we report a rare case of acute right coronary artery stenosis developing in a patient undergoing aortic valve replacement. we present a case report with a brief overview of the literature relating to coronary artery occlusion associated with cardiac valve surgery – the theories and treatments are discussed. a 85 year-old female was admitted under the care of the  cardiothoracic team with signs ...

introduction: the aim of this study was to evaluate the impact of measurement of coronary artery calcification score (cac) in patients with suspected coronary artery disease (cad) and a normal myocardial perfusion scan. methods: in a prospective study we measured the calcium score of 74 patients (29 m, 45 f, mean age 58.7 (m) and 64.4 (f)) with suspicion of cad and a normal perfusion scan. in ...

cardiovascular disease remains the principal cause of death in the modernized world.   several novel noninvasive imaging techniques have been recently developed to improve diagnosis of cardiac and coronary disease.   of these advances, multidetector computed tomographic (mdct) angiography has evolved most dramatically to transform computed tomography from a single-slice trans-axial modality to ...

background: investigators frequently encounter continuous outcomes with plenty of values clumped at zero called semi-continuous outcomes. the gensini score, one of the most widely used scoring systems for expressing coronary angiographic results, is of this type. the aim of this study was to apply two statistical approaches based on the categorization and original scale of the gensini score to ...

origination of the right coronary artery (rca) from the left anterior descending (lad) artery is a case of single coronary artery. it is an extremely rare coronary artery abnormality and usually an incidental finding during coronary angiography. a 73-year-old man with a medical history of hypertension arrived with chest pain. medical therapy started for st elevated myocardial ischemia. during h...

coronary artery disease is one of the most common causes of mortality and morbidity across the world. its treatment includes medical treatment, coronary artery bypass graft (cabg) and percutaneous coronary intervention (pci). the purpose of this study was to investigate the effect of pci on echocardiographic findings of left ventricular (lv) systolic and diastolic function. 115 patients with co...

Percutaneous coronary intervention in the setting of coronary bifurcation lesions is associated with increased risk for complications. The goal of this manuscript is to review the currently available classifications for coronary artery bifurcation lesions with a guide to the use of specific coronary bifurcation techniques based on lesion characteristics

The acute occlusion of a coronary artery without the evidence of myocardial infarction might immediately affect both the diagnosis and treatment of coronary artery disease. We present the case with a sudden occlusion of the left main coronary artery without typical chest pain following an exercise tolerance test and rapid spontaneous reperfusion of the left main coronary artery.

coronary artery perforation is a rare, but potentially serious, complication of percutaneous coronary intervention and is associated with a high incidence of death, q-wave myocardial infarction, and emergency coronary bypass surgery. management is different but requires prompt recognition and treatment. we describe a case of coronary perforation only after guidewire removal and also review the ...

coronary heart disease has been one of the main threats of human health. coronary angiography is taken as the “gold standard” for the assessment of coronary artery disease. but sometimes, the images are difficult to interpret visually because of the crossing and overlapping of the vessels in the angiograms. vessel extraction from x-ray angiograms has been a challenging problem for several years...
