What is a CT Coronary Angiogram | CTCA

A CT coronary angiogram or "CTCA" is a scan that records pictures of the heart arteries. Before the pictures are taken, dye is injected into a vein (usually in the arm). The dye highlights any blockages in the coronary arteries, helping to diagnose coronary artery disease.Current literature suggests CTCA may have greatest utility in patients where the probability of coronary disease is low or intermediate due to high negative predictive value - i.e. it is an excellent ‘rule-out’ test. There are some limitations with the CT scan that need to be considered and requirements to slow the heart rate so that the quality of the images is high. Professor Barlis discusses some of the uses of the CT scan and how it may provide relevant details about the arteries around the heart.

Excellent video. Short but extremely informative and explained very well.

My mother is currently getting this done. I have seen many PCI angiograms before (RN), but never seen a CTCA done. Now I know what it is and what’s involved, cheers!

Thank you for that very informative information, you're a champion

Have recently found your excellent channel. Very informative particularly for those of us who who are concerned about heart disease and have had a stent such as I have. You seem to be up to date on the latest treatments for heart disease. Is there a way way or is there research into the use of laser or ultrasound or a vacumn to suction arteries of plaque or blockage? I have an elevated calcium score and I have had two stents, one about 10 years ago and a second one about two years ago. I have an excellent life style and diet. I exercise regularly, never smoked and have not used alcohol in many years but still have concerns because of age and family history. Thank you again for your channel. Blessings

I’m getting this done pretty soon I keep telling my cardiologist I’ll be having mini heart attacks that last 20 seconds I did a Lexi scan last year. It was normal, but my EKG always show abnormal. by the time they do the test, they don’t see anything by the time I go home call paramedics it shows I had heart attack. I always tell my doctor put me on a heart monitor. That way you can see it. He don’t recommend that.

Hi I had my angiogram last month I was diagnosed ischemia heart disease and when the doctor had a look at my vessels they were normal does the angiogram show small blood vessels also does it show oxygenated blood to the heart

I had a CT Angio Chest w Contrast. Do I need a Coronary CT, too? From my understanding these tests are different from each other. Is there an advantage to one over the other?

[@sharontwombly5205]

i am allergic to betadine so can i do it. my allergy is extreme like i hard to wake up my surgeon had hard time getting me off vent. did not at that time my allergy was that bad but of course many doctors like to debate it. i would like to hear your thoughts.

[@davie2983]

I am concerned about the dye. I would not prefer a procedure without the dye.

[@shahlajaved6676]

this Test will know if I had a Heart attack ? Pls reply

[@Corkfish1]

More revealing than a Calcium Score??

[@chrisrogers1092]

Yes

As an Engineer, why not do preemptive bypasses? Nice new arteries for the heart? Solve the problem instead of treating the problem.

They make more money when they treat the problem. You are a returning customer when they treat the problem. You are a one time customer when they solve the problem.
