| catheterization | Use or insertion of a tubular device into a duct, blood vessel, hollow organ, or body cavity for injecting or withdrawing fluids for diagnostic or therapeutic purposes. It differs from intubation in that the tube here is used to restore or maintain patency in obstructions. (12 Dec 1998) |
|---|---|
| catheterization, central venous | Placement of an intravenous catheter in the subclavian, jugular, or other central vein for central venous pressure determination, chemotherapy, haemodialysis, or hyperalimentation. (12 Dec 1998) |
| catheterization, peripheral | Insertion of a catheter into a peripheral artery, vein, or airway for diagnostic or therapeutic purposes. (12 Dec 1998) |
| catheterization, swan-ganz | Placement of a flow-directed catheter (developed by cardiologists swan and ganz) for measuring pulmonary arterial pressures. The catheter is introduced into the venous system via the basilic, internal jugular, or subclavian vein, and is guided by blood flow into the superior vena cava, the right atrium and ventricle, and into the pulmonary artery. (12 Dec 1998) |
| heart catheterization | Procedure which includes placement of catheter, recording of intracardiac and intravascular pressure, obtaining blood samples for chemical analysis, and cardiac output measurement, etc. Specific angiographic injection techniques are also involved. (12 Dec 1998) |
| differential ureteral catheterization test | A study performed to determine various functional parameters of one kidney compared to the contralateral kidney; ureteral catheters are inserted at cystoscopy into the ureter or renal pelvis bilaterally, and simultaneous measurements are made of urine flow rate, insulin, or PAH (if infused), endogenous creatinine, or various urinary solutes. Synonym: differential renal function test, split renal function test. (05 Mar 2000) |
| urinary catheterization | Employment or passage of a catheter into the bladder (urethral c.) or kidney (ureteral c.) for therapeutic or diagnostic purposes. (12 Dec 1998) |
| abnormal cleavage of cardiac valve | Congenital malformation of a valve leaflet with a defect extending from the free margin. (05 Mar 2000) |
| anterior cardiac veins | Two or three small veins in the anterior wall of the right ventricle opening directly into the right atrium independently of the coronary sinus. Synonym: venae cordis anteriores. (05 Mar 2000) |
| area of cardiac dullness | A triangular area determined by percussion of the front of the chest; it corresponds to the part of the heart that is not covered by lung tissue. (05 Mar 2000) |
| 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) |
