The computer is then used to reconstruct the transaxial, sagittal, and coronal images from the 3-dimensional distribution of radionuclides in the organ. The advantages of SPECT are that it can be used to observe biochemical and physiological processes as well as size and volume of the organ. The disadvantage is that, unlike positron-emission tomography where the positron-electron annihilation results in the emission of 2 photons at 180 degrees from each other, SPECT requires physical collimation to line up the photons, which results in the loss of many available photons and hence degrades the image.

A method of studying a drug or procedure in which both the subjects and investigators are kept unaware of who is actually getting which specific treatment.
A free radical gas produced endogenously by a variety of mammalian cells, synthesized from ARGININE by NITRIC OXIDE SYNTHASE. Nitric oxide is one of the ENDOTHELIUM-DEPENDENT RELAXING FACTORS released by the vascular endothelium and mediates VASODILATION. It also inhibits platelet aggregation, induces disaggregation of aggregated platelets, and inhibits platelet adhesion to the vascular endothelium. Nitric oxide activates cytosolic GUANYLATE CYCLASE and thus elevates intracellular levels of CYCLIC GMP.

Unexpected rapid natural death due to cardiovascular collapse within one hour of initial symptoms. It is usually caused by the worsening of existing heart diseases. The sudden onset of symptoms, such as CHEST PAIN and CARDIAC ARRHYTHMIAS, particularly VENTRICULAR TACHYCARDIA, can lead to the loss of consciousness and cardiac arrest followed by biological death. (from Braunwald's Heart Disease: A Textbook of Cardiovascular Medicine, 7th ed., 2005)
Platelet membrane glycoprotein complex important for platelet adhesion and aggregation. It is an integrin complex containing INTEGRIN ALPHAIIB and INTEGRIN BETA3 which recognizes the arginine-glycine-aspartic acid (RGD) sequence present on several adhesive proteins. As such, it is a receptor for FIBRINOGEN; VON WILLEBRAND FACTOR; FIBRONECTIN; VITRONECTIN; and THROMBOSPONDINS. A deficiency of GPIIb-IIIa results in GLANZMANN THROMBASTHENIA.

A nonparametric method of compiling LIFE TABLES or survival tables. It combines calculated probabilities of survival and estimates to allow for observations occurring beyond a measurement threshold, which are assumed to occur randomly. Time intervals are defined as ending each time an event occurs and are therefore unequal. (From Last, A Dictionary of Epidemiology, 1995)
A form of ventricular pre-excitation characterized by a short PR interval and a long QRS interval with a delta wave. In this syndrome, atrial impulses are abnormally conducted to the HEART VENTRICLES via an ACCESSORY CONDUCTING PATHWAY that is located between the wall of the right or left atria and the ventricles, also known as a BUNDLE OF KENT. The inherited form can be caused by mutation of PRKAG2 gene encoding a gamma-2 regulatory subunit of AMP-activated protein kinase.
Obstruction of flow in biological or prosthetic vascular grafts.
Non-invasive method of demonstrating internal anatomy based on the principle that atomic nuclei in a strong magnetic field absorb pulses of radiofrequency energy and emit them as radiowaves which can be reconstructed into computerized images. The concept includes proton spin tomographic techniques.
Subnormal intellectual functioning which originates during the developmental period. This has multiple potential etiologies, including genetic defects and perinatal insults. Intelligence quotient (IQ) scores are commonly used to determine whether an individual has an intellectual disability. IQ scores between 70 and 79 are in the borderline range.

An unusual case of bilateral subclavian-carotid artery graft occlusion with coronary steal syndrome managed in the cath lab. (2/4)

A 65-year-old man, s/p coronary bypass surgery (CABG) with left internal mammary artery (LIMA) to the left anterior descending (LAD) artery 12 years previously, presented to his local hospital with left upper extremity pain, dizziness, falls, and chest pain. At the outside hospital, a proximal total left subclavian occlusion was found and the patient underwent left subclavian artery to common carotid artery (SCA-CCA) bypass surgery. Shortly thereafter, the patient developed right subclavian thrombosis, and underwent right SCA-CCA bypass surgery. Twenty days later, coronary steal symptoms recurred; troponin levels were elevated and ultrasound exam revealed bilateral SCA-CCA graft occlusion. The patient was then transferred to a tertiary care facility with a diagnosis of non-ST elevation myocardial infarct (NSTEMI). A successful endovascular procedure was performed in the cardiac catheterization laboratory with the use of coronary chronic total occlusion (CTO) devices, to treat the coronary steal syndrome.  (+info)

Coronary subclavian steal from a left internal thoracic artery coronary bypass graft due to ipsilateral subclavian artery stenosis and an arteriovenous graft in a hemodialysis patient with left vertebral artery occlusion. (4/4)

Coronary subclavian steal syndrome is an unusual cause of myocardial ischemia, secondary to a reversed blood flow in patients with patent internal thoracic artery coronary bypass grafts. The causes of coronary subclavian steal are either ipsilateral subclavian artery stenosis or upper extremity arteriovenous hemodialysis fistula formation or both. This report involves a 68-year-old woman with left vertebral artery occlusion who developed severe coronary steal in the absence of vertebral subclavian steal due to left subclavian artery stenosis and an arteriovenous hemodialysis graft.  (+info)

