The increasing complexity of assessing aortic stenosis (AS) will perhaps haunt cardiologists in years to come. Did we over-complicate it, were we overly ambitious in trying to identify those who might benefit from intervention? These are questions that we will be held accountable for by the vast numbers of patients who now carry some form of this diagnosis, and we have reason to be concerned. T...

Pulmonary stenosis has alw"ays attracted more attention than other forms of congenital heart disease. This was true even in the eighteenth and nineteenth centuries, when the approach to the whole subject was mainly aitatomical, and for that reason academic. In recent years the surgical treatment of pulmonary stenosis has inevitably aroused further interest and has underlined the need for more d...

It has been suggested that the maximal amplitude of the pulmonary valve motion following atrial contraction (Amax) may be useful in the clinical evaluation of patients with valvular pulmonary stenosis. To evaluate the specificity and sensitivity of this measurement in children, we reviewed the echocardiograms of the pulmonary valve of 120 subjects: 57 normal individuals, 25 patients with secund...

THE PURPOSE OF THIS REVIEW IS to discuss the phenomenon of stenosis in extracranial cerebral arteries, its effects on normal blood flow patterns and the biological and clinical implications for the extracranial cerebral circulation. Stenosis, generally defined as a narrowing or constriction, is of particular interest because of its potential to decrease blood flow. Stenosis of the extracranial ...

Twenty-five patients with pure mitral stenosis and nine normal subjects were studied by selective left ventricular cineangiocardiography. Left ventricular volumes were measured at end systole, throughout diastole, and at end diastole. Although filling curves showed that the left ventricles filled slowly in patients with mitral stenosis, normal end-diastolic volumes were attained provided diasto...

PURPOSE To assess spatiotemporal patterns of local perfusion in MR brain perfusion images for patients with unilateral carotid stenosis. MATERIALS AND METHODS MR perfusion images acquired from 12 patients with unilateral carotid stenosis were retrospectively segmented using independent component analysis. Regions of interest selected from the segmentation results were used to measure the time...

Abdominal aortic coarctation is an extremely rare vascular pathology. Its etiology can be congenital or acquired. Here we present a case of acquired infrarenal abdominal coarctation in a 66-year-old woman who complained of low back and legs pain. She had no signs of resting lower limb ischemia, with diminished distal pulses and normal blood pressure in upper and lower extremities. Magnetic reso...

OBJECTIVES To examine long axis excursion in patients with all grades of aortic stenosis and preserved transverse systolic function, and to compare long axis excursion in symptomatic with that in asymptomatic severe aortic stenosis. DESIGN Prospective comparative study. SETTING Regional cardiothoracic centre. PATIENTS 78 patients with all grades of aortic stenosis and normal fractional sh...

OBJECTIVES RNF213 p.R4810K was identified as a susceptibility variant for moyamoya disease in Asia and non-moyamoya intracranial artery stenosis/occlusion disease in Japan and Korea recently. The occurrence of this variant was evaluated in patients with non-moyamoya intracranial artery stenosis/occlusion disease in China. METHODS Two study populations were used in this study. One was recruite...
