Aims: The currently stated optimal catchment population for a pPCI centre is 300,000-1,100,000, resulting in 200-800 procedures/year. pPCI centres are increasing in number even within small geographic areas. We describe the organisation and quality of care after merging two high-volume centres, creating one mega centre serving 2.5 million inhabitants, and performing ~1000 procedures/year. Methods and results: In this descriptive cohort study, we linked individual-level data from the national Central Population Register holding survival status with our in-hospital dedicated PCI database of baseline, organisational and procedural characteristics. Quality measures were treatment delays and 30-day all-cause mortality. In the three-year study period, 2,066 consecutive pPCIs were performed. After the fusion of the two centres, pPCI procedures increased by 102%, while door-to-balloon remained stable at 32 minutes. Up to 75.1% of patients were directly transferred by pre-hospital triage, of whom 82.7% had ECG-to-balloon <120 min, 92.6% had door-to-balloon <60 min. Thirty-day all-cause mortality remained low at 6.3%. Conclusions: This study challenges the stated maximal pPCI centre volume. The quality of a centre reflects governance, training, resources and pre-hospital triage, rather than catchment population and STEMI incidence, as long as a minimum volume is guaranteed. Resources can be utilised better by merging neighbouring centres, without negative effects on quality of care.
