  • Prospective cohort study
  • consecutive patients

Authors' conclusion

The presence of severe AWT on preprocedural multidetector computed tomography is strongly associated with thromboembolic complications including stroke and mortality after TF TAVR.

Study context

Population
Patients undergoing transfemoral (TF) transcatheter aortic valve replacement (TAVR) for severe AS, January 2011 to April 2022
Participants
641 patients
Exposure
Severe aortic wall thrombus (AWT) vs no severe AWT
  • Severe AWTn = 73
Outcome
Composite of procedural thromboembolic events (ischemic stroke, blue toe syndrome, bowel ischemia or other solid organ infarction)
