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(More)
BACKGROUND We conducted a prospective longitudinal study to investigate the yet unknown clinical significance of myocardial fibrosis in patients with non-ischemic cardiomyopathy without history of congestive heart failure (CHF). METHODS AND RESULTS At 3 tertiary referral centers, 228 patients with non-ischemic cardiomyopathy without history of CHF were(More)
OBJECTIVES The aim of this study was to assess the long-term prognostic role of multidetector computed tomography coronary angiography (CTA) in patients with suspected coronary artery disease (CAD). BACKGROUND Use of CTA is increasing in patients with suspected CAD. Although there is a large body of data supporting the prognostic role of CTA for major(More)
AIMS In symptomatic patients with suspected coronary artery disease (CAD), computed tomographic angiography (CTA) improves patient selection for invasive coronary angiography (ICA) compared with functional testing. The impact of measuring fractional flow reserve by CTA (FFRCT) is unknown. METHODS AND RESULTS At 11 sites, 584 patients with new onset chest(More)
Noninvasive assessment of coronary in-stent restenosis (ISR) is clinically useful but 4- and 16-slice multidetector computed tomography is limited due to stent strut artifacts. We evaluated the feasibility and accuracy of 64-slice multidetector computed tomography in the diagnosis of ISR to validate its accuracy in ISR quantification and identify factors(More)
The accuracy of computed tomography (CT) for assessment of coronary stents is as yet unproven and radiation exposure has been a concern. The aim of our study is to compare radiation dose and diagnostic performance of CT with prospective ECG-triggering versus retrospective ECG-triggering for the detection of in-stent restenosis (ISR). We enrolled 168(More)
BACKGROUND The aim of this study was to assess the accuracy of a comprehensive multidetector computed tomography (MDCT) evaluation of the aortic annulus (AoA), coronary artery disease (CAD), and peripheral vessels in patients referred for transcatheter aortic valve implantation (TAVI). METHODS In 60 patients referred for TAVI, the following parameters(More)
BACKGROUND Multidetector computed tomography (MDCT) provides detailed assessment of valve annulus and iliofemoral vessels in transcatheter aortic valve replacement (TAVR) patients. However, data on diagnostic performance of MDCT coronary angiography (MDCT-CA) are scarce. The aim of the study is to assess diagnostic performance of MDCT for coronary artery(More)
AIMS Previous studies have shown that prodromal angina (PA) occurs frequently in acute myocardial infarction (MI) patients. However, the potential benefits of PA on ischaemic myocardial damage remain unknown. METHODS AND RESULTS One-hundred and fifty-four patients with acute ST-segment elevation MI successfully treated with primary percutaneous coronary(More)
AIM To compare the feasibility, accuracy, and effective radiation dose (ED) of multidetector computed tomography (MDCT) in the detection of coronary artery disease using a combined ED-saving strategy including prospective electrocardiogram (ECG) triggering with a short x-ray window and a body mass index (BMI)-adapted imaging protocol using adaptive(More)
