For the general cardiologist a compact and up-to-date indications list for CMR exams with illustrative examples is provided covering the entire field of cardiology with 16 chapters. For the CMR expert updated state-of-the-art CMR protocols are given.
This issue of Cardiac Electrophysiology Clinics, guest edited by Mohammad Shenasa and Amin Al-Ahmad, will focus on Advances in Cardiac Mapping and Catheter Ablation. This is part one of a two-part issue and will include articles centered around Basic Concepts in Cardiac Mapping, Novel Mapping & Imaging Systems & Technologies, and Catheter and Energy Sources. Topics include, but are not limited to, Embryology of the Cardiac Conduction System Relevant to Cardiac Arrhythmias; Anatomical Consideration Relevant to Atrial and Ventricular Arrhythmias; Fundamentals of Cardiac Mapping; Novel Cardiac Mapping Systems; Non-invasive Mapping & ECGI in Atrial and Ventricular Arrhythmias; Optical Mapping; Omnipolar Mapping; Cardiac CT, MRI, and Fibrosis Quantification; High resolution mapping in patients with atrial and ventricular arrhythmias; Contact Force and Ablation Index; and New Catheter Balloons Including Radiofrequency.
Abstract: The aim of this paper is to evaluate the diagnostic image quality of spectral dual-source photon-counting detector coronary computed tomography angiography (PCD-CCTA) for coronary artery disease in a multicenter study. The image quality (IQ), assessability, contrast-to-noise ratio (CNR), Agatston score, and radiation exposure were measured. Stenoses were quantified and compared with invasive coronary angiography, if available. A total of 92 subjects (65% male, age 58 ± 14 years) were analyzed. The prevalence of significant coronary artery disease (CAD) (stenosis ≥ 50%) was 17% of all patients, the range of the Agatston score was 0-2965 (interquartile range (IQR) 0-135). The IQ was very good (one, IQR one-two), the CNR was very high (20 ± 10), and 5% of the segments were rated non-diagnostic. The IQ and assessability were higher in proximal coronary segments (p
Atrial fibrillation is a heart condition that causes an irregular and often abnormally fast heart rate. It can cause problems including dizziness, shortness of breath and tiredness and a patient may be aware of noticeable heart palpitations, where the heart feels like it is pounding, fluttering or beating irregularly, often for a few seconds or, in some cases, a few minutes (NHS Choices). This comprehensive guide presents clinicians with the latest developments in the diagnosis and management of atrial fibrillation. Divided into seven sections, the book covers clinical spectrum, diagnosis, therapeutic strategies, interventions, and new technologies used in its treatment and prevention. Compl...
