Transposition of the great arteries
Transposition of the great arteries (TGA), also known as transposition of the great vessels (TGV), is the most common cyanotic congenital cardiac anomaly presenting during the newborn period, with cyanosis in the first 24 hours of life.
It occurs as a result of ventriculoarterial discordance, w...

Temporal resolution
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...

Myocarditis
Myocarditis (rare plural: myocarditides) is a general term referring to inflammation of the myocardium.
Diagnosis
Endomyocardial biopsy is considered the gold standard of diagnosis, although it is subject to sampling error and there is a risk of perforation or tamponade. It is graded according...

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. See the main article on transposition of the great arteries for discussion of the D-loop subtype....
