RESUMO
In 2021 a total of 5439 patients were included by 22 participating centers. In total 3721 surgical, 3413 interventional and 34 hybrid procedures were performed during 6122 hospital stays. 2220 cases (36.3%) could be allocated to the 15 index procedures. The mean unadjusted in-hospital mortality ranged from 0.4% among interventional and 2% among surgical cases up to 6.2 % in cases with multiple procedures. In-hospital mortality among index procedures accounted for 2.3% in TCPC, 20.3% in Norwood procedures and 0.4% following interventional closure of patent ductus arteriosus. For the remaining 7 surgical and 5 interventional index procedures no in-hospital deaths were recorded. The 10 years longitudinal evaluation of 1795 patients after tetralogy of Fallot repair revealed repeat interventional or surgical procedures in 21% of the patients. Over the same period 31.1% of 2037 patients, following initial treatment of native coarctation, required at least one additional hospital admission, 39.4% after initial interventional and 21.3% after initial surgical therapy. Conclusion The annual report 2021 of the German Registry for Cardiac Operations and Interventions in CHD shows continuously good results in accordance with previous data of the registry. Compared to international registries on CHD it can be ascertained that in Germany invasive treatment of CHD is offered on a high medical level with excellent quality. The proven fact that patients with various malformations like tetralogy of Fallot and coarctation of the aorta require repeat procedures during follow-up confirms the urgent requirement of longitudinal assessment of all patients presenting with complex lesions.
