial left main and right coronary spasm suggests that multiple sites of spasm may be a clue to this important diagnosis.
