Coronary CT angiography—future directions

Cardiovascular Diagnosis and Therapy, 2017
Clinical applications of coronary CT angiography (CTA) will typically be based on the method´s very high sensitivity to identify coronary stenosis if image quality is good and if the pre-test likelihood of the patients is in the lower range. Guidelines of national and international cardiac societies are starting to incorporate coronary CTA into their ...

Radiation dose estimates in dual-source computed tomography coronary angiography [PDF]

, 2018
The purpose of this study was to quantify radiation dose parameters of dual-source CT coronary angiography. Eighty patients underwent contrast-enhanced, retrospectively ECG-gated dual-source CT coronary angiography with heart rate-adapted ECG pulsing ...

Comparison of coronary CT angiography and invasive coronary angiography results

Irish Journal of Medical Science (1971 -)
Abstract Introduction Coronary artery disease (CAD) is a leading cause of death worldwide. Accurate diagnosis and management are critical. Non-invasive imaging, such as coronary computed tomography angiography (CCTA), is vital for early diagnosis and treatment planning.

Coronary CT Angiography in Takayasu Arteritis

JACC: Cardiovascular Imaging, 2011
The aim of this study was to use coronary computed tomographic (CT) angiography to characterize coronary artery involvement in patients with known Takayasu arteritis who present with anginal chest pain or shortness of breath.Takayasu arteritis is a primary vasculitis of the large vessels, which mainly affects the aorta and its branches but can also ...

Contrast‐enhanced CT—Nephrotoxic or not? A critical review of propensity‐score‐adjusted studies

Journal of Internal Medicine, EarlyView.
Abstract Retrospective, propensity‐score‐adjusted (PSA) studies have indicated to practitioners in the field that contrast‐induced acute kidney injury (AKI) after contrast‐enhanced CT (CECT) is of minor importance or even non‐existent. This has led to controversies between clinicians demanding CECT not to miss any diagnoses and radiologists reluctant ...

Carotid artery dissection linked to intermittent apnoeic swimming: A case–control study

Experimental Physiology, EarlyView.
Abstract Internal carotid artery (ICA) dissection is a rare and potentially devastating cause of cerebral ischaemia, initiated by an intimal tear or rupture of the vasa vasorum, that can lead to an intraluminal thrombus, vascular stenosis, occlusion, or dissecting aneurysm formation.

Takotsubo cardiomyopathy and sepsis: a systematic review [PDF]

, 2017
Takotsubo cardiomyopathy (TTC) is characterized by a systolic dysfunction localized in the apical and medial aspect of the left ventricle. It is usually related to physical or emotional stress.

The influence of delayed ventricular activation on cardiac repolarization: Insights from electrocardiographic imaging

The Journal of Physiology, EarlyView.
Abstract figure legend This study examines the relationships between activation and repolarization times in epicardial reconstructed unipolar electrograms derived from ECG‐imaging in patients with normal and delayed ventricular activation. In patients with a narrow QRS‐complex, ECG‐imaging reveals significant variability in the activation ...

Effect of Vascepa (icosapent ethyl) on progression of coronary atherosclerosis in patients with elevated triglycerides (200-499 mg/dL) on statin therapy: Rationale and design of the EVAPORATE study. [PDF]

, 2018
Despite reducing progression and promoting regression of coronary atherosclerosis, statin therapy does not fully address residual cardiovascular (CV) risk.
