You should figure out transportation from the hospital if you’re going home the same day.What happens during a coronary angiogram?In general, you can expect the following during a coronary angiogram:You change into a medical gown and lie on your back for the procedure.A healthcare provider gives you medicine that makes you feel relaxed (a sedative) through an IV. But you’ll still be awake enough to follow instructions. For example, they might have you cough or hold your breath for a couple of seconds.An electrocardiogram (EKG) will monitor your heart rhythm during the procedure.A provider gives you local anesthesia to numb the area where they’ll access an artery. This is usually in your groin or arm. You may feel pressure in this area during the procedure, but you shouldn’t feel pain.A cardiologist accesses a blood vessel with a needle. They slide a sheath (or tube) over the needle and into a large artery.The cardiologist passes wires and catheters through the tube to get to the coronary arteries on the surface of your heart. You won’t feel the tube going through your blood vessels.An X-ray machine rotates around you (called fluoroscopy). It allows the cardiologist to see where the catheter is going from all angles.Once your provider gets the catheter into your heart or aorta, they put a special dye into the tube. They look at X-rays to watch the dye go through your artery. For a few seconds, you might feel flushed or like you need to pee.The cardiologist can see if anything (like cholesterol or plaque) is getting in the way of blood going through your coronary arteries.If the cardiologist sees something blocking your blood flow, they may be able to clear the blockage right away with a balloon. This is called an angioplasty. They can then then place a stent to keep your artery open.If this isn’t possible or the cardiologist thinks a different procedure later is best, they’ll end the coronary angiogram.A coronary angiogram typically takes 30 to 50 minutes. But this can vary.What to expect after a coronary angiogramWhen the procedure is done, the cardiologist will take out the catheter.

Serious complications are rare.AdvertisementThe risks of a coronary angiogram include:Abnormal heartbeats (arrhythmia)Allergic reaction to the contrast dye or anestheticAn injured blood vesselBlood clotsCardiac tamponade (pressure on your heart from fluid building up around it)Heart attackKidney damage, including the need for dialysisLow blood pressurePain, bleeding or infection where a needle or catheter went into your skinStrokeYou’re more likely to have complications if you:Are over 65 yearsHave diabetesHave kidney diseaseTalk to your healthcare provider if you have questions about these risks.Care at Cleveland ClinicCardiology CareCardiology Care for ChildrenMake an AppointmentResults and Follow-UpWhen should I know the results of the test?You may be able to see your X-rays while the cardiologist does the test.
