Cardiopulmonary bypass
Cardiopulmonary bypassBypass of the heart and lungs as, for example, in open heart surgery. Blood returning to the heart is diverted through a heart-lung machine (a pump-oxygenator) before returning it to the arterial circulation. The machine does the work both of the heart (pump blood) and the lungs (supply oxygen to red blood cells). RELATED TERMS-------------------------------------- Bypass A surgical procedure designed to increase blood flow to an organ or extremity that has narrowing or blockage of the blood supplying artery. Examples include coronary artery bypass surgery, aortic replacement, ABI (aorta-bi-iliac), ABF (aorto-bi-femoral), and femoral-popliteal bypass) Heart The hollow, muscular organ responsible for pumping blood through the circulatory system. Lungs The main respiratory organs in the chest where blood is oxygenated. Surgery Treating diseases or other medical conditions by operating on a patient to remove or repair parts of the body. Blood The life-maintaining fluid which is made up of plasma, red blood cells (erythrocytes), white blood cells (leukocytes), and platelets; blood circulates through the body's heart, arteries, veins, and capillaries; it carries away waste matter and carbon dioxide, and brings nourishment, electrolytes, hormones, vitamins, antibodies, heat, and oxygen to the tissues. Circulation The flow of blood through the body. Includes the heart, arteries, veins and capillaries. Oxygen A chemical element essential for sustaining life. SIMILAR TERMS-------------------------------------- Cardene Cardene is a prescription or over-the-counter drug which is (or once was) approved in the United States and possibly in other countries. Active ingredient(s): nicardipine hydrochloride. Cardene sr Cardene sr is a prescription or over-the-counter drug which is (or once was) approved in the United States and possibly in other countries. Active ingredient(s): nicardipine hydrochloride. Cardex Clinic Jail Road The Cardex Clinic Jail Road is a hospital in Lahore, Punjab, Pakistan. Cardiac Pertaining to the heart. Cardiac aneurysm An outpouching of an abnormally thin portion of the heart wall. Cardiac aneurysms tend to involve the left ventricle because the blood there is under greatest pressure. Cardiac arrest The stopping of heartbeat. Cardiac Arrest When the heart stops beating suddenly and respiration (breathing) and other body functions stop as a result. Cardiac arrhythmia Irregular or abnormally slow or rapid beating of the heart. Cardiac Auscultation The use of a stethoscope to listen to the sounds the heart makes as it contracts and relaxes. Cardiac auscultation can be used to evaluate the heart rate, rhythm, and flow through the valves. Cardiac catheterisation A procedure in which a catheter (tube) is inserted into an arm or leg vein, through which it travels to the heart.˙ A dye is injected through the catheter and can be seen clearly by X-ray.˙ In this way, doctors can observe the inside of the arteries of the heart and check for abnormalities, especially narrowings or blockages. Cardiac catheterization A diagnostic procedure in which a tiny, hollow tube (catheter) is inserted into an artery to go to the heart in order to image the heart and blood vessels. Cardiac Catheterization An invasive imaging procedure that involves inserting a catheter into a blood vessel in the arm or leg, and guiding it to your heart with the aid of a special x-ray machine. Contrast dye is injected through the catheter so that x-ray movies of your valves, coronary arteries and heart chambers are taken. Cardiac catheterization is also called coronary angiography. Cardiac conduction system The electrical conduction system that controls the heart rate. This system generates electrical impulses and conducts them throughout the muscle of the heart, stimulating the heart to contract and pump blood. Cardiac defibrillator, implantable A device put within the body that is designed to recognize certain types of abnormal heart rhythms (arrhythmias) and correct them. Cardiac muscle A type of muscle with unique features only found in the heart. The cardiac muscle is the muscle of the heart and medically is called the myocardium ("myo-" being the prefix renoting muscle). Cardiac myocyte A heart muscle cell. Sometimes called a myocyte when it is understood that it is in the heart. Cardiac myxoma A benign tumor of the heart and the most common type of heart tumor in adults. Cardiac myxomas can appear in an isolated case or in families, sometimes as part of an hereditary syndrome called the Carney complex. Some families have the Carney complex variant as well as the trismus–pseudocamptodactyly syndrome (Hecht syndrome). A mutation in the perinatal myosin heavy chain causes this Carney complex variant, suggesting that mutated contractile proteins play a role in the development of cardiac myxomas. Cardiac output The amount of blood that goes through the circulatory system in one minute. Cardiac Output The amount of blood pumped by the heart each minute. Cardiac rehabilitation A structured program of education and activity guided toward lifestyle modification, increasing functional capabilities and peer support. Cardiac septum The septum of the heart is the dividing wall between the right and left sides of the heart. Cardiac tamponade A life-threatening situation in which there is such a large amount of fluid (usually blood) inside the pericardial sac around the heart that it interferes with the performance of the heart. The end result, if untreated, is low blood pressure, shock and death. The excess fluid in the pericardial sac acts to compress and constrict the heart. The word "tamponade" is direct from the French. The French verb "tamponner" means to plug up and, also, to smash into. Here the outpouring of fluid within the pericardial sac is, so to speak, smashing into the heart. Cardiac tamponade can be due to excessive pericardial fluid, a wound to the heart, or rupture of the heart. Also called pericardial tamponade. Cardiac ventricle One of the two lower chambers of the heart. Cardinoma Cardinoma refers to a malignant tumor of epithelial origin. Cardiogen-82 Cardiogen-82 is a prescription or over-the-counter drug which is (or once was) approved in the United States and possibly in other countries.

Cardiolite Cardiolite is a prescription or over-the-counter drug which is (or once was) approved in the United States and possibly in other countries. Active ingredient(s): technetium tc-99m sestamibi kit. Cardiologist A doctor who sees and takes care of people with heart disease; a heart specialist. Cardiology The clinical study and practice of treating the heart. Cardiomegaly Enlargement of the heart. Cardiomyopathy A disease of the heart muscle that causes it to lose its pumping strength. Cardiopathy Heart disease. A nonspecific term applicable to any and all diseases of the heart. Cardioplegia Paralysis of the heart, as may be done electively in stopping the heart during cardiac surgery.

Cardiopulmonary resuscitation The emergency substitution of heart and lung action to restore life to someone who appears dead. The two main components of cardiopulmonary resuscitation (CPR) are chest compression to make the heart pump and mouth-to-mouth ventilation to breath for the victim. Cardiopulmonary Resuscitation (CPR) CPR is a technique designed to temporarily circulate oxygenated blood through the body of a person whose heart has stopped. It involves assessing the airway; if necessary breathing for the person; determining if the person is pulseless; and if necessary, applying pressure to the chest to circulate blood. Cardioquin Cardioquin is a prescription or over-the-counter drug which is (or once was) approved in the United States and possibly in other countries. Active ingredient(s): quinidine polygalacturonate. Cardiotec Cardiotec is a prescription or over-the-counter drug which is (or once was) approved in the United States and possibly in other countries.
