Role of coronary angiogram before transcatheter aortic valve implantation

Figures

• 

  Figure 1. Primary endpoint of transcatheter aortic valve implantation patients stratified according to whether coronary angiogram was performed. Kaplan-Meier curves comparing cumulative incidence of all-cause mortality, myocardial infraction, repeat coronary angiogram, and re-admission to hospital with heart failure in patients with underwent coronary angiogram (in red) versus those who did not undergo coronary angiogram (blue). HR: Hazard ratio.

• 

  Figure 2. The incidence of the primary endpoint and heart failure readmission according to obstructive nature of coronary lesions. There was no difference in the incidence of the primary endpoint or readmission with heart failure between patients with obstructive versus non-obstructive coronary lesions.

• 

  Figure 3. The incidence of the myocardial infarction and repeat coronary angiogram according to obstructive nature of coronary lesions. There was no difference in the incidence of myocardial infarction between patients with obstructive versus non-obstructive coronary lesions. Patients with flow limiting lesions were more likely to have repeat coronary angiograms following transcatheter aortic valve implantation procedure.
