Left main dissection is usually caused by catheter manipulation during diagnostic angiography and occasionally during angioplasty. It is a dangerous complication due to the potential risk of left main territory ischemia. We report a novel iatrogenic cause of left main dissection from a retrograde wire during ostial left anterior descending ...

Aneurysms of the left main coronary artery (LMCAA) are extremely uncommon, with an incidence of 0.1%. The main etiologic factor is atherosclerosis. Other causes include connective tissue disorders, trauma, vasculitis, congenital, mycotic, and idiopathic. These dilated sections of coronary artery are not benign pathology because they are subject to spasm, ...

Retrograde wire approach has been emerged as a useful tool to enhance success rate in coronary chronic total occlusion (CTO) intervention. Therefore, we tried to report the initial experience of retrograde approach and its clinical implication on CTO intervention. From February 2007 to July 2008, retrograde approaches were performed in ...

Intravascular ultrasound (IVUS) has enabled the measurement of minimal luminal area of coronary stenoses. We evaluated the hypothesis that angiographic three-dimensional reconstruction of luminal dimensions may be able to provide similar measurements to IVUS in intermediate coronary lesions. We retrospectively enrolled patients undergoing invasive coronary angiography and IVUS for the ...

OBJECTIVE: Earlier studies have often required the absence of obstructive coronary artery disease (CAD) as the criteria. However, it is probable that patients with tako-tsubo cardiomyopathy have an incidental CAD because most patients are elderly. We assessed the prevalence of incidental CAD. METHODS: We reviewed coronary angiograms of 97 Japanese ...

A 74-year-old male underwent cardiac catheterization that revealed a chronic total occlusion of the proximal left anterior descending coronary artery (LAD). The right coronary artery provided only faint collateral circulation to the LAD. Multislice computed tomography (MDCT) disclosed that a conus artery took off directly from the aorta and provided ...

AIMS: Defining vessel diameters and angles that comprise coronary side-branch intersections could assist in tailoring treatments to match anatomy, improve haemodynamic flow, and minimise mechanical trauma. We sought to characterise intersections of main vessels and side-branches by measuring actual diameters, angles, and shapes at the ostia in human coronary arteries. ...

INTRODUCTION: Male genital dysfunction was recognized as a complication following anterior approach lumbar surgery. Disruption of efferent sympathetic pathways such as the abdominal aortic plexus (AAP) and superior hypogastric plexus (SHP) which lied pre-abdominal aorta and iliac artery had been thought as the main reason. Though there were some clinical ...

Dobutamine stress echocardiography is a sensitive tool used for the detection of ischaemia. However, on occasion, there is a discrepancy between angiographic lesion severity and what would be expected from the abnormalities seen at stress echo. When stress echo underestimates severity it may be the case that collateral vessels play ...

Coronary aneurysms represent anomalies identified in 0.15-4.9% of patients undergoing coronary angiography. At present there is no uniform definition of this pathology. According to current definitions, the term "aneurysm" refers to both diffuse over 150% dilation of the largest diameter of a coronary artery, and limited spherical or saccular dilation. ...
