Predicting 10-year mortality in adults with congenital heart disease

Background: Advances in the management of patients with congenital heart disease (CHD) have made survival to adulthood an expectation. Although the literature is limited, existing evidence suggests that adult co-morbidities may be at least as prevalent in patients with CHD, if not more so, than in an age-matched general population. The presence of these co-morbidities in combination with underlying CHD likely places these patients at increased risk for early mortality. Thus, we sought to determine the predicted 10-year mortality risk in a cohort of adults with CHD. Methods: In this single center study, we administered a survey to patients ≥18 years of age with CHD to assess their 10-year mortality risk. Results: A total of 406 patients agreed to participate. The median age was 41.8 ± 15.3 years, and 58% were female. The average predicted 10-year mortality for the CHD cohort was 13.7 ± 15.8%. For CHD patients ≥50 years of age, the average 10-year mortality risk was 29.8 ± 3.0% compared to 26.1% ± 0.2% in the general population (p
