A Randomised Controlled Trial Assessing the Value of Computed Tomography Cardiac Angiography in Improving Patient Satisfaction and Reducing Contrast Load, Procedural Duration and Complications in Patients Who Had Previous Bypass Surgery Undergoing Coronary Angiography
A large number of patients with symptomatic ischaemic heart disease undergo coronary artery bypass grafting (CABG) to alleviate their symptoms and improve prognosis. Given the progressive nature of coronary disease, bypass grafts can narrow or block over time, leading to chest pain and the need for further invasive coronary angiography. Invasive coronary procedures in patients with bypass grafts can be more complicated due to the variation in bypass graft ostia. This can lead to longer procedure times, with higher doses of contrast and radiation and more discomfort for the patient. The aim of this study is to see if the use of computed tomography coronary angiography (CTCA) in patients with previous bypass grafts prior to invasive coronary angiography will help make their procedure safer and quicker.
