Ebstein's anomaly is a congenital heart defect in which the septal and posterior leaflets of the tricuspid valve are displaced downwards towards the apex of the right ventricle of the heart. [1] EA has great anatomical heterogeneity that generates a wide spectrum of clinical features at presentation and is complicated by the fact that the ...
English: 9-year-old girl with Ebstein's anomaly and Mahaim accessory pathway. ECGs recorded during sinus rhythm showing minimal pre-excitation, and during tachycardia (antedromic AVRT) showing maximal pre-excitation with LBBB morphology
ECGs during sinus rhythm and AVRT from a 9-year-old girl with Ebstein's anomaly and a Mahaim accessory pathway. Mahaim pathways are typically seen on the right side of the heart, with their ventricular connection lying within or close to the right bundle branch. [ 4 ]
The history of the group goes back to the early days of cardiac surgery in the mid 1950s, when 16 surgeons met annually to relate their early pioneering experience in operating on children with congenital heart defects.
People with WPW may have more than one accessory pathway – in some cases, as many as eight abnormal pathways have been found. This has been seen in individuals with Ebstein's anomaly. [14] Wolff–Parkinson–White syndrome is sometimes associated with Leber's hereditary optic neuropathy, a form of mitochondrial disease. [15]
Ebstein's anomaly [31] – about 50% of individuals with Ebstein anomaly have an associated shunt between the right and left atria, either an atrial septal defect or a patent foramen ovale. [32] Fetal alcohol syndrome – about one in four patients with fetal alcohol syndrome has either an ASD or a ventricular septal defect. [33]

Tricuspid valve stenosis itself usually does not require treatment. If stenosis is mild, monitoring the condition closely suffices. However, severe stenosis, or damage to other valves in the heart, may require surgical repair or replacement.
