Coronary artery disease (CAD) is a prominent cause of death for all ages in the United States. In general‚ there is a buildup of plaque inside the coronary arteries. CAD is described as a complex chronic inflammatory disease‚ regarded as plaque accumulation resulting in reduction of oxygen-rich blood flow to the heart (Sayols-Baixeras‚ Lluis-Ganella‚ Lucas‚ & Elosua‚ 2014). “Plaque is made up of deposits of cholesterol and other substances in the artery” (Centers for Disease Control and Prevention

today so buckle up and enjoy the ride. We begin our journey in the femoral artery of this extremely fit female subject‚ Miss Waters. (Be sure to thank her when the ride has come to an end.) Okay‚ here go. The femoral artery is very large in size and is located in the inner part of the thigh. A femoral artery can often be palpitated and used as a catheter access artery. It is an extremely amazing thing‚ the femoral artery. It is an access point for catheters that can travel all the way to the heart

carotid arteries. So why do an estimated 700‚000 people get carotid artery disease each year‚ And why do more than 130‚000 people die of strokes each year?1 these questions will be answered in order to provide a better understanding of the carotid arteries and their importance. [change slide] Oxygenated blood is carried from the heart to the face and brain by the carotid arteries‚ one on each side of the neck. [change slide] The carotid arteries bifurcate and become the internal carotid artery (ICA)

circulation needs to be changed because now the baby must breathe by own using its lungs. Increased level of pO2 causes spasm of the umbilical arteries and‚ as follows‚ decreased venous return to the right atrium. The vascular resistance in the lungs drops and all cardiac output flows through the pulmonary vessels now. Increased return to the heart through the pulmonary veins causes the raised pressure in the left atrium. As result of the changes described above foramen ovale is closed because the pressure

ventricular septal defect (VSD)‚ which is a hole between the left and right ventricles. The second is an overriding aorta. The aorta‚ instead of rising from the left ventricle‚ is located further to the right‚ directly above the VSD. Third‚ there is pulmonary valve stenosis. The narrowing of the pulmonic valve induces the right side of the heart to work harder to push blood through it and results in the fourth defect‚ right ventricular hypertrophy (Children’s MN‚ 2012).

Coronary heart disease is the buildup of plaque in the heart’s arteries that could lead to a myocardial infarction. However‚ coronary heart disease‚ or CHD‚ is actually a result of coronary artery disease‚ or CAD. With coronary artery disease‚ plaque accumulates within the walls of the coronary arteries until the blood flow to the heart is limited‚ causing ischemia. It may be chronic‚ caused by narrowing of the coronary artery over time. It can be acute‚ resulting from a sudden rupture and formation

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 of Optiray. A ventriculogram was done in the RAO projection with the use of a 6-French pigtail catheter
