Transposition of the great arteries
Transposition of the great arteries (TGA) is the most common cyanotic congenital cardiac anomaly presenting during the newborn period, with cyanosis in the first 24 hours of life. It accounts for up to 7% of all congenital cardiac anomalies 1 and can be assessed with echocardiography, gated car...
Temporal resolution relates to the duration of time for acquisition of a single frame of a dynamic process, i.e., cine imaging. Discussion The concept of temporal resolution is fundamental to cardiac CT and MRI, in which a rapidly beating heart is imaged over the order of milliseconds into mul...
Myocardial bridging of the left anterior descending coronary artery
Published 27 Apr 2013
Computed tomography of the heart or cardiac CT is routinely performed to gain knowledge about cardiac or coronary anatomy, to detect or diagnose coronary artery disease (CAD), to evaluate patency of coronary artery bypass grafts or implanted coronary stents or to evaluate volumetry and cardiac f...
Myocarditis is a general term referring to inflammation of the myocardium. Clinical presentation Clinical presentation is variable in severity, ranging from asymptomatic to cardiogenic shock, but it typically is associated with other viral symptoms, including fever and malaise. It typically o...
Cardiac MRI consists of using MRI to study heart anatomy, physiology, and pathology. Advantages In comparison to other techniques, cardiac MRI offers: improved soft tissue definition protocol can be tailored to likely differential diagnoses a large number of sequences are available dynamic...
D-SPECT represents the next step in the evolution of SPECT technology and is based on a unique acquisition geometry. It has nine arrays of cadmium zinc telluride (CZT) detectors, each of which rotates around its central axis with programmable angular rotation 1. The detectors are very compact al...
Congenitally corrected transposition of the great arteries
Congenitally corrected transposition of the great arteries, also known as levo- or L-loop transposition (L-TGA), is a rare cardiovascular anomaly with inversion of the ventricles and great arteries. Epidemiology This anomaly comprises less than 1% of all congenital heart diseases 1,2,7. Clin...

Athlete heart syndrome
Athlete heart syndrome refers to adaptations in both cardiac structure and function seen in people engaged in high-performance and endurance physical exercise. Epidemiology The prevalence of the condition has increased due to the increased popularity of recreational exercise, approx 3.6/100,00...
