Morbidity and Mortality in Adult Fontan Patients After Heart or Combined Heart-Liver Transplantation
Authors' conclusion
In our multicenter cohort, post-transplant survival improved over time. Late referral after Fontan failure and markers of failing Fontan physiology, including worse functional status, lower extremity varicosities, and venovenous collaterals, were associated with post-transplant mortality.
