Significant hemodynamic alterations often occur during off-pump coronary artery bypass operations. Historically, left main coronary artery stenosis has been excluded from off-pump coronary artery bypass operations because of this concern. Many articles in recent times support off-pump operations in left main coronary artery (LMCA) stenosis. We describe here a safe ...

Cerebral venous thrombosis (CVT) is a relatively rare cause of stroke and has a wide spectrum of unspecific symptoms, which may delay diagnosis. There are many etiologies, including hematological disorders, trauma, infection, and dehydration. Iron-deficiency anemia (IDA) has been reported as an extremely rare cause of CVT, especially in adults.

Arterial spin labeling can be used to measure both cerebral perfusion and arterial transit time. However, accurate estimation of these parameters requires adequate temporal sampling of the arterial spin labeling difference signal. In whole-brain multislice acquisitions, two factors reduce the accuracy of the parameter estimates: saturation of labeled blood in ...

Congenital mitral ring is a rare type of congenital mitral stenosis. There are two types of mitral ring: the intramitral ring and the supramitral ring. Intramitral rings are often associated with complex valve pathology, and therefore have a worse prognosis than supramitral rings, in which the mitral apparatus is usually ...

Both statins and renin-angiotensin system (RAS) inhibitors inhibit atherosclerotic progression and reduce cardiovascular events. However, it remains unclear whether combination therapy of RAS inhibitor with statin could inhibit plaque progression more than statin alone. Using 64 multislice computed tomography, vessel wall areas (VWAs) and total vascular areas of the left ...
