46. Is visualization of totally occluded left anterior descending coronary artery on CT images before coronary artery bypasses grafting has beneficial effect?

Journal of the Saudi Heart Association, 2016
Computed tomography coronary angiography (CTCA) has emerged as an accurate anatomic method for detection of coronary arteries. The use of the left internal mammary artery (LIMA) to bypass the left anterior descending artery (LAD) is the “gold standard ...

Rationale and design of the Clinical Evaluation of Magnetic Resonance Imaging in Coronary heart disease 2 trial (CE-MARC 2): a prospective, multicenter, randomized trial of diagnostic strategies in suspected coronary heart disease [PDF]

, 2015
Background: A number of investigative strategies exist for the diagnosis of coronary heart disease (CHD). Despite the widespread availability of noninvasive imaging, invasive angiography is commonly used early in the diagnostic pathway.

Accuracy of Fractional Flow Reserve Derived From Coronary Angiography

Circulation, 2019
Background: Measuring fractional flow reserve (FFR) with a pressure wire remains underutilized because of the invasiveness of guide wire placement or the need for a hyperemic stimulus.

Coronary CT Angiography as an Alternative to Invasive Coronary Angiography [PDF]

, 2011
X-ray computed tomography (CT) was first invented in 1972 and its ability to obtain cross sectional images has proven to be a major advance in the field of medicine, garnering the Nobel Prize in medicine for Sir Godfrey Newbold Hounsfield and Allan McLeod Cormack in 1979.
