Autor: Naser Ahmadi, David Z. Chow, Tony DeFrance, Dan Gebow, Matthew J. Budoff, Brian J Hsieh, Ferdinand Flores, Sandy T. Liu

Publikováno v: Atherosclerosis. 237:494-498

Background : Previous studies have shown that computed tomography coronary angiography (CTA) in patients with suspected coronary artery disease (CAD) predicts short term adverse events. However, there is no current data on whether identifying atheros

Computed tomography stress myocardial perfusion imaging in patients considered for revascularization: a comparison with fractional flow reserve

Autor: Paul Antonis, John Troupis, Michael Leung, Ian T Meredith, Sujith Seneviratne, Tony DeFrance, Sarah A. Hope, Brian Ko, Sam J. Lehman, Arthur Nasis, Marcus Crossett, James D. Cameron

Publikováno v: European Heart Journal. 33:67-77

Aims Adenosine stress computed tomography myocardial perfusion imaging (CTP) is an emerging non-invasive method for detecting myocardial ischaemia. Its value when compared with fractional flow reserve (FFR), a highly accurate index of ischaemia, is u

Advances in Contrast-Enhanced Cardiovascular CT for the Evaluation of Myocardial Perfusion

Autor: Sujith Seneviratne, Tony DeFrance, Arthur Nasis

Publikováno v: Current Cardiovascular Imaging Reports. 3:372-381

Multidetector CT (MDCT) angiography is a robust method for the accurate diagnosis of coronary artery disease (CAD) in selected patient populations. Recent advances in CT technology have broadened the application of MDCT as a stand-alone imaging modal

Autor: Markus Stühlinger, Otmar Pachinger, Dieter zur Nedden, Wolfgang Dichtl, Thomas Berger, Karin Spuller, Gudrun Feuchtner, Daniel Junker, Andrea Klauser, Florian Hintringer, Tony DeFrance

Publikováno v: European Journal of Radiology. 68:456-464

Purpose: To assess whether fusion of multislice computed tomography (CT) images with electroanatomical (EA)-mapping data using a new image integration module (CartoMerge TM ) is feasible and accurate to navigate ablation catheters in right and left a

Temporary arterial stenting: Comparison to permanent stenting and conventional balloon injury in a rabbit carotid artery model

Autor: Frank Litvack, Neal L. Eigler, Tony DeFrance, Masato Nakamura, Eldad Rechavia, Asish Parikh, Michael C. Fishbien

Publikováno v: Catheterization and Cardiovascular Diagnosis. 41:85-92

The objective was to assess the arterial wall response to temporary stenting with a removable nitinol stent in comparison with permanent stenting and balloon injury at 28 days in the rabbit carotid artery. Restenosis remains an important limiting fac
