Percutaneous Coronary Intervention in Patients Undergoing Transcatheter Aortic Valve Implantation: A Systematic Review and Meta-Analysis with Reconstructed Individual Patient Data and GRADE Assessment.

Coronary artery disease coexists in approximately 50% of transcatheter aortic valve implantation candidates, yet the role of percutaneous coronary intervention (PCI) remains uncertain. We conducted a systematic review and meta-analysis of randomized controlled trials comparing PCI with conservative management or deferral in transcatheter aortic valve implantation candidates with coronary artery disease. We searched 4 databases from inception to June 19, 2026. Odds ratios (ORs) were pooled using random-effects models with restricted maximum likelihood estimation and Hartung-Knapp-Sidik-Jonkman adjustment. Individual patient data were reconstructed from published Kaplan-Meier curves. Risk of bias and certainty of evidence were assessed. Three randomized controlled trials (n = 1156 patients) were included. PCI showed no significant reductions in all-cause death (OR 0.88; 95% confidence interval [CI], 0.62-1.25; I2 = 0%), cardiovascular death (OR 0.72; 95% CI, 0.40-1.29; I2 = 0%), or myocardial infarction (OR 0.85; 95% CI, 0.17-4.18; I2 = 51.8%). Stroke was significantly reduced with PCI (OR 0.68; 95% CI, 0.48-0.95; I2 = 0%). PCI was associated with a trend toward increased any bleeding (OR 2.26; 95% CI, 0.81-6.29; I2 = 69.8%) and major bleeding (OR 1.70; 95% CI, 0.63-4.60; I2 = 35.9%).
