Combined cardiac congenital anomalies assessed by multi-slice spiral computed tomography

Accuracy of 16-Row Multidetector Computed Tomography for the Assessment of Coronary Artery Stenosis

“…The number of nonevaluable segments also may decrease with the use of newer generation scanners. [23][24][25][26] New generation 64-slice MDCT systems permit the acquisition of cardiac studies in less than 10 seconds, allowing faster contrast injection rates and having lower contrast volume requirements, and reducing the number of artifacts related to inadequate breath holding and heart rate variability. One report suggests that the performance characteristics of 64-slice MDCT in terms of spatial and temporal resolution lead to measurable improvements in image quality.…”

“…One report suggests that the performance characteristics of 64-slice MDCT in terms of spatial and temporal resolution lead to measurable improvements in image quality. 26 Detector width in 64-slice CT scanners results in lower resolution than fluoroscopy. It is unlikely that MDCT will reach the spatial and temporal resolution of fluoroscopic angiography in the foreseeable future; moreover, the technology required to achieve this would likely result in increasing radiation exposure to the patient.…”

Association of aortic coarctation and malignant right coronary artery anomaly: an unusual cause of angina pectoris

“…Reduced blood flow through a compressed artery can result in myocardial ischemia and its clinical manifestations, which range from typical angina to malignant and fatal arrhythmias, sometimes followed by sudden death 7. The association of coronary anomalies with aortic coarctation is a very rare finding and both left8 and right9 coronary anomalies have been described in association with this great vessel malformation. Anatomopathological studies suggest that in individuals who present cardiac ischemia as a result of the anomalous course of the right coronary artery (arising from the contralateral sinus), restriction of blood flow occurs in rare and isolated episodes.…”

Mutil-slice computed tomography in coronary artery disease

“…MDCT coronary angiography is very useful in assessing the origin and course of congenitally anomalous coronary arteries [38,39,40] Compared to conventional angiography, MDCT can easily determine the 3-dimensional relationship of anomalous coronary arteries with the aorta and pulmonary arterial trunk. In addition, MDCT can also detect arteriovenous fistulae, myocardial bridges and aneurismal dilatation of the coronary vessels.…”
