Abstract
BACKGROUND: Suboptimal stent delivery and deployment in calcified coronary lesions are associated with a poor clinical outcome. METHODS: Using the National Inpatient Sample database, we identified patients undergoing percutaneous coronary intervention (PCI). Comparison between procedural and hospital outcomes between patients who underwent atherectomy and those who did not. RESULTS: A total of 2,035,039 patients underwent PCI, of which 50,095 (2.4%) underwent lesion modification using atherectomy. After adjustment for baseline differences, patients who underwent atherectomy were found to have higher rates of in-hospital mortality (3.3% vs 2.2% adjusted Odds Ratio, aOR, 1.39; 95% confidence interval [CI], 1.31-1.46, P < 0.001), coronary artery dissection (1.7% vs 1.1%, aOR, 1.56; 95%, 1.45-1.67, P < 0.001) vascular complications (1.6% vs 1.0%, aOR, 1.52; 95%, 1.42-1.64, P < 0.001), major bleeding (6.3% vs 4.7%, aOR, 1.24; 95%, 1.18-1.28, P < 0.001), and acute kidney injury (AKI) (10.9%vs 9.1%, aOR, 1.07; 95%, 1.04-1.11, P < 0.001) when compared with non-atherectomy patients. Concomitant intravascular ultrasound (IVUS) imaging improved mortality, while other complication rates were not affected by imaging. CONCLUSION: Coronary atherectomy was performed in patients with multiple comorbidities and was associated with higher in-hospital mortality and complications than the non-atherectomy group.
