Objectives
To analyze the epidemiological characteristics and trends in death after thoracotomy in children with congenital heart disease (CHD).
Methods
The clinical data of children with CHD aged 0–14 years who died after thoracotomy in our hospital from January 1, 2005, to December 31, 2020, were retrospectively collected to analyze the characteristics of and trends in postoperative death.
Results
A total of 502 patients (365 males; 72.7%) died from January 1, 2005, to December 31, 2020, with an average of 31 deaths per year. For these patients, the median age was 2.0 months, the median length of hospital stay was 16.0 days, the median postoperative time to death was 5.0 days, and the median risk adjustment in congenital heart surgery-1 (RACHS-1) score was 3.0. 29.5% underwent emergency surgery, 16.9% had postoperative ECMO support, and 15.9% received postoperative blood purification treatment. In the past 16 years, the deaths of children with CHD under 1 year old accounted for 80.5% of all deaths among children with CHD aged 0–14 years, and deaths (349 cases) under 6 kg accounted for 69.5% of all deaths. Age at death, weight, and disease type were characterized by annual changes.
Conclusions
The postoperative deaths of children with CHD mainly occurred in infants and toddlers who weighed less than 6.0 kg, and TGA and PA were the most lethal CHDs. The proportion of deaths has been increasing across the years among patients who are young, have a low body weight, and have complex cyanotic CHD.
