Left Ventricular Output Angiography Blood Pressure (qualitative assessment of perfusion-related pressure dynamics during contrast injection)

What Is This Procedure Used For?

Left ventricular output angiography with blood pressure measurement is primarily used to diagnose coronary artery disease, evaluate heart valve function, or assess structural issues in the left ventricle. It may also help identify blockages or narrowing in coronary arteries that could restrict blood flow to your heart muscle.

How Is This Test Performed?

You’ll lie on an imaging table while a catheter is inserted into a blood vessel near your groin or wrist. A contrast dye is injected, and X-ray images capture blood flow through your heart’s left ventricle. Blood pressure is continuously monitored during the injection to evaluate perfusion dynamics.

What Should You Expect Before the Test?

You may receive sedation to keep you comfortable. Avoid eating or drinking for 6–8 hours before the procedure. Inform your doctor about any allergies, recent medications, or health conditions (e.g., bleeding disorders). Wear loose clothing and remove jewelry.

What Happens During Recovery?

You’ll rest in a recovery area for a few hours while the catheter is removed. Monitor your vital signs and report any pain, swelling, or unusual bleeding at the insertion site. Follow your doctor’s instructions for activity restrictions and follow-up imaging if needed.
