Clinical outcomes stratified by presence of persistent peridevice leak at 12 months

	No PDL or Grade 1 PDL		New or persistent Grade 2–3 PDL
	n = 60		n = 93
	Events, n (%)	Events per 100 patient‐years	Events, n (%)	Events per 100 patient‐ years
Composite outcome	16 (27)	11.2 (6.9–18.4)	36 (39)	17.3 (12.4–23.9)
Ischemic stroke	4 (6.6)	2.9 (1.1–7.9)	11 (12)	5.3 (2.9–9.5)
Transient ischemic attack	3 (5)	2.1 (0.6–6.5)	0	0
All‐cause death	9 (15)	7.1 (3.7–13.7)	25 (27)	13.3 (8.9–19.6)

Note: Event rates are presented at events per 100 patients‐years (95% confidence interval).

Abbreviations: CI, 95% confidence interval; HR, hazard ratio; PDL, peridevice leak; SE, systemic embolism; TIA, transient ischemic attack.
