Pulmonary artery

Description of Disease Transposition of the great arteries is a life threatening congenital heart defect. In transposition of the great arteries, the two main arteries, the aorta and the pulmonary artery, are reversed. These arteries are responsible for carrying blood away from the heart through the left or right ventricle depending on whether the blood has been oxygenized or not. In a normal heart, there is a constant blood flow pattern in which blood is cycled from the body to the heart, the…

heart failure, occurs when your heart muscle doesn't pump blood as well as it should. Certain conditions, such as narrowed arteries in your heart (coronary artery disease) or high blood pressure, gradually leave your heart too weak or stiff to fill and pump efficiently.” Web. . January 12, 2016 There are contributing factors that can lead to heart failure such as coronary artery disease, diabetes, obesity, and high blood pressure. Management of these diseases such as daily exercise, weight…

and can cause dyspnea (Hoette et al., 2010). On chest CT, enlargement of the main pulmonary artery to a diameter of 29 mm or greater was associated with a high sensitivity (84%), specificity (75%), and positive predictive value (95%) in a heterogeneous group of patients with chronic lung disease (Tan et al., 1998). However, CT findings may be less reliable in patients with interstitial pulmonary fibrosis (IPF) (Zisman et al.,…

elevated troponins and elevated ST segments on EKG. A 2D echocardiogram showed left ventricular apical akinesis with basal hyperkinesia. He had a coronary angiogram completed, and it showed no stenotic arteries, however they also injected ergonovine which appeared to cause a right coronary artery spasm. The patient was treated with calcium channel blockers and nitrates. A follow up two weeks later showed normal wall motion as well as a sigmoid septum, and normal systolic function. He was…

need to understand some of the differences in veins and arteries. The arteries in the systemic system, deliver oxygenated blood from the heart, in a high pressure low volume stream to the capillaries found throughout the body. The systemic veins carry the deoxygenated blood from the capillary beds in a low pressure, high volume, valve controlled flow, back to the heart. From there, the heart pumps the deoxygenated blood through pulmonary artery to be taken to the lungs to replenish the oxygen…

9. If undetected and untreated, how might this baby’s condition have progressed? (1 point) If this is left untreated she could develop high blood pressure in the lungs (pulmonary hypertension). This happens when too much blood circulating through the heart’s main arteries through a patent ductus arteriosus can lead to pulmonary hypertension which can cause permanent lung damage. A patent ductus arteriosus can eventually lead to heart failure. This happens because the heart is enlarged and…

surveillance and prevention program no matter what type of dog. The parasite is commonly called “heartworm”. It gets its name from the location where it is found most often; the heart. Nevertheless, it has been known to be in the pulmonary arterial system (lung arteries) and can have further damaging affects to lung vessels and…

pressure 15 cmH2O, FiO2 0.4-0.6, fresh gas flow 1-1.5 L/min. Normocapnia was maintained throughout the surgery. CVP remained stable at 16-22 mmHg. Surgery included diagnostic cerebral arteriography with coil embolization of left posterior communicating artery aneurysm, and placement of right external ventricular drain (EVD). The estimated blood loss during the procedure was minimal (less than 50 ml), and the total intraoperative fluid intake was 500 ml of crystalloids. The patient remained…

Heart Disease in Women and their Unique Symptoms of a Heart Attack Introduction: Heart attacks are a very serious condition of the human body that require immediate attention. Heart attacks are known in the medical community as myocardial infarctions: myo- means muscle, cardio- means heart, -al means pertaining to; infarct means death of tissue (med term book). The parts come together as: tissue death pertaining to heart muscle (med term book). Each year, around one and half million cases of…

the heart’s left and right atria and a plastic model is placed into chest inorder to determine the proper placement for the artificial heart.A special type of synthetic tissue is then cut up by suregons and sewn to the atora (artery to the body) and the pulmonary artery (artery to the lungs) This synthetic is used to help connect the artificial heart to the remaning parts the natural heart. The artificial heart is then placed into the chest and connected by quick connects which are similar to…
