Fontan procedure

 [faw-tah´]
functional correction of a tricuspid atresia by anastomosis of, or insertion of a nonvalved prosthesis between, the right atrium and the pulmonary artery with closure of the interatrial communication.

Fon·tan pro·ce·dure

(fon-tān'),
placement of a conduit (usually valved) from the right atrium to the main pulmonary artery as a bypass to a hypoplastic right ventricle, as in tricuspid atresia.
Synonym(s): Fontan operation

Fontan procedure

A surgical procedure for toddlers (children aged 3 to 5), who have hypoplastic left-heart syndrome, which creates a cavopulmonary shunt with a lateral tunnel, deviating blood from the inferior vena cava to the pulmonary artery, bypassing the right ventricle.
