Aortic Valve Stenosis Aortic Valve Stenosis is the narrowing or obstruction of the heart ’s aortic valve. The aorta is a large artery that originates in the left ventricle (lower chamber) of the heart. The narrowing and obstruction of the aortic valve prevents it from opening properly and blocks the flow of blood from the left ventricle to the aorta and onward towards the rest of the body. Aortic valve stenosis occurs in approximately 5 out of every 10‚000 people.1 It occurs more commonly

Thoracic Aortic Aneurysm: The Walking Time Bomb The human body is made up of many different systems that allow the body to function in a variety of ways. But in order to keep these systems working properly‚ the body needs nourishment and exercise. This should include a low-fat‚ low-cholesterol diet that will aid in the reduction of the plaque (fatty buildup) that narrows the arteries and aid in controlling high blood pressure and high cholesterol. Additionally‚ to lower many of the causes

just distal to the left subclavian artery. However‚ the constriction may be proximal to the left subclavian artery or rarely in the abdominal aorta. Aortic coarctation presenting during adult life‚ most frequently represents cases of recoarctation‚ following previous transcatheter or surgical therapy‚ or missed cases of native coarctation. Aortic coarctation may be recognized in the adult‚ usually because of systemic arterial hypertension and discrepant upper and lower extremity pulses. Patient

Student Name: Ashlie Collins Medical Diagnosis: Abdominal Aortic Aneurysm Definition: An abdominal aortic aneurysm is an enlarged area in the lower part of the aorta‚ the major blood vessel that supplies blood to the body. The aorta‚ about the thickness of a garden hose‚ runs from your heart through the center of your chest and abdomen. Because the aorta is the body’s main supplier of blood‚ a ruptured abdominal aortic aneurysm can cause life-threatening bleeding. Subjective Data:

The condition more often occurs in males compared to females. It occurs more frequently in above the age 60. When the aortic aneurysm is larger than size‚ it is more likely to rupture causing life-threating problems. This is a medical emergency requiring critical care. This complication is present in about 20% of the people affected with AAA. Another complication with AAA is aortic dissection in which the innermost membrane of the blood vessel ruptures due to the intense pressure causing blood to

Heart valve replacements are more common than most people think. In the United States it is said that over 99‚000 heart valve surgeries are performed yearly. The majority of the valve replacement surgeries are to replace or repair the mitral or aortic valve‚ since the left side of the heart works harder than the right. There are several types of valve disease‚ the two most common are valvular stenosis and valvular insufficiency. Valvular stenosis occurs when the opening of the valve is smaller

Aortic Dissection An aortic dissection is a tear in your aorta. The aorta is the main blood vessel that carries blood out of your heart to supply the rest of your body. It comes out of your heart and curves around‚ then goes down through your chest (thoracic aorta) and into your belly (abdominal aorta). The wall of the aorta has inner and outer layers. Aortic dissection occurs most often in the thoracic aorta. This is more likely to happen if the inner layer of the aorta has a weak spot or gets

Pain As an aortic aneurysm grows‚ it puts pressure on surrounding organs and tissue. Pain‚ often the first symptom‚ in the area of the chest‚ abdomen or back begins as a vague pressure or ache. Patients typically ignore initial pain symptoms‚ which prolongs diagnosis and appropriate medical intervention. The pain will change as the aneurysm enlarges. Patients experience throbbing‚ aching and gnawing pain in the abdomen and back. The National Heart Lung and Blood Institute reports pain symptoms
