An experimental model for heart-mural coronary artery-myocardial bridge was established based on the theory of haemodynamics. The application of the model demonstrated that it can repeat to great extent the phenomenon of the myocardial bridge compressing the mural coronary artery, which results in abnormal haemodynamic characteristics. The results of simulation ...

OBJECTIVE: The purpose of the present study was to describe our experience with myocardial infarction with normal coronary arteries (MINCA) with regards to the prevalence, clinical characteristics, possible underlying etiologies (including Takotsubo cardiomyopathy, TCM) and the short- and long-term outcomes associated with this condition. METHODS: We retrospectively analyzed the records ...

Spontaneous coronary artery dissection (SCAD) is a rare cause of acute coronary syndrome and sudden cardiac death. It should be suspected in every healthy young woman without cardiac risk factors, especially during the peripartum or postpartum periods. It is important to check for a history of drug abuse, collagen vascular ...

A 62-year-old lady was admitted with clinical and electrocardiograph features of acute myocardial infarction. Urgent coronary arteriography was performed, demonstrating a single discrete stenosis of one coronary artery. Following intracoronary injection of GTN, this stenosis completely resolved, as the symptoms did. The causes of acute myocardial infarction with normal coronary ...

Myocardial bridge is a congenital anomaly characterized by narrowing of some of the epicardial coronary arterial segments running in the myocardium during systole. Occasionally, the compression of a coronary artery by a myocardial bridge can be associated with the clinical manifestations of myocardial ischemia, and might even trigger a myocardial ...

Variant angina is caused by focal spasm of the epicardial coronary arteries and is variably associated with atherosclerotic coronary disease. We present the clinical course of profound coronary spasm in a woman which resulted in life-threatening symptoms. Although not previously reported, administration of the endothelin antagonist bosentan resulted in complete ...

Coronary artery dissection is a rare but well-described cause for myocardial infarction during the post-partum period. Dissection of multiple coronary arteries is even less frequent. Here we present a case of recurrent post-partum coronary artery dissections. This unusual presentation poses unique problems for management. A 35 year-old female, gravida 3 ...

During the last century, many investigators reported on myocardial bridges in the adult human heart. In the present study, 39 human fetal hearts (the mean gestastional age was 30 weeks) were studied for myocardial bridging, and the results were correlated with adult data. Among the 39 (27 male and 12 ...

Myocardial infarction in the absence of significant atherosclerotic coronary artery disease is not uncommonly encountered in clinical practice. This has been more often seen with the current sensitive biomarker assays for myocardial necrosis. Acute illnesses, spontaneous coronary dissection, sepsis, pulmonary embolism and coagulation disorders are some of the common clinical ...

Coronary artery spasm plays an important role in the pathogenesis of many types of ischemic heart disease, not only in vasospastic angina but also in myocardial infarction and sudden death, particularly in the asian population. Patients with vasospastic angina are known to have defective endothelial function due to reduced nitric ...

Transient left ventricular dysfunction syndrome (TVLDS) has been rarely observed during anaphylactic shock and its pathophysiology remains still enigmatic. Multivessel epiicardial coronary spasm or coronary microvascular impairment were suggested as primary causative mechanism. Alternatively, the release of various inflammatory mediators including histamine could induce a coronary artery spasm or erosion/rupture ...

Rho-kinase (ROCK) is one of the effectors of the small GTP-binding protein Rho. Accumulating evidence suggests that the Rho/ROCK system may play an important role in the pathogenesis of atherosclerosis and coronary vasospasm via its action in vascular smooth muscle cell contraction, endothelial function and the inflammatory process. Recent observations ...

Coronary artery spasm (CAS) is a dangerous complication during cardiac surgery, causing arduous weaning of extracorporeal circulation (ECC) and myocardial tissue loss with consequent left and right ventricular dysfunctions. We describe the case of a 67-year-old man with hypertension and smoking habit, with ECG evidence of lateral myocardial ischemia without ...

BACKGROUND/PURPOSE: Myocardial bridging (MB) is a condition in which a segment of the major epicardial coronary artery is tunneled within and surrounded by the myocardium. This condition has been linked to severe complications. The aim of this study was to evaluate the incidence of MB in Taiwanese subjects examined with ...

The myocardial tissue covering the artery is termed a myocardial bridge. But so far many researches on the myocardial bridge have been involved with clinical patients or animals, which have some limitations (e.g. lack of systematicness, difficulties in measuring the flow in the mural coronary artery and so on). Designing ...

Myocardial bridging is a congenital anomaly in which a segment of a coronary artery runs intramuscularly. Although traditionally considered as a benign condition, myocardial bridging may be associated with clinically important complications such as myocardial ischemia, acute coronary syndromes and sudden death. We report the case of a highly symptomatic ...

Significant and serious cardiovascular end-points can be seen in patients with myocardial bridging although it has been thought as a benign condition. Unfortunately, there is no consensus on 'which diagnostic tool has prognostic significance?'. Conventional transthoracic echocardiography can be used for this purpose as in the presented case.

A 65-year-old man with advanced renal cell carcinoma was admitted due to continuing chest pain at rest. Two weeks before his admission, sorafenib had been started. He was diagnosed with non-ST-elevation myocardial infarction by laboratory data and electrocardiogram. Enhanced heart magnetic resonance imaging also showed subendocardial infarction. However, there was ...

Myocardial bridging constitutes a congenital, usually benign, coronary abnormality defined as a segment of a major epicardial coronary artery that follows an intramural course through the myocardium. On the basis of clinical and histopathological data, myocardial bridges appear to be spared from atherosclerosis. Although the mechanisms involved are largely unknown, ...

Congenital coronary artery anomalies are rare, with an incidence of about 0.06-1.3 percent of all patients undergoing cardiac catheterisation. They are commonly asymptomatic, but potentially serious lesions may lead to myocardial ischaemia, infarction and/or sudden cardiac death. The occurrence of a concomitant stenotic lesion is exceedingly rare. We report an ...

5-aminosalicylic acid (mesalamine) rarely induces hypersensitivity reactions. If chest pain associated with atypical electrocardiographic changes are seen during its administration, one should always bear in mind type I variant of Kounis syndrome. This variant includes patients, of any age, with normal coronary arteries, without predisposing factors for coronary artery disease, ...
Sloan Kirk - - 2008
A 50-year-old man without previous coronary disease presented with an inferior myocardial infarction following exercise. He was initially treated with thrombolytic therapy and nitroglycerin. Subsequent coronary angio-graphy and cardiac computed tomography demonstrated an anomalous right coronary artery originating from the left coronary sinus and passing between the aorta and main ...
