Low-dose computed tomography coronary angiography with prospective triggering: a promise for the future.
omputed tomography for coronary angiography (CTCA) as rapidly evolved into a valuable alternative to invasive oronary angiography for accurate noninvasive assessment f coronary morphology. Although increasing values of ositive predictive values are continuously reported, it is enerally accepted that the strength of this technology at resent lies in its excellent ability to exclude coronary arte...
متن کاملAccuracy of low-dose computed tomography coronary angiography using prospective electrocardiogram-triggering: first clinical experience.
AIMS To evaluate the accuracy of low-dose computed tomography coronary angiography (CTCA) using prospective ECG-triggering for the assessment of coronary artery disease (CAD). METHODS AND RESULTS A total of 30 patients (19 males, 11 females, mean age 58.8 +/- 9.9 years) underwent low-dose CTCA and invasive coronary angiography (CA) [median 2 days (0, 41)]. Before CT scanning, intravenous beta...
متن کاملPrognostic performance of low-dose coronary CT angiography with prospective ECG triggering.
OBJECTIVE To assess the prognostic value of low-dose 64-slice coronary CT angiography (CCTA) using prospective ECG triggering in a patient population with known or suspected coronary artery disease (CAD). DESIGN Longitudinal follow-up study. SETTING Tertiary referral cardiac imaging centre. PATIENTS 434 consecutive patients who were referred for evaluation of CAD by CCTA. METHODS The pr...
متن کاملDiagnostic accuracy of coronary computed tomography angiography: a comparison between prospective and retrospective electrocardiogram triggering.
OBJECTIVES The aim of this study was to compare the diagnostic performance of multidetector computed tomography (MDCT) with prospective electrocardiogram (ECG) triggering versus retrospective ECG triggering. BACKGROUND MDCT allows the noninvasive visualization of the coronary arteries. However, radiation exposure is a reason for concern. METHODS One hundred eighty consecutive patients sched...
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...
