Left ventricular fibro-fatty replacement in arrhythmogenic right ventricular dysplasia/cardiomyopathy: prevalence, patterns, and association with arrhythmias.

Background: Left ventricular (LV) fibrofatty infiltration in arrhythmogenic right ventricular (RV) dysplasia/cardiomyopathy (ARVD/C) has been reported, however, detailed cardiovascular magnetic resonance (CMR) characteristics and association with outcomes are uncertain. We aim to describe LV findings on CMR in ARVD/C patients and their relationship with arrhythmic outcomes.

Methods: CMR of 73 subjects with ARVD/C according to the 2010 Task Force Criteria (TFC) were analyzed for LV involvement, defined as ≥ 1 of the following features: LV wall motion abnormality, LV late gadolinium enhancement (LGE), LV fat infiltration, or LV ejection fraction (LVEF) < 50%.

Fibrotic Lung Disease at CT Predicts Adverse Outcomes in Patients Undergoing Transcatheter Aortic Valve Replacement.

Purpose: To evaluate the relationship between CT findings of diffuse lung disease and post-transcatheter aortic valve replacement (TAVR) outcomes.

Materials And Methods: Retrospective review of pre-TAVR CT scans obtained during 2012-2017 was conducted. Emphysema, reticulation, and honeycombing were separately scored using a five-point scale and applied to 10 images per examination.

High-pitch non-gated scans on the second and third generation dual-source CT scanners: comparison of coronary image quality.

Objective: To examine differences in image quality of the coronary arteries when performing high-pitch non-electrocardiography (ECG)-gated scans on the second-generation (2G) and third-generation (3G) dual-source CT scanners.

Methods: We retrospectively examined patients with high-pitch non-ECG-gated CT angiography (CTA) of the chest or chest/abdomen/pelvis. Outpatient scans from 59 patients in the 3G high-pitch group and 53 patients in the 2G high-pitch group were included.

Pulmonary venous anomalies causing misdiagnosis of pulmonary arteriovenous malformations.

Purpose: To investigate pulmonary venous anomaly as a cause of pulmonary arteriovenous malformation (PAVM) misdiagnosis.

Materials And Methods: We reviewed adult patients within a 7.5-year period with CT scans initially diagnosed with PAVM and subsequent conventional pulmonary angiograms.

Evaluation of Coronary Artery Disease and Coronary Anomalies with a Handheld Smartphone.

The purpose of this study was to determine the diagnostic accuracy of an iPhone for evaluation of the coronary arteries on coronary CT angiography (CTA) in comparison to a standard clinical workstation. Fifty coronary CTA exams were selected to include a range of normal and abnormal cases including both coronary artery disease (CAD) of varying severity and coronary artery anomalies. Two cardiac radiologists reviewed each exam on a standard clinical workstation initially and then on an iPhone 6 after a washout period.

Role of multidetector CT in assessment of repaired tetralogy of Fallot.

The population of adults with repaired tetralogy of Fallot (TOF) is growing, thanks to improvements in the surgical and medical management of this condition. Accordingly, late postrepair complications are important medical concerns in these individuals. Initial surgical repair of TOF typically occurs in infancy, consisting of patch repair of the ventricular septal defect (VSD) and relief of right ventricular outflow tract (RVOT) obstruction.
