Diagnostic accuracy of computed tomography angiography in patients after bypass grafting: comparison with invasive coronary angiography.
OBJECTIVES We sought to evaluate the contribution of noninvasive dual-source computed tomography angiography (CTA) in the comprehensive assessment of symptomatic patients after coronary artery bypass grafting (CABG). BACKGROUND Assessment of bypass grafts and distal runoffs by invasive coronary angiography is cumbersome and often requires extra procedure time, contrast load, and radiation exp...
متن کاملDiagnostic accuracy of multidetector computed tomography coronary angiography in patients with angiographically proven coronary artery disease.
OBJECTIVES The aim of the present study was to evaluate the diagnostic accuracy in detecting high-grade coronary stenoses in patients with known coronary artery disease (CAD) using multidetector computed tomography (MDCT). BACKGROUND The MDCT systems with electrocardiographic (ECG)-gating permit visualization of the coronary arteries. However, severe calcifications and higher heart rates are ...
متن کاملDiagnostic accuracy of coronary angiography using 64-slice computed tomography in coronary artery disease
OBJECTIVES To conduct a meta-analysis and investigate the diagnostic value of 64-slice computed tomography (CT) angiography for diagnosing coronary artery disease (CAD) in patients. METHODS A comprehensive literature search from March 2005 to August 2014 was performed on the following databases: Cochrane Library; Medline; EmBase; PubMed; and BioMed Central database. As a reference standard, s...
متن کاملComputed tomography coronary angiography.
Recent developments in computed tomography technology have made imaging of the coronary arteries possible. All the same, the rapid motion and small dimensions of the coronary vessels make coronary computed tomography angiography (coronary CTA) challenging. With the last generations of 16- and 64-slice computed tomography and adequate patient preparation (which includes lowering of the heart rat...
متن کاملCoronary Computed Tomography Angiography
Coronary computed tomographic angiography (cCTA) as a noninvasive approach underlies a rapid technological development with an impressive improvement of spatial and temporal resolution of the images. Therefore, it has become an accurate and costeffective method to detect or exclude obstructive coronary artery disease (CAD) in patients with low to medium cardiovascular risk profile, as recommend...
