Risk factors of 30-day mortality following cardiac surgery in adults with congenital heart disease: analysis from the Japanese registry

Abstract Background With advancements in pediatric therapies, the adult congenital heart disease (ACHD) population has grown consistently. ACHD patients often face complications necessitating cardiac surgery, and understanding surgical risk factors is essential. Purpose This study aims to assess ACH...

description Abstract Background With advancements in pediatric therapies, the adult congenital heart disease (ACHD) population has grown consistently. ACHD patients often face complications necessitating cardiac surgery, and understanding surgical risk factors is essential. Purpose This study aims to assess ACHD surgical risk factors using big data, addressing evidence gaps in previous research limited to univariate analysis due to few perioperative adverse events. Methods We analyzed the Japanese Registry of All Cardiac and Vascular Diseases-Diagnosis Procedure Combination (JROAD-DPC) database from April 2013 to March 2020. The JROAD-DPC database covers nearly all teaching hospitals with cardiovascular beds participation in JROAD. Our study included ACHD patients (>15 years) undergoing open-heart surgery. Our primary outcome was 30-day mortality. We assessed clinical backgrounds, admission status, treatment, and length of hospital stay. Results Out of 13,677 ACHD patients (mean age: 53 years, females 47%) undergoing cardiac surgery assessed for 30-day mortality, 13,516 (98.8%) patients were categorized into the survival group and 161 (1.2%) into the death group. Mortality rates varied by complexity of congenital heart disease (CHD): 0.8% for simple, 1.8% for moderate, and 0.9% for great. The figure shows that a significant increase in 30-day mortality rates with age was demonstrated in simple and moderate complexity (p

The figure shows that a significant increase in 30-day mortality rates with age was demonstrated in simple and moderate complexity (p&lt;0.001 for trend analysis in both categories). In contrast, for cases of great complexity, the increase in 30-day mortality rates with aging was not statistically significant (p=0.443). The death group was significantly older and had higher rates of ambulance admissions, renal disease, and peripheral vascular disease. Intra-aortic balloon pumps (IABP), veno-arterial extracorporeal membrane oxygenation (VA-ECMO), and dialysis during hospitalization were significantly higher among deceased patients. Length of ICU stay was significantly longer in the death group (median [IQR]; 3 [2-4] vs. 6 [3-11], p&lt;0.001). Cox proportional-hazards model showed that age, moderate complexity, emergency admission, hospital bed counts, renal disease, and use of IABP and VA-ECMO were independently associated with 30-day mortality (Table). Conclusions The present study, which utilizes the nationwide administrative DPC database, demonstrates that surgical outcomes for patients with ACHD, as measured by 30-day mortality rates, are generally favorable. These outcomes significantly depend on factors such as age, complexity of CHD, emergency admissions, hospital capacity, renal disease, and use of mechanical circulatory support.</description><identifier>ISSN: 0195-668X</identifier><identifier>EISSN: 1522-9645</identifier><identifier>DOI: 10.1093/eurheartj/ehae666.2117</identifier><language>eng</language><publisher>US: Oxford University Press</publisher><ispartof>European heart journal, 2024-10, Vol.45 (Supplement_1)</ispartof><rights>The Author(s) 2024.
