Diagnostic Procedures

Diagnostic procedures help provide information about your heart or lungs, the blood vessels that feed these organs, and your heart valves and aorta. This information helps your doctors make decisions about your care and treatment.

Left Heart Catheterization and Coronary Angiography (LHCC’s)

A sheath, or short tube, is inserted into the artery in your leg or wrist through which a flexible catheter is advanced to your heart. X-ray dye is injected to make your coronary arteries visible to check for blockages. Pictures are also taken to determine the strength of your heart muscle.

Right and Left Coronary Heart Catheterization and Coronary Angiography (RLHCC’s)

Along with looking at your heart, a sheath (short tube) is also inserted into the vein in your leg or neck and a catheter advanced to your lungs. This allows us to measure pressures in your heart and lungs.

Blockage Assessment

Several procedures, including ultrasound and flow measurements can be used to help your doctor find out how severe any blockages found in your coronary arteries might be.

Pulmonary Arteriogram (PA Gram)

Pictures of the arteries in your lungs are taken using a catheter. This catheter is inserted into a vein in your leg or neck and advanced to your lungs. X-ray dye is then injected to check for blood clots.

Peripheral angiography

If your doctor thinks you might have poor blood flow to your legs, we can take pictures of the blood vessels in your legs in a specially equipped procedure room.  Much like a heart cath, X-ray dye is injected though a small catheter directly into the blood vessels of your lower extremities to assess for narrowing or blockages.

Renal Arteriogram

If you doctor thinks the cause of your high blood pressure might be renal artery stenosis (narrowing or blockage of arteries leading to the kidneys) this procedure, we can get a look by inserting a small catheter in the artery in your leg and injecting a dye directly into the renal artery.
