Tricuspid regurgitation (TR) is a valvular defect that allows backflow of blood from the right ventricle to the right atrium during systole. In addition, 10% to 45% of patients have accessory pathways, frequently multiple, which increase the risk of protracted arrhythmias that can produce cardiac failure and sudden cardiac death.

It is composed of striated, involuntary muscle cells connected to form the contractile pump to generate blood flow. Alternately, there may be tethering of the anterior leaflet that causesrestricted motion. Ebstein has also been associated with mutations in the NKX2-5 gene, which is a cardiac transcription factor responsible for the association between atrial septal defectswithatrioventricular conduction defects.
