Background: Estimating the risk for complications facilitates risk-benefit assessment and procedural planning in chronic total occlusion (CTO) percutaneous coronary intervention (PCI).
Methods: We analyzed the PROGRESS-CTO (Prospective Global Registry for the Study of Chronic Total Occlusion Intervention; NCT02061436) and created a risk score for pericardiocentesis. Patients with histories of coronary artery bypass graft surgery were excluded. Logistic regression prediction modeling was used to identify independently associated variables, and the model was internally validated with bootstrapping.
Results: Of the 7,672 CTO PCI cases performed between 2012 and 2022 at 40 centers, 83 (1.1%) required pericardiocentesis. The final prediction model identified predictors of pericardiocentesis: age ≥ 65 years (OR: 2.10; 95% CI: 1.27-3.46), 1 point; female sex (OR: 2.25; 95% CI: 1.39-3.63), 1 point; moderate to severe calcification (OR: 3.28; 95% CI: 1.96-5.49), 1 point; antegrade dissection re-entry (OR: 2.83, 95% CI: 1.45-5.51), 1 point; and retrograde strategy (OR: 3.50; 95% CI: 2.08-5.87), 2 points; with a bootstrap corrected C statistic of 0.78 (95% CI: 0.72-0.83). The calculated risk percentages for pericardiocentesis on the basis of the PROGRESS-CTO mortality score ranged from 0.18% to 8.74% for pericardiocentesis, and 55% of patients had PROGRESS-CTO pericardiocentesis scores of 1 or 2, corresponding to a pericardiocentesis risk of 0.4% to 1.6%.
Conclusions: The PROGRESS-CTO pericardiocentesis risk score can facilitate risk-benefit assessment and procedural planning in patients undergoing CTO PCI.
