Coronary computed tomography angiography (CCTA) allows three-dimensional visualisation of the origin, course and ending coronary vessels with high spatial resolution, yielding an accurate depiction artery anomalies (CAAs). This study sought to determine prevalence, incidence characteristics CAAs detected CCTA in a single centre Switzerland.CAAs were retrospectively identified 5 634 consecutive patients referred for between March 2007 July 2015. Single arteries, Bland-White-Garland syndrome,...
Abstract Aims Anomalous origin of a coronary artery from the opposite sinus (ACAOS) has been associated with adverse cardiac events in young. It remains unknown whether this holds true for middle-aged patients uncorrected ACAOS as well. We assessed outcome newly diagnosed by computed tomography angiography (CCTA) compared matched cohort. Methods and results retrospectively identified 68 consecutive documented CCTA. course anomalous vessel between aorta pulmonary were classified interarterial...
The clinical utility of a latest generation iterative reconstruction algorithm (adaptive statistical [ASiR-V]) has yet to be elucidated for coronary computed tomography angiography (CCTA). This study evaluates the impact ASiR-V on signal, noise and image quality in CCTA.Sixty-five patients underwent clinically indicated CCTA 256-slice CT scanner using an ultralow-dose protocol. Data sets from each patient were reconstructed at 6 different levels ASiR-V. Signal intensity was measured by...
AimsSingle-source, dual-energy coronary computed tomography angiography (CCTA) with monochromatic image reconstruction allows significant noise reduction. The aim of the study was to evaluate impact CCTA on stent imaging, as latter is known be affected by artefacts from highly attenuating strut material resulting in artificial luminal narrowing.
In adults with congenital heart disease and systemic right ventricles, progressive ventricular systolic dysfunction is common associated adverse outcomes. Our aim was to assess the impact of phosphodiesterase-5-inhibitor tadalafil on function.This a double-blind, randomized, placebo-controlled, multicentre superiority trial (NCT03049540) involving 100 ventricles (33 women, mean age: 40.7 ± 10.7 years), comparing 20 mg once daily versus placebo (1:1 ratio). The primary endpoint change in...
Rationale Patients with chronic obstructive pulmonary disease (COPD) suffer from significantly more cardiovascular comorbidity and mortality than would be anticipated conventional risk factors. The aim of this study was to determine whether COPD patients have a higher coronary artery calcium score (CACS) epicardial fat burden, compared control subjects, their association events. Methods From registry 1906 81 clinically diagnosed were one-to-one matched non-COPD subjects smoking history,...
Iterative reconstruction (IR) algorithms allow for a significant reduction in radiation dose of coronary computed tomography angiography (CCTA). We performed head-to-head comparison adaptive statistical IR (ASiR) and model-based (MBIR) to assess their impact on quantitative image parameters diagnostic accuracy submillisievert CCTA.CCTA datasets 91 patients were reconstructed using filtered back projection (FBP), increasing contributions ASiR (20, 40, 60, 80, 100%), MBIR. Signal noise...
To provide data on the value of fused cardiac hybrid imaging with coronary computed tomography angiography (CCTA) and positron emission myocardial perfusion (PET-MPI) in patients complex artery anomalies (CCAA).This is a retrospective, single-center study.Seven consecutive CCAA (mean 57 ± 7 y, 86% were male) who underwent clinically indicated CCTA/PET-MPI between 2005 2015 our clinic included. The findings from both modalities evaluated these patients.Out seven CCAA, two had...
To compare the predictive value of epicardial and intrathoracic fat volume (EFV, IFV), coronary artery calcium (CAC) score, single-photon emission computed tomography (SPECT) myocardial perfusion imaging (MPI) for major adverse cardiac events (MACE). Follow-up was obtained in 275 patients with known or suspected disease (CAD), who underwent SPECT-MPI including non-contrast (CT) attenuation correction to evaluate ischaemic heart whom EFV, IFV, CAC score were calculated from CT. Associations...
