BACKGROUND ACCF/SCCT/ACR/AHA/ASE/ASNC/NASCI/SCAI/SCMR 2010 Appropriate Use Criteria for Cardiac Computed Tomography (AUC2010) does not incorporate prior coronary computed tomographic angiography (CCTA) results in the appropriateness of a CCTA examination. The purpose of this study was to explore the criteria for forgoing repeat CCTA among patients with clinical scenarios suggesting CCTA as appr...

To determine the effect of atherosclerotic coronary lesions on myocardial blood flow in patients at rest, regional myocardial blood flow was measured distal to stenotic lesions in 29 patients with isolated proximal lesions of the left anterior descending artery. Severity of coronary stenosis was measured by computer-assisted cinevideodensitometric analysis of digitized coronary arteriograms. Re...

Knowledge of the structural changes in the commissures, cusps, and chordae tendineate is important to the understanding of the pathologic physiology of mitral stenosis and its surgical correction. Study of 70 hearts with mitral stenosis disclosed that a frequent cause of the obstruction was commissural fusion or shortening of the chordae tendineae or both. In a small percentage of hearts, mitra...

From 1981 to 1985 a prospective study on normal pressure hydrocephalus was performed. One of the aims of this study was to determine the site of CSF obstruction. Among 17 consecutive patients with a tentative diagnosis of normal pressure hydrocephalus, nine appeared to have non-communicating hydrocephalus most probably due to primary non-tumoural aqueduct stenosis. This unexpected finding provi...

The association of angina pectoris with mitral stenosis has interested cardiologists for many years. The first reference seems to be that of Nothnagel (1891) who found anginal pain in 18 per cent of his patients with mitral stenosis. There have been many case reports since that time of angina pectoris occurring in young subjects with mitral stenosis a number of instances normal coronary arterie...

In ten normal subjects, we observed an initial hump in the aortic root echocardiogram after the onset of the QRS complex, following which a sharp anterior motion was noted. The onset of the anterior motion of the aortic root coincided with the onset of the upstroke of the aortic root pressure pulse and the onset of the velocity signal in five of seven patients with coronary arterial disease; in...

PURPOSE Normal myocardial perfusion imaging (MPI) is associated with excellent prognosis. However, in patients with persisting symptoms, it may be difficult to determine the patients in whom invasive angiography is justified to rule out false negative MPI. We evaluated predictors for severe stenosis at invasive angiography in patients with persisting symptoms after normal MPI. METHODS 229 con...

We report a case of 56-year-old woman who presented with clinical features suggestive acute pancreatitis. She had similar episode 5 years ago. A blood pressure (BP) recording 80/50 mmHg in the presence pancreatitis led to diagnosis circulatory shock and vasopressors were about be commenced. However, her overall appearance was stable measurement BP lower limbs normal. An angiogram revealed left ...

INTRODUCTION AND OBJECTIVES The prognosis of patients with severe aortic stenosis, low aortic gradient and preserved ejection fraction is controversial. Our study analyzed the prognosis of these patients and its relation to pressure gradient and aortic valve flow. METHODS We performed a retrospective cohort study of 363 consecutive patients with severe aortic stenosis and preserved ejection f...
