In this way, oxygenated blood reaches every part of the heart.Venous blood from the heart is collected into the cardiac veins: middle, posterior, and small. They are all tributaries to coronary sinus–a large vessel that delivers deoxygenated blood from the myocardium to the right atrium.We’...
thrombosis- the formation or presence of a thrombus (a clot of coagulated blood attached at the site of its formation) in a blood vessel coronary heart disease- a heart disease due to an abnormality of the arteries that supply blood and oxygen to the heart ...
spasm - (pathology) sudden constriction of a hollow organ (as a blood vessel) bronchospasm - a spasm of the bronchi that makes exhalation difficult and noisy; associated with asthma and bronchitis cardiospasm - a spasm of the cardiac sphincter (between the esophagus and the stomach); if the ...

So, it should not hurt when the catheter ispassed into the blood vessel. The doctor gently pushes the catheter up theblood vessel towards the heart. Low dose x-rays are used to monitor theprogress of the catheter tip which is gently manipulated into the correctposition. You may be able ...
Obstructive CAD was defined at both CTA and ICA as > 50% stenosis in at least one major coronary vessel. In addition, for CTA each segment of the American Heart Association (AHA) 17-coronary segment model was assessed for interpretability, and interpretable segments were evaluated for the...
Subsequently, lipoproteins enter the blood vessels and deposit on the intima of the vessel wall. Eventually, macrophages in the body tissues proliferate in response to clearance reactions and in conjunction with vascular smooth muscle cells, forming atherosclerotic plaques, which accelerate the progression...
Coronary blood flow is crucial for delivering oxygen to the myocardium and is heavily governed by numerous physiological factors including cardiac output, heart rate, ventricular pressure, coronary perfusion pressure, vessel diameter, aortic valve area, disease status (such as AS or CAD) as well as...
Gas sensing measurements were made at room temperature using a self-built Instant gas sensing platform (IGSP). A 1.2-L vessel was used as a vapor-sensing chamber. During the experiment, different volumes of the gas solution to be tested were directly fed into the vessel through a hole locat...
Although some normal lung uptake may often be seen, increased rest uptake occurs in heavy smokers and patients with underlying lung disease and heart failure. Increased uptake with exercise is suggestive of three-vessel disease. This pattern has been better validated with Tl-201. The right ventricl...
