(heart catheterization) Procedure which includes insertion of a tubular device into the heart for recording of intracardiac and intravascular pressure, obtaining blood samples for chemical analysis, and cardiac output measurement, injecting or withdrawing fluids, etc.

(cardiac catheterization) A procedure in which a thin plastic tube (catheter) is inserted into an artery or vein in the arm or leg and then advanced into the chambers of the heart or into the coronary arteries. Catheterization can measure blood pressure within the heart and how much oxygen is in the blood. It's also used to get information about the pumping ability of the heart muscle. Catheters are also used to inject dye into the coronary arteries. Catheters with a balloon on the tip are used in the procedure called percutaneous transluminal coronary angioplasty.

(cardiac catheterization) A procedure to diagnose or treat heart problems; a long, thin, flexible tube is inserted into a blood vessel in the arm, neck, or upper thigh and maneuvered into the heart to evaluate various heart functions.

(cardiac catheterization) Passage of a small catheter through a vein or artery in an arm or leg or the neck and into the heart, permitting the securing of blood samples, determination of intracardiac pressure, and detection of cardiac anomalies.

(cardiac catheterization) Procedures in which placement of CARDIAC CATHETERS is performed for therapeutic or diagnostic procedures.

Cardiac catheterization is the passage of a catheter through peripheral arteries or veins into cardiac chambers, the pulmonary artery, and coronary arteries and veins.

Cardiac catheterization (kath-uh-tur-ih-ZAY-shun) is a procedure used to diagnose and treat certain cardiovascular conditions. During cardiac catheterization, a long thin tube called a catheter is inserted in an artery or vein in your groin, neck or arm and threaded through your blood vessels to your heart.

Cardiac catheterization, medical procedure by which a flexible plastic tube (catheter) is inserted into an artery or vein. It is used for injecting drugs for therapy or diagnosis, for measuring blood flow and pressure in the heart and central blood vessels, in performing procedures such as...
