- Aim of the present study was to verify the feasibility and accuracy of live integration of myocardial fibrosis evaluated at CCT with EAM (electro-anatomical mapping).
- Large multicenter studies and meta-analysis have documented the diagnostic accuracy and the prognostic implications of stress echocardiography, cardiac magnetic resonance and, mainly, nuclear stress tests. However, none of them provides a comprehensive anatomical and functional evaluation within the same study as stress CT perfusion. Myocardial CT perfusion is the only non-invasive modality that allows to quantifying coronary stenosis and determining its functional relevance, constituting a potential “one-stop-shop” method for the diagnosis and global management of patients with known or suspected coronary artery disease.
- Aortic valve calcification (AVC) is an active process that involves inflammation, disorganization of matrix disposition, lipid accumulation and lamellar bone formation. AVC without hemodynamic changes has been associated with cardiovascular (CV) risk factors and increased risk of coronary and CV events. Nowadays, echocardiography is the standard imaging technique to evaluate aortic valve pathologies. However, cardiac computed tomography (CT) allows high accuracy and reproducible measurement of AVC, without exposing the patients to excessive radiation or contrast administration.
- To assess evaluability and diagnostic accuracy of a low dose CT angiography (CTA) protocol for carotid arteries using latest Iterative Reconstruction (IR) algorithm in comparison with standard 100 kVp protocol using previous generation CT and IR.
- We sought to evaluate the additional value of left atrial appendage (LAA) 3D printing derived from computed tomography (CCT) in determining the size for LAA occlusion (LAAO) devices as compared to standard measurement by using occurrence of LAA leak as endpoint.
- A 71 years-old man was referred to our Center after detection of a non-sustained ventricular tachycardia (NSVT) at ambulatory electrocardiogram (ECG) monitoring. His previous cardiological history was negative. Rest ECG showed negative T-waves on V4 V6 leads (Panel A). Blood examination was normal including high-sensitive troponin-I and C-reactive protein. Transthoracic echocardiography showed normal biventricular wall kinesis and function. Cardiac CT (CCT) ruled out coronary artery disease but showed a hypodense region (−80 HU), consistent with a fibro-adipose tissue infiltration, in left ventricular (LV) lateral wall with sub-epicardial distribution (Panel B and C, red arrows).
