We describe a patient with a focal abdominal aortic stenosis without renovascular stenosis manifested as severe hypertension. Although hypertension and unilateral or bilateral renal artery stenosis are common in abdominal aortic stenosis, patients presenting with hypertension as the sole clinical feature without renal artery stenosis are rare. A 12-year-old boy was admitted to our department fo...

OBJECTIVES To investigate the contribution of plaque size and vessel remodelling to coronary artery stenosis and to assess the role of vessel shrinkage (negative remodelling) across a wide range of lesions. DESIGN Postmortem study of coronary remodelling in perfusion fixed hearts. SUBJECTS 24 men and 24 women who died suddenly with coronary artery disease. MAIN OUTCOME MEASURES Percentage...

Stenosis of spinal canal becomes important only when it resul...

OBJECTIVES To compare magnetic resonance myocardial perfusion imaging (MRI) with anatomical assessment by multislice computed tomography (MSCT) coronary angiography and conventional coronary angiography. DESIGN AND PATIENTS In this prospective study, 53 patients (60% male, average age 57+/-9 years, 83% intermediate pre-test likelihood) underwent 1.5 T MRI, 64-slice MSCT and conventional coron...

A Valsalva-like maneuver was performed during cardiac catheterization by a normal group of individuals and a group of patients with acoustic evidence of mitral stenosis. The latter group was subdivided according to its response to the maneuver. The mild group, like the normal group, showed an "overshoot" of blood pressure and a bradyeardia in the post-straining period, whereas the severe mitral...

Plasma renin activity and one-dimensional echocardiographic measurements of the left atrium and left ventricle as well as function indices were studied repeatedly in 20 children with various cardiopathies (ages: 9 months to 15 years) before and after corrective surgery. Nine children had tetralogy of Fallot, four had pulmonary stenosis, four had rheumatic heart disease, two had ventricular sept...

The accuracy of exercise electrocardiography in detecting a physiologically significant coronary artery stenosis has been assessed previously by comparing the exercise test with a coronary arteriogram. The inherent inaccuracy of visually determined percent diameter stenosis measurements might have lead to the conclusion that the exercise electrocardiogram was less accurate than it truly was. To...
