Cardiac Catheterization Services

Catheterization Procedures

Cardiac catheterization is a procedure which allows for detailed definition of cardiac problems and for the treatment of some of those problems. A catheterization is performed in a specialized radiology suite, usually under general anesthesia. This radiology suite is designed for the diagnosis and treatment of pediatric and congenital heart disease. Patients as small as newborns can be cared for in this way.

Procedure Details

During this procedure a long, thin tube (catheter) is introduced into an artery and vein. These catheters are advanced to the heart with the help of fluoroscopy or x-ray pictures displayed on a television screen. Blood pressure can be directly measured in all the chambers of the heart as well as the arteries and veins that come and go from the heart. Detailed measurements of the heart’s function are made which tells the Cardiologist how efficiently the heart pumps blood around the body. Contrast material can be injected into the blood stream providing detailed x-ray pictures of the heart’s chambers, valves, and large blood vessels. This is called angiography. Angiography along with assessment of heart function allows the Cardiologist to make definite diagnoses of heart and lung abnormalities. Cardiac catheterization procedures typically last between 2 and 3 hours. Patients will often be discharged from the hospital the same day and return to normal activities the following day.

Interventional cardiac catheterization is a type of catheterization procedure where treatment of certain heart problems can be performed with highly specialized catheters. Some interventional procedures are alternatives to surgery while others are palliative allowing for time before surgery is required. These treatments can be performed in the same catheterization suite and at the same time the diagnosis is confirmed by cardiac catheterization.

Some of the interventional procedures available at this time:

  • Closing of holes between the upper chambers of the heart (atrial septal defect).
  • Closing of extra blood vessel connections (patent ductus arteriosus).
  • Opening valves, such as the pulmonary or aortic valves, with balloon-tipped catheters.
  • Opening narrowed areas in arteries with balloon tipped catheters and/or stents.
  • Embolizing extra or redundant blood vessels in the lungs with coils

If you have any additional questions after your visit here, please feel free to call our office. Our goal is to provide reassurance that in the case where treatment is required, most treatment modalities are quite successful.

The Heart Center for Children is dedicated in providing a broad range of superior cardiac services from the prenatal period through adulthood. Our physicians, Dr. Jane M. Kao & Dr. Henry W. Kort are board certified in Pediatric Cardiology.
