Final answer:
Uhl's anomaly, also known as Parchment heart, is a rare congenital cardiac condition characterized by the severe thinning or absence of the right ventricular myocardium.
Step-by-step explanation:
Another name that identifies Uhl's anomaly is Parchment heart or right ventricular aplasia. This rare congenital condition involves the severe thinning or absence of the myocardial muscles in the right ventricle, leading to a heart with walls that have a parchment-like appearance. Uhl's anomaly is different from other cardiac conditions such as Barlow's syndrome (mitral valve prolapse), Ebstein's anomaly (where the tricuspid valve is abnormally formed), and Tetralogy of Fallot (which involves four heart defects including a ventricular septal defect, pulmonary stenosis, right ventricular hypertrophy, and an overriding aorta).
