Authors' conclusion

In patients with concomitant coronary artery disease and severe aortic stenosis, the residual myocardial risk significantly affects TAVI outcomes. In particular, a rBCIS-JS >4 is associated with higher rates of major adverse cardiac and cerebrovascular events at 2 years.

Study context

Population
Patients with coronary artery disease and severe aortic stenosis undergoing transcatheter aortic valve implantation (TAVI), stratified by residual myocardium at risk (British Cardiovascular Intervention Society Jeopardy Score (BCIS-JS)) after a planned coronary revascularizationpatients enrolled, 294 pairs of patients were selected by propensity matching and compared
Participants
2,407 patients
Exposure
patients with residual BCIS-JS (rBCIS-JS) >4 compared with patients with rBCIS-JS ≤4
Outcome
Composite of:
  • All-cause death
  • Nonfatal myocardial infarction
  • Nonfatal stroke
  • Rehospitalization for heart failure
Follow-up
2 years
