OBJECTIVES In acute type A dissection (AAAD), it is commonly decided to carry out immediate surgical repair without invasive diagnostics. The hybrid operating room (Hybrid OR) concept encompasses simultaneous haemodynamic control, non-invasive and invasive diagnostics and immediate surgical and/or interventional treatment. Results over a seven-year period are presented here. METHODS From Marc...
BACKGROUND- Obstructive coronary artery disease diagnosis in symptomatic patients often involves noninvasive testing before invasive coronary angiography. A blood-based gene expression score (GES) was previously validated in nondiabetic patients referred for invasive coronary angiography but not in symptomatic patients referred for myocardial perfusion imaging (MPI). METHODS AND RESULTS- This p...
Cardiovascular specialists should be aware of the common types of congenital vascular anomalies and understand their implications for the patient's treatment and the likelihood of associated morbidity. Conventional angiography, the gold standard in vascular imaging, is an invasive and expensive method. Therefore, in recent years, less invasive techniques such as computed tomography angiography ...
OBJECTIVES To evaluate the diagnostic and prognostic benefits of CT coronary angiography (CTCA) using the 2016 National Institute for Health and Care Excellence (NICE) guidelines for the assessment of suspected stable angina. METHODS Post hoc analysis of the Scottish COmputed Tomography of the HEART (SCOT-HEART) trial of 4146 participants with suspected angina randomised to CTCA. Patients wer...
The portal venous system must be evaluated before planning the treatment of patients with portal hypertension, portal vein thrombosis, hepatic veins occlusion or a tumour of the liver, pancreas, or bile duct. Colour Doppler ultrasonography (US), catheter angiography, computed tomographic angiography (CTA) and magnetic resonance angiography (MRA) can be used for portal venous system imaging. Col...
Novel developments in MR angiography are reviewed that enable non-invasive clinical imaging of normal and abnormal vessels of the spinal cord. Current fast contrast-enhanced MR techniques are able 1) to visualize vessels supplying or draining the spinal cord and 2) to differentiate spinal cord arteries from veins. The localization of the Adamkiewicz artery, the largest artery supplying the thor...
OBJECTIVE To evaluate differences in downstream testing, coronary revascularisation, and clinical outcomes following non-invasive diagnostic modalities used to detect coronary artery disease. DESIGN Systematic review and network meta-analysis. DATA SOURCES Medline, Medline in process, Embase, Cochrane Library for clinical trials, PubMed, Web of Science, SCOPUS, WHO International Clinical Tr...
AIMS To assess whether a strategy of invasive management without stents in selected acute coronary syndrome (ACS) patients with a large thrombus burden (LTB) might be feasible and safe. METHODS AND RESULTS We performed a prospective non-randomised observational cohort study of invasive treatment decisions guided by optical coherence tomography (OCT) in selected ACS patients with LTB. Among 85...
Background/Objective: Multislice computed tomographic (MSCT) angiography is a rapid and minimally invasive method for the detection of intracranial aneurysms. The purpose of this study was to compare MSCT angiography with digital subtraction angiography (DSA) in the diagnosis of cerebral aneurysms. Patients and Methods: In this cross sectional study we evaluated 111 consecutive patients [42(37....
