Current Guidelines for TAVR?
Severe Aortic Stenosis
• Class I
TAVR is recommended in patients who meet
an indication for AVR who have a prohibitive
risk for surgical AVR and a predicted post-
TAVR survival greater than 12 months
• Class IIA
TAVR is a reasonable alternative to surgical
AVR in patients who meet an indication for
AVR and who have high surgical risk for
surgical AVR
Nishimura et al. J Am Coll Cardiol. 2014; 63(22):e57-185
TAVR is Available in More Than 65 Countries Around the World
>250,000 total implants to date

• The conclusions from the PARTNER 2A
randomized trial and this propensity score analysis
provide strong evidence that in intermediate-risk
patients with severe aortic stenosis, SAPIEN 3
TAVR compared with surgery improves clinical
outcomes and is the preferred therapy.

• 1st Final Thoughts…
TAVR Journey - 2016
The ultimate role of TAVR is yet to be
determined. But we can foresee a future
time when the use of TAVR (vs. surgery)
will be a risk-benefit assessment based
upon clinical and anatomic factors, and
not an imprecise risk stratification model!
Are We There Yet?
TAVR New Indications?
New Indications for TAVR?
• Where SAVR already succeeded
Symptomatic Severe AS for intermediate-risk
Symptomatic Severe AS for low-risk
Bicuspid
Pure Aortic Regurgitation
Concomitant AS and CAD
Concomitant AS and other valvular/heart disease
• Where SAVR makes sense but is struggling…
Asymptomatic Severe AS
Symptomatic Moderate AS
Severe AS in shock
Why TAVR could go where SAVR did not?
How TAVR different than SAVR?
• Less invasive
• Less peri-procedural mortality and co-
morbidity
• Better tolerability in case of instability
• Immediate recovery
• Larger effective orifice area (EOA)
with TAVR vs. SAVR

Asymptomatic Severe AS:
Rationale for Early AVR
Pros • Reduce irreversible
myocardial damage and subsequent consequences
• Decreased operative risk for asymptomatic patients
• AS progression highly variable; potential for a very rapid deterioration
• Risk of late (or too late) symptoms reporting
• Sudden death without preceding symptoms
Cons • Mortality potentially low among
a specific subset of low-risk and truly asymptomatic patients with normal stress test and stress echo
• Frequent follow-up could potentially identified patients ready for AVR in a timely fashion
• Inherent mortality and morbidity of AVR
• Long-term complication of AVR (anticoagulation, need for re-op, endocarditis, thrombosis, etc.)
Practical Issues with
“Watchful Waiting” Strategy
• Clinicians still have a fear of stress test with Severe AS patients; low penetration and underused
• Stress Imaging requires expertise and specific set-up that most community hospitals don’t have
• Sub-optimal follow-up and lost of follow-up are frequent
• Many sudden deaths occurred in Asx patients with no Class I indication of AVR and no preceding symptoms
• “Wishful Thinking” Strategy…
What is the Prevalence of
Asymptomatic Severe AS?
• ~40-50% of all Severe AS from major echo databases 1,2,3
~10-20% are bicuspid
~20-25% have multiple valve disease, clinically significant CAD, prior AVR
• Isolated Asymptomatic Severe AS represents ~25-30% of all Severe AS referred to Echo lab
• ~500,000 patients >65 years old in US4

Should and could we recommend
an early intervention strategy for
“truly” Asymptomatic Severe
Aortic Stenosis patients?
‘‘Low hospital mortality tends to justify a policy of
accepting patients for operation earlier in the natural
progression of their disability, because it is recognized
that there is a definite risk of rapid deterioration or
sudden death in the earlier policy of deferring
operation patients until their disability had become
definite and progressive and until their cardiac reserve
was nearly depleted.”

But what if you “only” have moderate AS and still
have recurrent symptoms of heart failure despite
optimal medical therapy?

Conclusions: TAVR Future Indications
• TAVR will go where SAVR went if
anatomically suitable…
• TAVR may go where SAVR struggled,
failled, or never been before!

Mid Term Hemodynamic Trends and Between Echo Changes in Transcatheter Aortic Valves in the PARTNER 1 Trial:

on behalf of The PARTNER Trial Investigators
and The PARTNER Publications Office
Five Year Results
Background and Aims
• TAVR is a safe and effective treatment for severe aortic stenosis
• THV long term durability, potential for deterioration, and any
implications for patient outcomes, are incompletely understood
• The PARTNER 1 trial provides a rich, existing data resource to
address the following two aims:
– Determine the longitudinal hemodynamic profile of THVs and
factors associated with early and mid-term trends
– Assess the incidence and clinical correlates of large interval
changes in valve parameters

Health Status Benefits of Transcatheter vs. Surgical Aortic Valve Replacement in Patients with Severe Aortic Stenosis at Intermediate Surgical Risk
Results From The PARTNER 2 Trial
David J. Cohen, MD on behalf of The PARTNER Trial Investigators
and The PARTNER Publications Office
Study Objectives
1. To compare health-related quality of life outcomes
among patients with severe AS and intermediate
surgical risk treated with either TAVR or SAVR
2. To determine whether the QOL benefits of TAVR
vs. SAVR vary over time
3. To examine whether the QOL benefits of TAVR
vs. SAVR in the intermediate risk population differ
according to access site or other patient
characteristics
SENTINEL Study Design (TAVR RCT)
Population: Subjects with severe AS with
clinical indications for TAVR with the
Edwards Sapien THV/XT/S3 or Medtronic
CoreValve/Evolut-R
N=296 subjects randomized 1:1:1
at sites in the U.S and Germany.
