Deaths from unknown causes were assumed to be deaths from cardiovascular causes.
2
Acute kidney injury, stage III is defined as an increase in serum creatinine to
≥ 300% (3 x increase compared with
baseline) or serum creatinine of ≥ 4 mg/d (≥ 354 µmol/L) with an acute increase of at least 0.5 mg/dl (44 µmol/L)
within 72 hours of the procedure (per the VARC-1 definition).
3
Disabling bleeding: Fatal bleeding OR bleeding in a critical area or organ, such as intracranial, intraspinal,
intraocular, or pericardial necessitating pericardiocentesis, or intramuscular with compartment syndrome OR
bleeding causing hypovolemic shock or severe hypotension requiring vasopressors or surgery OR overt source of
bleeding with drop in hemoglobin of ≥ 5 g/dL or whole blood of packed red blood cells (RBC) transfusion ≥ 4 units
(Life-threatening per VARC-1 definitions).
4
Cardiac reintervention includes any intervention that repairs, alters or replaces a previously operated valve OR
balloon aortic valvuloplasty OR Surgical aortic valve replacement OR valve in valve.

Standardized endpoint definitions for transcatheter aortic valve implantation clinical trials consensus from the
Valve Academic Research Consortium (VARC). Events with missing or incomplete onset dates were excluded
from the analysis.
2
Kaplan-Meier estimates used the first event per patient. Events occurring after day 30 and day 365 were not
included in the analysis of the 30-day and 1-year results, respectively.
3
Confidence intervals calculated using Greenwood’s formula. The confidence intervals are calculated without
multiplicity adjustment. The adjusted confidence intervals could be wider than presented here. As such, confidence
intervals are provided to illustrate the variability only and should not be used to draw any statistical conclusion.
