atrioventricular valve into the right ventricle. The right ventricle contracts forcing the pulmonary valve to open leading blood flow through the pulmonary valve and into the pulmonary trunk. Blood is then distributed from the right and left pulmonary arteries to the lungs‚ where carbon dioxide is unloaded and oxygen is loaded into the blood. The blood is returned from the lungs to the left atrium by the pulmonary veins. From this step the blood in the left atrium goes through the left AV valve and into

oxygenated lungs to the rest of the body and organs. The hear contains two chambers‚ two atria and two ventricles. Oxygen-poor blood enters the heart through the vena cava and goes into the right atrium‚ the tricuspid valve opens to transport the blood into the right ventricle. The semilunar valves opens allowing for the blood to go into the pulmonary artery and transported to the lunges to become oxygenated. Oxygen-rich blood travels to the left atrium from the pulmonary veins‚ through the

PROCEDURE: The right groin was prepped and draped in the usual fashion. Seldinger technique was used‚ and a 6-French sheath was placed in the right femoral artery. A local anesthetic was used and sublingual nitroglycerin was given; no heparin was used. The left and right coronary arteries were selectively opacified in the LAO and RAO projections using manual injections

the ventricles‚ ventricular contraction begins. As the pressure in the ventricles increases‚ the AV valves close. This prevents the backward flow of blood. With continued contraction of the ventricles‚ blood leaves the heart via the aortic and pulmonary valves into the aorta and pulmonary artery respectively. At the end of the cardiac cycle‚ all the chambers relax‚ the aortic and pulmonary valves close‚ preventing the blood from flowing back into the heart. Atria begin to fill up with blood once

It is considered cost-effective in terms of INR regulation and safer with regards to complications. Moreover‚ analysis of selected subpopulations (heart valve implantation ‚ mitral and/or aortic mechanical ‚aortic and/or other aneurysm) shows that patient self-testing brings the most significant cost savings‚ especially for those oral anticoagulation therapy (OAT) patient segments .Test strips can be stored at room temperature.

An aortic aneurysm is a weak spot in the wall of the aorta‚ the primary artery that carries blood from the heart to the head and other extremities. I most cases people with aortic aneurysms in the chest area do not experience symptoms‚ but can have symptoms if the aneurysm gets bigger or causes pressure on the surrounding organs
