The use of certain large-caliber (ie, 7F to 9F) coronary guiding catheters for selected neuroendovascular procedures is described in the context of surveying recently developed neurovascular guiding catheters. These large-caliber guiding catheters have proved useful in situations requiring proximal access to tortuous brachiocephalic arteries, permitting coaxial delivery of relatively large neur...

Background Cardiac and vascular anatomy of patients with congenital heart disease (CHD) is often complex and accurate evaluation mandates MR image acquisition in several non-standard planes. This requires significant patient involvement while multiple additional breath-holds are required. For these reasons, the utility of self navigated isotropic 3D-free-breathing whole-heart MRI (SN-3D) was as...

Cardiac computed tomographic angiography (CTA) using multidetector computed tomographic scanners has proven to be a reliable technique to image the coronary vessels. CTA also provides excellent visualization of the mitral and aortic valves, and yields useful information regarding valve anatomy and function. Accordingly, an assessment of the valves should be performed whenever possible during CT...

Blood flow is distributed through the heart muscle via a system of vessels forming the coronary circulation. The perfusion of the myocardium can be hampered by atherosclerosis creating localized obstructions in the epicardial vessels or by microvascular disease. In early stages of the disease, these impediments to blood flow are offset by dilation of the resistance vessels, which normally compe...

An understanding of cardiac health and disease requires knowledge of the various factors that control coronary capillary blood flow. An analysis of coronary capillary blood flow based on a complete set of actual data on the capillary anatomy and elasticity does not exist. Previously, a complete set of data on the branching pattern and the vascular geometry of the pig coronary capillary network ...

the left ventricular aneurysm is one of the most significant complications of myocardial infarction and is defined as the expansion of the ventricular wall. the coronary artery aneurysm is characterized by an abnormal dilation of the localized portion of the coronary artery, and its main cause is atherosclerosis. we herein report an unusual case of coronary artery and left ventricular aneurysms...

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 ...

kawasaki disease is believed to be the commonest vasculitis of medium vessels in asian children. however, the majority of children with kawasaki disease continue to remain undiagnosed perhaps because of the lack of awareness amongst pediatricians. the clinical features of kawasaki disease can be confused with other common conditions such as scarlet fever, stevens johnson syndrome, measles fever...
