AIMS Exercise stress testing is often used as the initial non-invasive diagnostic test in symptomatic patients with suspected obstructive coronary artery disease. Positive standard ECG criteria are quite specific for obstructive coronary artery disease, but there may be a substantial number of false negative tests, including patients with severe coronary artery disease. Also, exercise stress te...

We report the case of a 51-year-old male with pectus excavatum (PEX) who presented stress-related chest pain as symptom acute non-ST elevation myocardial infarction. Coronary angiography (CAG) revealed suspected single coronary artery (SCA) anatomy diffuse atherosclerotic narrowing, without evidence other ostia in aortic root. The diagnosis was confirmed on cardiac computed tomography (CCTA) SC...

Iatrogenic type A dissection caused by percutaneous coronary intervention is a rare but life-threatening condition. Computed tomographic angiography is an excellent diagnostic tool commonly utilized if such procedural complication is clinically suspected. There are, however, potential diagnostic challenges. Herein, we present an illustrative case of iatrogenic type A dissection successfully dia...

This study was conducted on a human anthropomorphic phantom to investigate the effective dose and entrance skin dose (ESD) in selected radiosensitive organs through invasive and computed tomography (CT) coronary angiography procedures using different dose-saving techniques. The effective dose was calculated as 2.49, 3.35 and 9.62 mSv, respectively, corresponding to three coronary CT angiography...

The introduction of multislice computed tomography angiography (MSCT) has provided new information for percutaneous coronary intervention (PCI), especially in complex lesions. It provides valuable adjustments about coronary lesions, which are predictors of procedural success, for example, in chronic total occlusions, in bifurcations and recently in aorto-ostial lesion PCI. In multiple fields, t...

BACKGROUND Cardiac allograft rejection and vasculopathy are the main factors limiting long-term survival after heart transplantation.In this pilot study we investigated whether non-invasive methods are beneficial to detect cardiac allograft rejection (Grade 03 R) and cardiac allograft vasculopathy. Thus we compared multi-slice computed tomography and magnetic resonance imaging with invasive met...

Coronary CT angiography versus standard emergency department evaluation for acute chest pain and diabetic patients: Is there benefit with early coronary CT angiography? Results of the randomized comparative effectiveness ROMICAT II trialCoronary CT angiography versus standard emergency department evaluation for acute chest pain and diabetic patients: Is there benefit with early coronary CT angi...

BACKGROUND Epicardial fat may play a role in the pathogenesis of coronary artery disease (CAD). We explored the relationship of epicardial fat volume (EFV) with the presence and severity of CAD or myocardial perfusion abnormalities in a diverse, symptomatic patient population. METHODS AND RESULTS Patients (n=380) with known or suspected CAD who underwent 320-detector row computed tomographic ...

Validation of a new contrast material protocol adapted to body surface area for optimized low-dose CT coronary angiography with prospective ECG-triggering. Int J Cardiovasc Imaging 2010;26:591–7. 13. Tatsugami F, Husmann L, Herzog BA, Burkhard N, Valenta I, Gaemperli O et al. Evaluation of a body mass index-adapted protocol for low-dose 64-MDCT coronary angiography with prospective ECG triggeri...
