“…1,[10][11][12][13][14][15][16][17][18] Most of the coronary anomalies remain asymptomatic and are found as an incidental finding with coronary angiography. However, myocardial perfusion can be affected, extending from exertional angina to sudden death, in different subtypes of these anomalies, such as a coronary artery arising from the pulmonary artery and a single coronary artery arising from either the left or right sinus of Valsalva.…”

SUMMARYA 62-year-old man with hypertension and hypercholesterolemia was referred to our unit for evaluation of chest pain. A very rare variant of single coronary artery, in which the anomalous right coronary artery originated as a separate branch from the left anterior descending artery, was incidentally found on his coronary angiography. The anomalous right coronary artery in our case appears to be unique in that it courses intraseptally rather than rightwards proximally and has obstructive atherosclerotic lesions resulting in inferior ischemia. Moreover, the acute angle made by the anomalous right coronary artery to turn toward the atrioventricular groove may have reduced the flow velocity and contributed to the development of inferior ischemia. Anomalous origin of the right coronary artery (RCA) from the left anterior descending coronary artery (LAD) is relatively uncommon and generally of no clinical significance. [2][3][4][5][6][7][8][9] We describe a patient in whom the exertional angina and reversible inferior perfusion defect in technetium-99m radionuclide myocardial perfusion imaging are likely to be the result of an anomalous right coronary artery arising from the left anterior descending artery that differs from those reported previously because of its unique proximal course. CASE REPORTThe patient is a 62-year-old Turkish man with hypertension and hypercholesterolemia as risk factors for coronary heart disease. He had had retrosternal pressure-like chest pain on heavy exertion, relieving with rest, in the previous 6From the

“…If the LMCA is absent, one of the following results may occur: a) the LADA and left Cx arteries, both of normal length and course, may arise from the left sinus of Valsalva separately or with a common ostium ( Fig. 2) (11,12); b) the left Cx artery may arise from the right sinus of Valsalva or the RCA and follow a course posterior to the aorta (13)(14)(15); c) the LADA may arise from the right sinus of Valsalva or the RCA (14-16) injected at 4.5 mL/s followed by 40 mL of saline at 2.5 mL/s. Retrospective ECG-gated reconstructions were generated at 50%, 60%, and 70% of the R-R interval of the ECG cycle.…”

261C oronary artery disease is responsible for millions of deaths per year in developed countries (1, 2). Early recognition of coronary artery disease is important for the prevention of its related complications and improving prognosis (3). Catheter angiography has been considered the gold standard imaging method for evaluating the coronary tree. The major advantages of conventional coronary angiography (CCA) are its high spatial and temporal resolutions and the option of directly performing interventions, such as balloon dilation or coronary stent placement (4). However, CCA is an invasive procedure that carries the risk of morbidity and mortality (3). In addition, CCA provides only luminal data and is limited in revealing changes in the vessel wall and the adjacent soft tissues. Conversely, multidetector computed tomography coronary angiography (MDCT-CA) not only provides visualization of the vessel lumen but also displays the vessel wall and surrounding soft tissues, allowing for the detection of various congenital or acquired abnormalities of the coronary arteries that may not be evident with CCA (3).In this article, on the basis of our experience with more than 15 000 MDCT-CA from seven different centers, we reviewed clinical conditions in which MDCT-CA may be more helpful compared with CCA. Coronary CT techniqueWith the advent of technological refinements in the last decade, MDCT-CA has gained widespread use for the evaluation of coronary artery diseases. Currently, state-of-the-art computed tomography (CT) systems can simultaneously acquire 64 or more submillimeter sections with a gantry rotation time of less than half a second. Previous limitations of CT for evaluating the vascular system, associated with older generation scanners, have now been eliminated. Presently, a thinner section thickness allows for isotropic voxels, which is essential for optimum high-resolution, three-dimensional (3D) reconstruction and other postprocessing displays, such as maximum projection reformatting (MPR) in any selected plane. Faster scanners have resulted in shorter scans and shorter contrast bolus durations, allowing for the use of less contrast agent at a higher flow rate to achieve greater luminal enhancement. Motion artifacts from breathing are no longer a problem since highresolution imaging of the entire heart can be obtained in a single breath hold. Electrocardiography (ECG) gating techniques improve temporal resolution and minimize imaging artifacts caused by cardiac motion. With more recent technological advances, a reduction in radiation dose, for example, by the utilization of prospective gating, has occurred without any deterioration in diagnostic image quality (5).In our centers, images were acquired using either 16-or 64-MDCT scanners. Eighty-five to one hundred milliliters of iodinated contrast medium (Ultravist 370, Schering, Berlin, Germany) was intravenously ABSTRACT In this review, we aimed to outline the clinical and pathological conditions for which multidetector computed tomography coronary angiogr...

Objectives: This study is an effort to bridge the gap regarding the data of prevalence of coronary anomalies in South Asian countries by utilizing coronary computed tomography angiography (CCTA). Methods: This is a cross sectional, descriptive study done at Aga Khan University Hospital Karachi, Pakistan. All adult patients who underwent CCTA from 1-1-2005 to 1-11-2016 were included in the study. Results: Among 897 patients undergoing CCTA, 36 (4.01%) patients were identified as having coronary artery anomalies (CAA). The mean age of patients was 48.3±11.9 years. Male to female ratio was 3:1. Among patients with CAA, the most common indication for CCTA was screening for coronary artery disease (58.3%). 33 patients (3.67%) showed coronary origin and course anomalies, whereas coronary artery fistulas were identified in 3 patients (0.3%). The most common anomaly identified was the anomalous origin of coronary artery from the opposite coronary sinus with anomalous course (1.4%) with anomalous origin of right coronary artery from the left coronary sinus with an inter-arterial course seen in 9 patients. Single coronary artery was seen in three cases (0.3%), in all these cases the single coronary artery originated from the right coronary cusp. In one patient (0.1%) dual left anterior descending (LAD) system was identified. In two cases (0.2%) fistulous connection of LAD with pulmonary artery was seen, while fistula from LAD to coronary sinus was identified in one patient. Conclusions: This study highlights the fact that the prevalence of coronary anomalies on CCTA in this region is similar to the data reported from the rest of the world. JRCD 2017; 3 (4): 116-121
