Coronary Computed Tomography Angiography in the Assessment of Acute Chest Pain in the Emergency Room
The coronary computed tomography angiography has recently emerged as an accurate diagnostic tool in the evaluation of coronary artery disease, providing diagnostic and prognostic data that correlate directly with the data provided by invasive coronary angiography. The association of recent technological developments has allowed improved temporal resolution and better spatial coverage of the car...
BACKGROUND In patients with stable coronary artery disease (CAD), decisions regarding revascularisation are primarily driven by the severity and extent of coronary luminal stenoses as determined by invasive coronary angiography. More recently, revascularisation decisions based on invasive fractional flow reserve (FFR) have shown improved event free survival. Cardiovascular magnetic resonance (C...
OBJECTIVE To investigate the value of non-invasive reperfusion indices in acute myocardial infarction, avoiding the possible need for acute coronary angiography and subsequent angioplasty. DESIGN In a prospective angiographic study, seven potential ECG or clinical markers of reperfusion were analysed in 230 patients with acute myocardial infarction. In all patients two 12 lead ECGs were used:...
AIMS Left atrial (LA) volume can be determined during radiofrequency catheter ablation (RFCA) of atrial fibrillation (AF) with angiography or electro-anatomic (CARTO) mapping. We compared these volumes with LA volume measured using transthoracic real-time three-dimensional echocardiography (3DE). METHODS AND RESULTS One hundred and twenty-seven consecutive patients undergoing RFCA for AF were...
BACKGROUND Non-occlusive mesenteric ischemia (NOMI) is ischemia of the mesentery that is caused by hypoperfusion or vasospasm without any thrombosis. NOMI is difficult to diagnose by physical examination alone. Although angiographic examination of the superior mesenteric artery (SMA) is the usual diagnostic method used, it is an invasive examination. Usually, a long range of the bowel becomes d...
AIMS The Euro Heart Survey of Stable Angina set out to prospectively study the presentation and management of patients with stable angina as first seen by a cardiologist in Europe, with particular reference to adherence to existing guidelines and regional variability in patient presentation and initial assessment. METHODS AND RESULTS Consecutive outpatients with a clinical diagnosis by a card...
Summary Using CT in patients with stable angina can help diagnose obstructive and non-obstructive coronary heart disease improve the prognosis of patients. Purpose this study was to compare diagnostic accuracy conventional invasive angiography. A retrospective 142 consecutive from 2005 2014 conducted. All underwent angiography subsequent Patients without significant stenosis but typical anginal...
Computed tomographic angiography (CTA) is a well-established non-invasive investigation for this neurological presentation to exclude intracranial aneurysms. However, dural arteriovenous fistulae with anterograde venous drainage only can be missed by CTA. Here we reported two patients with painful complete third nerve palsy and dural carotid cavernous fistulae with anterograde venous drainage o...
