Procedure used to identify coronary artery blockage. A catheter is introduced into the vascular system, and a radiopaque dye is infused. The heart is then visualized such that occluded vessels are apparent.
A procedure in which a long, flexible tube is inserted into cardiac vessels via a peripheral artery or vein; images produced from the procedure can isolate vessel blockage.
A diagnostic procedure that involves inserting a catheter into a vein or artery and advancing it under fluoroscopic guidance into the blood vessels or chambers of the heart. Contrast medium is injected to aid in visualization, and blood samples and pressure readings may be taken at different stages.
A minimally invasive procedure that involves threading a catheter (thin tube) through a blood vessel into the heart to obtain diagnostic information about the heart, coronary arteries (the arteries on the surface of the heart), and the aorta (the main artery leaving the heart). The doctor tracks the passage of the catheter through the circulatory system to the heart on a fluoroscope, an X-ray device that displays its image on a monitor. By injecting a special dye through the catheter, the doctor can take accurate X-ray pictures of the heart and its arteries.
Percutaneous intravascular insertion of a catheter into the cardiac ventricles, coronary arteries, or great vessels for diagnosis, assessment of abnormalities, interventional treatment, and evaluation of the effects of pathology on the heart and great vessels.
Passage of a thin, flexible tube into the heart to provide treatment for heart disease.
A diagnostic procedure involving the insertion of a slender tube into an artery or vein, guided by X-rays, to reach the heart. This technique allows for the evaluation of the functioning of the heart and blood vessels.
Cardiac catheterization is a diagnostic technique involving the insertion of a slender and sterile catheter, a flexible tube, into the heart through a vein or artery located in the arm or leg. This procedure is employed to diagnose and evaluate the severity of congenital heart disease and coronary artery disease. Furthermore, it aids in the diagnosis and treatment of specific heart valve disorders.
Throughout the course of this procedure, it is possible to measure the pressure within the heart chambers, collect blood and tissue samples for laboratory examination, or administer a radiopaque dye (a substance that appears opaque in X-rays) into the arteries. This dye facilitates the visualization of the heart cavities on an X-ray image.
This procedure typically induces minimal discomfort and is conducted using local anesthesia. A small opening is created in an artery or vein close to the surface of the skin, allowing for the insertion of the catheter into the blood vessel. The tube is then carefully threaded through the blood vessels until it reaches the heart.
