| 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 | 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, 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) |
| anterior coronary plexus | The part of the cardiac plexus that accompanies the coronary arteries on the anterior aspect of the heart. (05 Mar 2000) |
| atherectomy, coronary | Percutaneous transluminal procedure for removing atheromatous plaque from the coronary arteries. Both directional (for removing focal atheromas) and rotational (for removing concentric atheromatous plaque) atherectomy devices have been used. (12 Dec 1998) |
| valve of coronary sinus | A delicate fold of endocardium at the opening of the coronary sinus into the right atrium. Synonym: valvula sinus coronarii, coronary valve, thebesian valve. (05 Mar 2000) |
| percutaneous transluminal coronary angioplasty | Percutaneous transluminal angioplasty of coronary artery or arteries. (05 Mar 2000) |
| right coronary artery | <anatomy, artery> Origin, right aortic sinus; distribution, it passes around the right side of the heart in the coronary sulcus, giving branches to the right atrium and ventricle, including the atrioventricular branches and the posterior interventricular branch. Synonym: arteria coronaria dextra. (05 Mar 2000) |
| right coronary artery branches | <radiology> Conus branch, branch to S-A node, acute marginal branches, branches to posterior left ventricle, branch to A-V node, posterior descending artery (patent ductus arteriosus, 90%), hence, right coronary a. Is usually dominant (12 Dec 1998) |
| circumflex branch of left coronary artery | <anatomy, artery> Terminal branch (with anterior interventricular artery) of left coronary artery which runs to left and then posteriorly in the coronary groove supplying atrial and ventricular branches. Synonym: ramus circumflexus arteriae coronariae sinistrae. (05 Mar 2000) |
| coronary | <anatomy, cardiology> A term applied to vessels, nerves, ligaments, etc. The term usually denotes the arteries that supply the heart muscle and, by extension, a pathologic involvement of them. Origin: L. Corona, Gr. Koron = encircling in the manner of a crown (18 Nov 1997) |
