Cardiac Cath Vs Ct Angiogram
Which procedure is more useful to detect artery blockage, angiography, CT angiogram, or cardiac catheterization and why?
Ct uses xrays taken an 360 degrees combined with a computer to see"inside" the body. The table moves as the xray tube and detectors spin around the patient 10 times a second or more! The image shows excellent soft tissue detail, enhanced with injection of intravenous contrast or oral contrast. This way the body is shown in slices, in any plane, usually axially, but ...Read more
Depends on situation: Nuclear stress test involves looking at perfusion of heart for defective areas representing coronary artery disease looking for areas of permanent damage versus areas that are reversible possible related to area of coronary narrowing. Coronary ct angiogram looks at anatomy of coronary arteries looking for areas of narrowing and blockage. Answer depends on information physician needs and insurance. ...Read more
I'm 21 and have had problems with angina-like pain all mylife. More recently, I have started getting palpitations and breathlessness. I have had ekgs, holter, echos, bloods and cardiac CT angiogram done. Have I left any bases uncovered?
Look elsewhere: You seem hung up on cardiac causes but you haven't said anything about consultation with a gastroenterologist to look at your esophagus. Esophageal spasm can mimic angina and can even get better with nitroglycerin. You should also consider whether or not this is an anxiety or panic attack. ...Read moreSee 2 more doctor answers

What is the negatice predictive value of a coronary 64 slice ct angiogram Done at a reputable center... If the calcium score was 0 and CCTA negative??
Ct vs cath: In simplest terms the ct angiogram would be safer than a coronary angiogram, however, they are usually used in different circumstances. The ct angiogram is useful as a screening tool to see if coronary disease is present. A cardiac catheterization is performed when a patient has an acute coronary syndrome or a myocardial infarction to evaluate coronary disease, or even treated. ...Read moreSee 1 more doctor answer
Both safe: Both also have risks such as radiation and contrast usage. Coronary arteriography has small bleeding risk at puncture site. Need to get the right test for your problem. Coronary arteriography is the gold standard. ...Read more
Coronary CT angiogram shows extremely high calcium score of 4242 and ~ 70% blockage one artery. Next step cath angio. Should I consider atherectomy?
NO: You need a coronary angiogram-depending what it shows, you may need revascularization. Depending on location and extent, you may need surgery. Otherwise, balloon angioplasty followed by stenting is the treatment of choice. Atherectomy has a very limited and specific indication. If you need it, your interventionalist is the one to make the call. ...Read moreSee 2 more doctor answers
If a coronary ct angiogram Done at mayo clinic in Arizona says I have 0 plaque is it very accurate? My heart rate was 50, how good is that test? Help.
Accurate: CT angio is accurate and your heart rate of 50 was really in the ideal range for the test. If you still have concerns may want to have a stress test that will show changes related to your heart related to higher work loads than at rest. Unless you have some familial lipid/cholesterol problems you are still fairly young to show plaques, though if you smoke you will accelerate their appearance. ...Read moreSee 1 more doctor answer
Will a CT angiogram of the coronary arteries reveal a pulmonary embolism or other lung disease and is it harmful to have 2 CT scans in the same month?
It might: A CT angiogram or the coronaries might show a pulmonary embolism, provided that the radiologists obtained full field of view reconstructions (some do not) and the pulmonary embolism is not higher or lower than the field of view. Most often, the answer would be yes, a significant PE would be identified on this type of scan. Having two ct's in the same month is not optimal, but likely of no harm. ...Read more
How many cardiac cta (computed tomography angiogram) procedures are performed annually in small hospitals?
Can you have a cornary calcium score of 0 and still have blockage? This was on a, CT angiogram 2 years ago...
I go back to my doctor (i had a pe) for a CT angiogram to see if the clot has dissovled - if it hasn't, what's the next step?
Likely nothing: Assuming that you have been taking your anticoagulation for the correct amount of time, the pe is likely gone. We do not routinely repeat ctpagrams to see if the clot is gone unless it was an extremely large one. You have to weigh the risks of the radiation (don't know your age) with the benefits. I don't know how long it has been but most clots dissolve on their own. ...Read moreSee 1 more doctor answer
This is a procedure where narrow, flexible tubes are inserted into a peripheral artery through a cut in the skin, and advanced to the heart. Dye can be injected through the catheters into the arteries of the heart to look for blockages ("angiogram"), or to measure pressure within the cardiac chambers ("right heart cath"). Arteries can be opened with balloons/stents at the ...Read more
