Computed tomographic coronary angiography (CTCA) has gained acceptance as a noninvasive method to assess patients with suspected coronary artery disease (CAD). Researchers assessed its “real-world” performance, versus the gold standard of invasive coronary angiography (ICA), at four centers, using equipment from two different vendors in 169 patients (mean age, 61; mean pretest probability for CAD, 47%). Patients were scheduled for ICA because of valvular, aortic, or congential heart disease or cardiomyopathy (low probability for CAD) or because of chest pain (intermediate probability for CAD). For each patient, 64-slice multidetector CTCA was performed within 10 days of standard ICA. The studies were read independently by two-person teams o…
