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 کاملCan coronary computed tomography angiography replace invasive angiography? Coronary computed tomography angiography cannot replace invasive angiography.
O ne million patients undergo invasive coronary angiogra-phy (CA) in the United States every year. 1 In view of its invasive nature and related costs, noninvasive imaging of coronary imaging has the theoretical appeal to improve comfort for patients, reduce cost, and refine patient selection to limit invasive procedures to patients requiring treatment for ischemic coronary artery disease (CAD)....
متن کاملAdenosine triphosphate stress dual-source computed tomography to identify myocardial ischemia: comparison with invasive coronary angiography
PURPOSE The purpose of this study was to investigate the utility incremental diagnostic value of combined assessment with coronary CT angiography (CCTA) and myocardial CT perfusion imaging (CTP) using dual-energy technology with an Adenosine Triphosphate (ATP) load technique. MATERIALS AND METHODS Twenty-one patients underwent ATP-provocation dual-energy CT and CAG. We compared the diagnostic...
متن کامل[Non-invasive assessment of coronary artery bypass grafts by computed tomography: comparison with conventional coronary angiography].
INTRODUCTION AND OBJECTIVES Although it has been demonstrated that the diagnostic accuracy of computed tomography in the non-invasive assessment of major epicardial coronary arteries is high, only a few studies have evaluated the technique's reliability in assessing coronary artery bypass grafts. The aim of this study was to determine the diagnostic accuracy of multidetector computed tomography...
متن کاملDual source computed tomography coronary angiography in new onset cardiomyopathy.
AIM To evaluate safety and utility of coronary computed tomography angiography (CCTA) compared to invasive coronary angiography (ICA) in new cardiomyopathy. METHODS Eighteen patients (mean age 56.5 years, 10 males) who presented for evaluation of new onset heart failure with evidence of systolic dysfunction (ejection fraction < 40%) on echocardiography and recent ICA were prospectively enroll...
