Introduction Cardiac Surgery has been continuously performed for 50 years in Northern Ireland. Clearly, practice will have changed over this time and we have examined how this has evolved over the past decade.
Methods Data on 8922 patients operated on between 1st April 2008 and 31st March 2018 was taken from the prospectively maintained surgical database (PATS). Paediatric and adult congenital heart surgery patients were excluded. Cases were categorised and totalled for each of the ten years studied.
Results There was been a steady decrease in the ratio of CABG: Non-CABG cases performed as shown in figure 1. The increase in Non-CABG due to an increase in both isolated AVR and Other cases as shown in figure 2. Over the ten year period there were large increases in the amount of thoracic aortic aneurysm and tricuspid valve surgery performed. The ratio of biological: mechanical prosthetic valves steadily increased.
Conclusions Cardiac surgery continues to evolve and there has been a rise in the number of cases that are not isolated CABG or AVR. These operations are typically more complex e.g. thoracic aortic aneurysm or tricuspid valve surgery and this has implications for funding and delivery of cardiac surgery.
