| Carden's amputation | Transcondylar amputation of the leg, the femur is sawed through the condyles just above the articular surface. (05 Mar 2000) |

| Carden, Henry | <person> British surgeon, +1872. See: Carden's amputation. (05 Mar 2000) |
| cardenolide | A class of cardiac glycosides containing a five-membered lactone ring (e.g., the Digitalis glycosides). (05 Mar 2000) |
| cardenolides | C(23)-steroids with methyl groups at c-10 and c-13 and a five-membered lactone at c-17. They are aglycone constituents of cardiac glycosides and must have at least one double bond in the molecule. The class includes cardadienolides and cardatrienolides. Members include digitoxin and digoxin and their derivatives and the strophanthins. (12 Dec 1998) |
| cardia | The part of the stomach immediately adjacent to and surrounding the cardiac opening of the oesophagus, distinguished only by the presence of the cardiac glands, and lacking acid (parietal) and pepsin (chief) cells. (12 Dec 1998) |
| cardiac | <cardiology> Pertaining to the heart. Origin: L. Cardiacus from Gr. Kardiakos (16 Dec 1997) |
| cardiac accident | Sudden cardiac catastrophe, such as may result from coronary occlusion. (05 Mar 2000) |
| cardiac albuminuria | Albuminuria caused by congestive heart failure. (05 Mar 2000) |
| cardiac alternation | The occurrence of any cardiac phenomenon every other beat. (05 Mar 2000) |
| cardiac aneurysm | Thinning, stretching, and bulging of a weakened ventricular wall, usually as a result of myocardial infarction; rarely postinflammatory or congenital. Synonym: mural aneurysm, ventricular aneurysm. (05 Mar 2000) |
| cardiac arrest | This refers to the complete cessation of cardiac activity (heartbeat). (27 Sep 1997) |
| cardiac arrhythmia | A disturbance the electrical activity of the heart that manifests as an abnormality in heart rate or heart rhythm. Patients with a cardiac arrhythmia may experience a wide variety of symptoms ranging from palpitations to fainting. (27 Sep 1997) |
| cardiac asthma | An asthmatic attack, the bronchoconstriction being secondary to the pulmonary congestion and oedema of left ventricular failure. (05 Mar 2000) |
| cardiac ballet | Short runs of cardiac dysrhythmia consisting of uniform sequences of repetitive multiform extrasystoles; so called from its undulating appearance, originally described by Bellet. See: torsade de pointes. (05 Mar 2000) |
| cardiac blood pool imaging | This noninvasive test uses radioactive tracers to delineate the hearts chambers and major vessels. It may be used to detect a heart attack, heart muscle function and coronary artery disease. The patient receives a radioactive tracer by injection (into a vein) and then the heart is imaged using a gamma camera. The heart is imaged before and after exercise. This test may be used to detect and evaluate atrial septal defect, dilated cardiomyopathy, congestive heart failure, cardiomyopathy, Lyme disease (secondary), mitral stenosis and superior vena cava syndrome.
