Optimum age for performing Fontan operation in patients with univentricular heart.

The purpose of this study was to determine the optimal age for performing Fontan operation using data from the National Inpatient Sample. Our results showed that although the Fontan operation was most commonly performed at age 2 in the United States, age 3 is the optimum age for this procedure as evident by lower rate of in-hospital mortality, procedure-related complications, and rate of nonroutine home discharge when procedure is performed at age 3 years.
