Correction to: Predicting the Physiological Effect of Revascularization in Serially Diseased Coronary Arteries: Clinical Validation of a Novel CT Coronary Angiography–Based Technique

Background: Coronary artery disease (CAD) morbidity and mortality increasing day by day in India as well as worldwide. Coronary arteries visualization by using invasive catheterization angiography is still using as a front-line diagnostic tool to evaluate the patients with CAD. 128 slice dual source CT improves the cardiac imaging such as high scanning speed, good temporal resolution and low radiation dose. Objective: To assess the diagnostic accuracy of 128-slice dual source CT cardiac angiography with conventional catheter angiography to find common arteries involved in CAD. Methods: This is a prospective, comparative, cross sectional study conducted at cardiology OPD. Patients with complaint of chest pain and suspected CAD were evaluated by CT and conventional coronary angiography and results were compared. Serum creatinine and ECG status were analyzed before the angiography. SIEMENS 128-slice Dual Source Flash Definition CT Scanner was used as a CT coronary angiography. Severity distribution of coronary artery disease, artery wise distribution of non-significant, significant lesions and coronary artery dominance pattern were analyzed and compared. Results: A total of 70 suspected CAD patients were selected and analyzed. American Heart Association (AHA) model of 17-segment was used to assess the coronary arteries. Normal angiograms reported in 15.71% patients and 58.57% had significant disease. A total of 356 lesions were identified from 690 out of 720 segments. Right coronary artery (RCA) is the most common location of significant lesions which contributes 33.5% (n=55/164). Coronary circulation of right-sided dominance was most commonly reported (70.0%). CT angiography showed 96.13% of an overall sensitivity, 96.28% specificity, 89.72% positive predictive value and 98.49% negative predictive value. Conclusion: 128-slice dual source CT scanner has showed high accuracy and act as non-invasive assessment of coronary arteries in patients with CAD Keywords: Cardiac angiography, Catheter coronary angiography, CT coronary angiography, 128-slice MDCT, Conventional angiography

The myocardial bridge (MB) is a congenital anomaly, in which a segment of a coronary artery courses through the myocardium. The aim of the study was to establish the location of myocardial bridges and the severity of atherosclerotic lesions of the coronary arteries in patients with coronary heart disease symptoms and in individuals who are the potential heart donors for transplantation. The data of the multislice computed tomography coronary angiography of the patients of the Republican Scientific and Practical Centre “Cardiology” from 2016 to 2018 were included in this study. 324 hearts of the deceased donors, which had not been used for orthotopic transplantation, were studied. According to the autopsy and the CT coronary angiography, the myocardial bridges were localized mainly in the left anterior descending artery of the left coronary artery (LCA). In 7.4 % of cases, MBs were found in a distal portion of the intermediate branch of LCA, in the left postero-lateral branch, in the right coronary artery, in the first diagonal artery, as well as along the obtuse marginal artery and the left circumflex coronary artery. In 36 % of cases, the identified bridges were considered as hemodynamically significant with regard to the length of the tunneled artery segment and its depth. Microscopic examination of the tunneled fragments of the coronary arteries in 4.9 % of cases showed the initial signs of damage of the vessel wall in the form of fibromuscular dysplasia and lipidosis. According to the CT coronary angiography results, no causal relationship has been established between the presence of MBs and atherosclerosis in the subepicardial segments of the coronary arteries.
