The relationship of left atrial contraction to ventricular filling was studied in 24 patients. Eight patients had aortic stenosis, eight had mitral stenosis, and eight others served as a control group. All had normal sinus rhythm. Cineangiocardiographic volumetric determinations of the left ventricle were done throughout the cardiac cycle, and the rate of left ventricular filling before and dur...

Central vein stenosis is a well-documented consequence of cardiovascular implantable electronic devices. In hemodialysis patients, where preserving venous real estate is crucial, use of subcutaneous implantable cardioverter-defibrillators (S-ICDs) remains controversial. We present a novel approach for implanting an S-ICD in a patient with endstage renal disease, central venous stenosis, and pre...

A discrete MIBI avid lung lesion was found in cinematic views of myocardial perfusion imaging (MPI) of a 59 year-old woman. Interestingly, the abnormal uptake in the lung was detectable only in the rest phase images and not in the images acquired in the stress phase. MPI was performed for pre-operation cardiac risk assessment before correction surgery for spinal canal stenosis.  She had no...

The cardiac abnormality most frequently found in rubella syndrome is a combination of branch pulmonary artery stenosis and patent ductus arteriosus, though isolated branch pulmonary artery stenosis is twice as common as isolated patent ductus arteriosus [1]. However, a wide variety of cardiac malformations may be produced, such as ventricular and atrial septal defects, stenosis of the pulmonary...

OBJECTIVES We sought to compare the diagnostic information obtained from noninvasive characterization of coronary artery disease by using multidetector computed tomography (MDCT) and myocardial perfusion imaging (MPI) and to compare findings with the use of invasive coronary angiography and intravascular ultrasound (IVUS). BACKGROUND Preliminary comparisons have suggested that abnormal myocar...

The effect of CC-chemokine receptor 7 (CCR7) and CC-chemokine ligand 19 (CCL19) on rheumatic mitral stenosis is unknown. This study aimed to explore the roles of CCR7 and CCL19 in rheumatic mitral stenosis by measuring the expression of CCR7 and CCL19 in human mitral valves from rheumatic mitral stenosis patients. Additionally, we examined their effects on human mitral valve interstitial cells ...

The effect of sublingual or intracoronary nitroglycerin (NTG) on luminal caliber in normal and diseased portions of epicardial coronary arteries was determined in 85 lesions from 57 typical patients with ischemic heart disease. Measurements were made from coronary angiograms, using a computer-assisted method and a carefully blinded protocol for analysis of the pre- and post- NTG angiograms. Lum...

Introduction: Renovascular hypertension is among the significant causes of severe in pediatrics. Primary therapeutic approaches, including drug therapy or angioplasty, are not always feasible, and their effectiveness variable. Meanwhile, several conditions leading to renal function impairment, artery stenosis, may represent respective kidney as an apparently non-functioning organ various imagin...

OBJECTIVE To determine the role of healed plaque disruption in the generation of chronic high grade coronary stenosis. METHODS Coronary arteries obtained at necropsy were perfuse fixed with formal saline for 24 hours at 100 mg Hg. The percentage lumen diameter stenosis was measured in each 3 mm segment containing a plaque, using the lumen size at the nearest histologically normal segment as t...
