BACKGROUND: Aim of this study was to assess the accuracy of ventricular septal defects (VSD) using high pitch computed tomography angiography (CTA) of the chest in children below 1 year of age, compared to the intraoperative findings and echocardiography. METHODS: Out of 154 patients that underwent Dual-Source CTA of the chest using a high-pitch protocol at low tube voltages (70-80 kV), 55 underwent surgical repair of a VSD (median age 8 days, range 1-348 days)...

BACKGROUND: Myocardial CT perfusion imaging with dual energy (DE-CTP) can produce myocardial iodine perfusion maps. This study evaluated the accuracy of first pass myocardial iodine concentration in DE-CTP compared to CT derived dynamic myocardial blood flow (MBF) to determine regional myocardial ischemia in an animal model of coronary stenosis using invasive Fractional Flow Reserve (FFR). METHODS: Seven anaesthetised pigs (mean weight 51 ± 4 kg) had a graded coronary artery stenosis produced in six vessels (plus one control animal) using a methacrylate plug with FFR recorded in the target artery (ischemia = FFR<0...

INTRODUCTION: Non-statin therapy (NST) is used as second-line treatment when statin monotherapy is inadequate or poorly tolerated. OBJECTIVE: To determine the association of NST with plaque composition, alone or in combination with statins, in patients undergoing coronary computed tomography angiography (coronary CTA). METHODS: From the multicenter CONFIRM registry, we analyzed individuals who underwent coronary CTA with known lipid-lowering therapy status and without prior coronary artery disease at baseline...

BACKGROUND: Infected coronary artery aneurysms (ICAA) represent a rare but potentially fatal complication of pre-existent atherosclerotic or non-atherosclerotic coronary artery disease, percutaneous coronary artery intervention, endocarditis or extracardiac infection. METHODS: A retrospective analysis of four cases in addition to 51 infected coronary artery aneurysms from the literature, for a total of 55 ICAA was performed. Clinical and morphological information including age, sex, clinical presentation, microbial cultures, size, location and associated abnormalities as well as patient outcome was reviewed...

BACKGROUND: To investigate whether aortic valve calcification (AVC) scoring performed with different workstation platforms generates comparable and thus software-independent results. METHODS: In this IRB-approved retrospective study, we included 100 consecutive patients with symptomatic aortic stenosis undergoing CT prior to transcatheter aortic valve implantation. Two independent observers performed AVC scoring on non-enhanced images with commercially available software platforms of four vendors (GE, Philips, Siemens, 3mensio)...

BACKGROUND: The association of plaque morphology with ischemia in non-obstructive lesions has not been fully eludicated: Calcium density and high-risk plaque features have not been explored. OBJECTIVES: to assess whether high-risk plaque or calcified, and global mixed including non-calcified plaque burden (G-score) by coronary CTA predict ischemia in non-obstructive lesions using non-invasive fractional flow reserve (FFRCT ). METHODS: In 106 patients with low-to-intermediate pre-test probability referred to coronary 128-slice dual source CTA, lesion-based and distal FFRCT were computated...

OBJECTIVES: To assess evaluability and diagnostic accuracy of a low dose CT angiography (CTA) protocol for carotid arteries using latest Iterative Reconstruction (IR) algorithm in comparison with standard 100 kVp protocol using previous generation CT and IR. MATERIALS AND METHODS: 105 patients, referred for CTA of the carotid arteries were prospectively enrolled in our study and underwent CTA with 80 kVp and latest IR algorithm (group 1). Data were retrospectively compared with 100 consecutive patients with similar examination indications that had previously undergone CTA of carotid arteries with a standard 100 kVp protocol and a first generation IR algorithm (group 2)...

AIMS: Pulmonary vein isolation (PVI) using cryoballoon has been accepted as a safe and effective method for treatment of atrial fibrillation (AF). Despite advances in catheter-based technologies, some patients still experience AF recurrence. In this study, we aimed to compare left atrial appendage (LAA) morphology in AF patients and subjects with sinus rhythm and also investigate the association between LAA morphology and success of PVI using cryoballoon in subjects with AF. METHODS: In this prospective study, 359 AF patients who underwent pre-ablation computed tomographic angiography (CTA) scan between January 2013-March 2016 were included as the patient group...

Search Tips

Use Boolean operators: AND/OR

diabetic AND foot
diabetes OR diabetic

Exclude a word using the 'minus' sign

Virchow -triad

Use Parentheses

water AND (cup OR glass)

Add an asterisk (*) at end of a word to include word stems
