Coronary angiography (CA) is an increasing diagnostic procedure in Belgium. The aim of this analysis was to look at the financial aspects of CA in a large tertiary Belgium hospital to establish if current reimbursement is appropriate. For the analysis of costs we considered the use of the catheterisation laboratory, personnel costs and material costs during multiple weekly periods in the spring of 2023. We calculated that one cathlab needs to perform 8.21 CA's to equal incomes with costs. To allow for a small positive income (200€) for the hospital/cardiologist 9 procedures per cathlab day are required. Our hospital performs a 7 (mean) ± 0.75 (standard deviation) of CA's per cathlab day and therefore does not reach this financial break-even point. Our calculations are on the safe side, since coronary physiological interrogation with fractional flow reserve (FFR) was excluded from this analysis. Nevertheless, this is a cost-effective technique for which no extra reimbursement is foreseen in the current Belgium system.