Question - Experiencing debilitating balance problems. Has left vertebral artery occlusion. Taking Sotalol, Digoxin and Synthroid. What can be done?. Ask a Doctor about uses, dosages and side-effects of Digoxin, Ask a General & Family Physician
Background: Pulmonary regurgitation (PR) and the resultant right ventricular (RV) dilatation/dysfunction are important determinants of long-term outcome in patients with repaired tetralogy of Fallot (TOF). Although residual pulmonary stenosis (PS), which often coexists with PR, increases RV pressure load, it may help reduce PR and prevent RV dilatation. A certain degree of PS might even enhance RV function and thereby enhance left ventricular (LV) function via interventricular interaction. To test these hypotheses, we investigated pulmonary wave front behavior by wave intensity analysis (WIA) and interventricular interaction by pressure-volume relationships.. Methods: WI of the peripheral pulmonary arteries (PA) and LV pressure-volume relationships were computed during cardiac catheterization in 31 patients with repaired TOF and 28 control subjects. WIA yielded 3 major components: (1) compression and acceleration wave (W1), which reflects RV-PA interaction; (2) negative wave (WN), which ...

Coronary-subclavian steal syndrome can be described as unseting of angina pectoris related to diminished blood flow or retrograde blood flow because of the stenosis in left subclavian artery who intenal thoracic artery is used as an insitu bypass graft. Vasculary involvement in Behçet s disease has been reported and it usually appears as an aneurysm formation or stenosis. The involvement of the upper extremity arteries usually remains asymptomatic. But, in cases in which internal thoracic artery is used as an in situ graft for coronary artery bypass operations, associated involvement of the upper extremity arteries may result in diminished coronary perfusion and ischemic cardiac symptoms may be apparent. The patient with Behçet s disease had coronary artery bypass surgery in our department. Two years after surgery she readmitted with the complaints of angina pectoris increasing with the movement of her left arm, dizziness, paresthesia of the left arm and left subclavian artery stenosis was ...
This video demonstrates a left carotid to subclavian artery bypass. Due to increased use of aortic stent grafts that sometimes cover or compromise the orifice of the left subclavian artery, cardiothoracic surgeons need to be familiar with revascularization of the extremity.. ...
Subclavian artery stenosis (SAS) is a significant form of peripheral artery disease, which may be a marker of diffuse atherosclerosis and increased risk for cardiovascular events. SAS can lead to symptomatic ischemia affecting the upper extremities, the brain, and, in some cases, the heart. In general, asymptomatic subclavian artery disease is treated with medical therapy and invasive treatment is reserved for the more symptomatic patients. This article discusses the evaluation of four patients with varying presentations of subclavian artery disease. [Rev Cardiovasc Med.
The wave speed (c) and the arrival time of reflected wave (Trw) in the common left carotid artery and common left femoral artery have been evaluated in 70 healthy subjects, aged 35-55 years with a non-invasive method. Wave speed and the arrival time of reflected waves were determined with lnDU-loop and non-invasive wave intensity analysis (ndI) techniques, respectively. Diameter (D) was measured with ultrasound echo wall tracking and velocity (U) was obtained by ultrasonography. A statistical analysis has been carried out in order to establish a potential relation of c and Trw with gender and age in the study population. Subjects have been divided in two classes of age, one from 35 to 45 years and the other from 45 to 55 years. Results show that c and Trw in the femoral artery are higher than those in carotid, in both men and women (P | 0.001). Also, the distance of the reflection (L) site from the point of measurement is higher in the femoral than in the carotid artery. We did not find statistically

WEDNESDAY, Feb. 24, 2021 (HealthDay News) -- Hungry for good news on the pandemic? One epidemiologist believes Americans might reach herd immunity to the new coronavirus as soon as late spring.. Thats the view held by Suzanne Judd, a professor with the school of public health at the University of Alabama (UA) at Birmingham. To come to that conclusion, she reviewed recent research and data from her home state.. I really am starting to feel like we are seeing the edge of the woods, like we are seeing the light at the end of the tunnel, Judd said during a Wednesday media briefing.. According to the U.S. Centers for Disease Control and Prevention, herd immunity occurs when enough people in a community are protected from getting a disease because theyve already had the disease or because theyve been vaccinated.. Scientists largely believe enough people means 72% of the American public developing immunity to the coronavirus, Judd said, though she cautions that there is no magical number that ...

Cardiac Valve Replacement: When you replace a cardiac valve, a clot may form on the plastic-like valve, so anticoagulants are used to prevent from forming on that valve.. Atrial fibrillation: Patients who have atrial fibrillation means their atrium is not having a full contraction. That means the blood is never fully emptying out of the atrium. That residual blood could eventually form a clot and go down into the ventricles and go down into any of the arteries (coronary; carotid). So these people will be on continuous therapy.. ...

