Single Ventricle Program

The Single Ventricle Program is for children who are born with only one pumping chamber (single ventricle) in their heart, instead of the usual two.

A broad range of congenital cardiac conditions are associated with having a single ventricle, including

Children born with single ventricle congenital heart defects have a series of operations during childhood, including Norwood, Glenn and Fontan operations. Specific complications that need to be monitored include ventricular dysfunction, atrioventricular valve regurgitation, arrhythmia, cyanosis, thrombosis, protein-losing enteropathy and plastic bronchitis. Liver fibrosis and renal dysfunction are common and may progress over time, and cognitive, neuropsychological and behavioral deficits are also highly prevalent.

Our program seeks to improve survival and quality of life for children and young adults with single ventricle physiology. We seek to educate parents regarding the care of their child and provide resources.

This program provides comprehensive and interdisciplinary care, screening, evaluation and coordinated care, and referrals for the following areas:
