BACKGROUND Traumatic hemopericardium remains a rare entity; it does however commonly cause cardiac tamponade which remains a major cause of death in traumatic blunt cardiac injury. OBJECTIVES We present a case of blunt chest trauma complicated by cardiac tamponade causing cardiac chamber equalization revealed by reflux of contrast. CASE REPORT A 29-year-old unidentified male suffered blunt ...
Change in cardiac output and blood shift induced by standing were evaluated successively in 18 subjects using external radioisotope counting techniques. Presence of a linear correlation was demonstrated between these 2 hemodynamic variables. When a marked decrease in cardiac output was revealed, blood shift was relatively slight in any subject, and vice versa. This finding was considered to sug...
Background: Central Venous Catheters (CVCs) are flexible long catheter that inserted in central veins may placement subclavian, internal jugular and femoral vein or arm. Aims of the study: to evaluate knowledge for nursing staff concerning venous care al-Nasiriyah cardiac center. Methodology: A descriptive cross-sectional design was carried out at AL-Nasiriyah Cardiac Center during period from ...
BACKGROUND AND PURPOSE Contrast-enhanced head and neck MRA may be degraded by venous stasis and reflux of contrast into the jugular veins. The purpose of this study was to evaluate the relationship between venous stasis and reflux and the side of injection and other causal factors. MATERIALS AND METHODS One hundred twenty-six consecutive patients (94 males and 32 females) who underwent contra...
BACKGROUND We compared cardiac electrophysiological indicators and regional expression levels of cardiac hyperpolarization-activated cyclic nucleotide-gated (HCN) channels between adult and aged dogs to identify possible mechanisms of age-related atrial fibrillation. MATERIAL/METHODS Corrected sinus node recovery time (SNRTc) and effective refractory period (ERP) of the atrium and pulmonary v...
Anomalous pulmonary venous drainage, expressed in the simplest of terms, means that pulmonary veins fail to enter the left auricle. If one or two pulmonary veins fail to enter the left side of the heart there may be no outward signs of cardiac disability and the patient leads a relatively normal life. Even if one half of the oxygenated blood enters directly or by venous channels into the right ...
giant left atria are defined as those measuring larger than 8 cm and are typically found in patients who have rheumatic mitral valve disease with severe regurgitation. enlargement of the left atrium may create compression of the surrounding structures such as the esophagus, pulmonary veins, respiratory tract, lung, inferior vena cava, recurrent laryngeal nerve, and thoracic vertebrae and lead t...
background: cardiac rehabilitation is known as a powerful non-pharmacological approach for improving functional capacity, and left ventricular systolic function; however, some limited data have suggested an attenuation of the decline in diastolic function with this program. this study investigated the effect of high intensity aerobic exercise following coronary artery bypass surgery (cabg) on d...
conclusion the open-cell stent is effective and its performance is higher than that obtained with the closed-cell stent for treating central vein stenosis or occlusion in hemodialysis patients. results for the open-cell stent group, 159 patients were diagnosed as central vein stenosis and 98 were occlusion. for the closed-cell stent group, 78 were stenosis and 66 were occlusion. there were two ...