All patients with risk factors and those with a clinical presentation suggestive of PAD should undergo a comprehensive vascular exam from head to toe. The routine vascular exam should start with blood pressure measurement, performed in both arms to assess for significant subclavian artery stenosis. A systolic blood pressure difference of , 15 to 20 mmHg between the two arms should suggest subclavian artery stenosis. The carotid and subclavian arteries should also be auscultated for the presence for bruits. The abdominal aorta should be palpated to assess for abdominal aortic aneurysm. The abdominal vascular exam should include auscultation for bruits, which are occasionally present in patients with renal artery stenosis. Rarely, a bruit may also be heard in patients with celiac and mesenteric artery stenosis.. The lower extremity vascular examination should be performed with the patient in a supine position. The assessment should include inspection of the skin for discoloration, pallor, hair ...
The Ischemic Heart Disease (IHD) is characterized by an insufficient supply with blood of the myocardium usually caused by an artherosclerotic disease of the coronary arteries (coronary artery disease CAD). The IHD and its consequences have become a leading problem in the industrialized nations. The aim of this study was to evaluate a new diagnosing method, the cardiogoniometry, using two different classifying techniques: the method of linear discriminant function analysis (LDA) and the method of Support Vector Machines (SVM). Data of a group of 109 female subjects (62 healthy, 47 with IHD) were analyzed on the basis of extracted parameters from the three-dimensional vector loops of the heart. The LDA achieved an accuracy of 83,5% (Sensitivity 78,7%, Specificity 87,1%), whereas the SVM achieved an accuracy of 86% (Sensitivity 80,5%, Specificity 89,8%). It could be shown that cardiogoniometry, an electrophysiological diagnostic method performed at rest, detects variables that are helpful in ...

Atherosclerotic cardiovascular disease is the leading cause of death worldwide. To decrease mortality and morbidity in cardiovascular disease, the development of accurate, non-invasive methods for early diagnosis of atherosclerotic cardiac and vascular engagement is of considerable clinical interest. Cardiovascular ultrasound imaging is today the cornerstone in the routine evaluation of cardiovascular function and recent development has resulted in two new techniques, tissue velocity imaging (TVI) and speckle tracking, which allow objective quantification of cardiovascular function. TVI and speckle tracking are the basis for three new approaches to cardiac and vascular monitoring presented in this thesis: wave intensity wall analysis (WIWA), two-dimensional strain imaging in the common carotid artery, and the state diagram of the heart.. WIWA uses longitudinal and radial strain rate as input for calculations of wave intensity in the arterial wall. In this thesis, WIWA was validated against a ...

Noninvasively determined local wave speed ( c) and wave intensity (WI) parameters provide insights into arterial stiffness and cardiac-vascular interactions in response to physiological perturbations. However, the effects of incremental exercise and subsequent recovery on c and WI have not been fully established. We examined the changes in c and WI parameters in the common carotid artery (CCA) during exercise and recovery in eight young, healthy male athletes. Ultrasound measurements of CCA diameter and blood flow velocity were acquired at rest, during five stages of incremental exercise (up to 70% maximum work rate), and throughout 1 h of recovery, and noninvasive WI analysis [diameter-velocity ( DU) approach] was performed. During exercise, c increased (+136%), showing increased stiffness with work rate. All peak and area of forward compression, backward compression, and forward expansion waves increased during exercise (+452%, +700%, and +900%, respectively). However, WI reflection indexes ...
I have tachycardia, mitral valve prolapse, some pvcs. I take dixogin and it controls the rapid heart beat pretty well. My change of insurance meant a new cardiologist. I have seen her a few times for chest pains and she has said there was no cause of concern. A scan of my lungs ordered by another dr indicated anomalous origin of left vertebral artery. He didnt know anything about it so I emailed my new cardiologist. Her response stated it is something I was born with and it isnt dangerous. However, I did find limited information that was cause for concern. Supposedly it is crucial to advise surgeons before any neck surgery or angiogram about this condition and that it can mimic stroke symptoms and actually cause strokes, if I understand the jargon correctly.If this is true, then why didnt the cardiologist say anything? I also am concerned that my elderly mom who has already had two strokes and may at some point need an angiogram has not been diagnosed with this same condition. Should I ask ...
On Monday July 16, 2012, Elis cardiologist will take him before the surgery team to discuss his subclavian steal syndrome. He apparently has been going back and forth with some other doctors and gathering data to present to the team. There are several options and things to consider. Of course they always go from the most invasive to the least invasive. The most invasive is of course is full on heart surgery. This would be very risky since what they would do is bypass surgery. They would take an artery from somewhere else and put it in the spot where Elis artery doesnt exsist. This is where Elis original heart problem is though so if his aorta recoarcs then the vessel could tear and kill him almost instantly. This is EXTREMELY risky and most likely NOT the way they will proceed. Another option is to tie off the left vertebral artery (the artery that goes to Elis brain that now that is stealing the oxygenated blood from his brain). This apparently is normally done during the original surgery, ...
