Complex high-risk and indicated percutaneous coronary intervention for stable angina: Does operator volume influence patient outcome?

ConclusionsCHIP-PCI cases are an increasingly large population in contemporary PCI practice. Higher operator volumes were not associated with improved 12-month survival.Condensed abstractData were analyzed on all complex high-risk and indicated revascularization using percutaneous coronary intervention (CHIP-PCI) procedures in England and Wales between 2007 and 2014. CHIP-PCI as a percentage of total PCI increased from 28.1% in 2007 to 36.2% in 2014 (P < .001). Median total operator volume was 29 cases with higher volumes associated with more patient comorbidity and increasing procedural complexity. In-hospital major bleeding (P < .001 for trend), access site complications (P < .001) and coronary perforation (P = .002) all associated with increasing operator CHIP-PCI volumes. However, trends for in-hospital death (P = .394), and 12-month mortality (P = .638) were similar across the volume quartiles.
