Surgery for Adult Patients with Congenital Heart Disease: Results from the European Database

Abstract

Adults with congenital heart disease (ACHD) represent a growing population. To evaluate frequency, type and outcomes of cardiac surgery in ACHD, we gathered data from the European Congenital Heart Surgeons Association Database of 20,602 adult patients (≥18 years) with a diagnosis of congenital heart disease who underwent cardiac surgery, between January 1997 and December 2017. We demonstrated that overall surgical workload (as absolute frequencies of surgical procedures per year) for this specific subset of patients increased steadily during the study period. The most common procedural groups included septal defects repair (n = 5740, 28%), right-heart lesions repair (n = 5542, 27%) and left-heart lesions repair (n = 4566, 22%); almost one-third of the procedures were re-operations (n = 5509, 27%). When considering the year-by-year relative frequencies of the main procedural groups, we observed a variation of the surgical scenario during the last two decades, characterized by a significant increase over time for right and left-heart lesions repair (p p p = 0.03). Overall hospital mortality was 3% (n = 622/20,602 patients) and was stable over time. An inverse relationship between mortality and the number of patients operated in each center (p < 0.0001) was observed.
