- Pulmonary edema refers to the accumulation of fluid in the pulmonary alveolar and tissue spaces as a result of changes in capillary permeability and/or increases in capillary hydrostatic pressure.
- disseminated tuberculosis
- miliary tuberculosis

- exercise intolerance
- Exercise intolerance is the development of shortness of breath upon exertion.
- peripheral edema
- Peripheral edema refers to the accumulation of fluid in the intercellular tissue spaces of the legs and ankles.
- the patient had marked peripheral edema
- Marked peripheral edema is usually a manifestation of heart failure -- especially of the right ventricle.
- shortness of breath
- Shortness of breath is a common clinical manifestation of heart failure.
- cardiac enlargement and pulmonary edema
- Pulmonary edema refers to the accumulation of abnormal amounts of fluid in the extravascular spaces of the lungs. There are many causes for pulmonary edema. However, it is common clinical manifestation of left ventricular heart failure. Pressures rise in the left atrium and ventricle to compensate for the failure and this causes increased pressure in the pulmonary vasculature. Incrased pulmonary capillary pressure relative to the plasma oncotic pressure cause fluid to leave the vessels and enter the interstitial spaces of the lung.
- pleural effusions
- Pleural effusion is the presence of fluid in the pleural space. Increased hydrostatic pressure in the pulmonary vasculature, as seen in heart failure, is one cause of pleural effusion.
- 650 grams
- A normal heart weighs 300 grams (range: 270 to 360 grams).
- evidence of stenosis
- Aortic stenosis (calcification of the aortic valve) is the most common valve abnormality. Calcification of the valve leads to a reduced valve area. Increased pressure is thus needed from the left ventricle to pump blood into the aorta. Over time, the pressure-overloaded ventricle hypertrophies concentrically (increased ratio of wall thickness to cavity radius) in an attempt to reduce wall tension (review the Law of Laplace). Eventually, the left ventricle's contractile capacity is overwhelmed by the stiffness of the ventricle (due to hypertrophy) and pressure begins to increase through the left atrium and into the pulmonary vasculature. Increased pulmonary artery pressures then lead to right ventricular failure.
- insufficiency
- Aortic insufficiency refers to the inability of the aortic valve to close properly, thus allowing regurgitation of blood into the left ventricle during diastole -- i.e., volume overload. Disease of the aortic valve leaflets is a common cause of insufficiency.
- concentric hypertrophy
- Concentric hypertrophy is seen in pressure-overloaded hearts.
- (700 grams)

In lieu of cultures, a more rapid diagnostic test is the PPD--purified protein derivative of tuberculosis--test. PPD is injected under the skin of an individual and then the area is reexamined in 48-72 hours for signs of an inflammatory reaction. A positive test indicates previous exposure to M. tuberculosis.
- thoracotomy
- A thoracotomy is a surgical procedure in which an opening is made in the chest wall.
- emboli
- Plural of embolus. An embolus is something that blocks the blood flow in a blood vessel. It may be a gas bubble, a blood clot, a fat globule, a mass of bacteria, or other foreign body. It usually forms somewhere else and travels through the circulatory system until it gets stuck.
- iliofemoral venous thrombosis
- Thrombosis occurring in the deep veins of the legs is a common sequela seen post-operatively.
