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

TAVR is Available in More Than 65 Countries Around the World

>250,000 total implants to date

Estimated Global TAVR Procedure Growth

In the next 10 years, TAVR growth will increase X4!

• 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?

Page 37: The TAVI Journey: Update on Evidence And Future trialscaci.org.ar › assets › uploads › tavi_perspectiva_dr_generaux.pdf · The TAVI Journey: Update on Evidence And Future trials

TAVR New Indications?

Page 38: The TAVI Journey: Update on Evidence And Future trialscaci.org.ar › assets › uploads › tavi_perspectiva_dr_generaux.pdf · The TAVI Journey: Update on Evidence And Future trials

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

Page 39: The TAVI Journey: Update on Evidence And Future trialscaci.org.ar › assets › uploads › tavi_perspectiva_dr_generaux.pdf · The TAVI Journey: Update on Evidence And Future trials

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

“In severe AS, an exercise test was performed in only 5.7%

of patients with no symptoms…”

“This under-use may be explained by an insufficient

implementation of the current guidelines and fear of

complications or inexperience in exercise testing…”

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

‘‘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.”

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

Five Year Results

Page 72: The TAVI Journey: Update on Evidence And Future trialscaci.org.ar › assets › uploads › tavi_perspectiva_dr_generaux.pdf · The TAVI Journey: Update on Evidence And Future trials

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

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
