Monoenergetic extrapolation of cardiac dual energy CT for artifact reduction.
Acta Radiol
April 2015
Department of Radiology and Radiological Science, Medical University of South Carolina, Charleston, SC, USA.
Background: Monoenergetic extrapolation of cardiac dual-energy computed tomography (DECT) could be useful in artifact reduction in clinical practice.
Purpose: To evaluate the potential of monoenergetic extrapolation of cardiac DECT data for reducing artifacts from metal and high iodine contrast concentration.
Material And Methods: With IRB approval and in HIPAA compliance, 35 patients (22 men, 61 ± 12 years) underwent cardiac DECT with dual-source CT (100 kVp and 140 kVp).
Comparison of the first and second cryoballoon: high-volume single-center safety and efficacy analysis.

Department of Cardiology and Internal Intensive Care Medicine, Heart Center Munich-Bogenhausen, Munich Municipal Hospital Group, Munich, Germany.
Background: Cryoballoon (CB) ablation results in >70% freedom from atrial fibrillation at 1 year. Single-center data of the first (CBG1) and second (CBG2) cryoballoon, recently introduced, were analyzed to compare safety and efficacy.
Methods And Results: From March 2011 to December 2012, CB ablation with spiral mapping was performed consecutively in 484 patients with symptomatic atrial fibrillation.

Purpose: To investigate in vitro and in vivo the use of image-based and raw data-based iterative reconstruction algorithms for quantification of coronary artery calcium by using the Agatston score and subsequent cardiac risk stratification.
Materials And Methods: In vitro data were obtained by using a moving anthropomorphic cardiac phantom containing calcium inserts of different concentrations and sizes. With institutional review board approval and HIPAA compliance, coronary calcium imaging data of 110 consecutive patients (mean age ± standard deviation, 58.
Comparison of the effect of iterative reconstruction versus filtered back projection on cardiac CT postprocessing.

Heart and Vascular Center, Medical University of South Carolina, Ashley River Tower, 25 Courtenay Drive, Charleston, SC, 29425-2260; Department of Cardiology and Intensive Care Medicine, Heart Center Munich-Bogenhausen, Munich, Germany.
Rationale And Objectives: To investigate the impact of iterative reconstruction in image space (IRIS) on image noise, image quality (IQ), and postprocessing at coronary computed tomography angiography (cCTA) compared to traditional filtered back-projection (FBP).
Materials And Methods: The cCTA results of 50 patients (26 men; 58 ± 15 years, body mass index 31.5 ± 6.
Comparison of epicardial fat volume by computed tomography in black versus white patients with acute chest pain.

Disparities in the risk of coronary artery disease (CAD) between races may be influenced by differences in the thoracic adipose tissue. We compared computed tomography (CT)-derived volumes of epicardial adipose tissue (EAT), mediastinal adipose tissue (MAT), and pericoronary fat thickness (PFT) and correlations with CAD between black and white patients. This institutional review board-approved Health Insurance Portability and Accountability Act-compliant study included 372 age- and gender-matched black versus white patients (186 black, 54 ± 11 years, 50% men; 186 white, 54 ± 11 years, 50% men) who underwent CT for chest pain evaluation.

Aims: Prospective data on the usage of 3-dimensional imaging based annulus sizing on the outcome of TAVI is not available yet and there is general uncertainty about the optimal degree of oversizing. In the current study we therefore assessed a 3-D MSCT guided over-sizing approach and evaluated the clinical outcome of different degrees of oversizing.
Methods: TAVI-size-selection was done using systolic MSCT-annulus cross-sectional-area (CSA) measurements in 107 patients with severe aortic stenosis with the goal to oversize the 3rd generation balloon expandable Edwards Sapien XT (ESTV) device in relation to the native aortic annulus CSA.

Article Synopsis
- The cryoballoon technique is a new way to treat a heart condition called atrial fibrillation and is different from an older method called radiofrequency ablation.
- Researchers wanted to see if they could monitor heart signals in real-time while using the cryoballoon technique by adding a special mapping tool inside the balloon.
- In their study with 141 patients, they found that they could successfully monitor the heart signals during treatment in about 41% of cases and learned that if they achieved isolation in 83 seconds, it meant better chances of long-term success.

Background: Atrial fibrillation is the most common sustained arrhythmia observed worldwide. Despite modern ablative treatment options, pharmacotherapy remains the first-line therapy in patients with atrial fibrillation.
Objective: Based on recently published guidelines for the management of atrial fibrillation, the present paper reviews the current and emerging concepts of pharmacotherapy in atrial fibrillation.
