• Device positioning is one of the most significant challenges in TAVI• Positioning-related complications reduce hemodynamic
improvement and may result in catastrophic clinical outcomes.1,2,3

Positioning-Related Complications
• Engager provides tactile control during deployment• Results from the CE Pivotal Trial demonstrate that Engager’s unique
design delivers simple, stable, and repeatable valve positioning1,2

Valve Embolization
Coronary Occlusion
Annular Rupture
Control Arms provide tactile control and
secure the valve during deployment-
Engager seals the annulus by capturing the native leaflets with the control arms and
conforming to the anatomy with the self-expanding frame
Fixation of the native leaflets and true commisure-to-
commisure alignment provides clearance for the coronary ostia.
Self-expanding frame conforms
to varying annular shapes

• Moderate and severe PVL have been associated with increased mortality with other transcatheter aortic valve systems.1,2
• Patients with moderate or severe PVL at 30 days: – Engager: 0%3
– Sapien XT: 24.2%4
Engager has Minimal PVL

Engager Valve Design
• Control arms
• Self-expanding nitinol frame and polyester skirt
• Supra-annular valve function
• Bovine pericardial tissue
• Tactile control during deployment
• 29 Fr equivalent TA delivery system
• Integrated introducer sheath
• Three step deployment
Engager TA Delivery System
The outer diameter of the integrated sheath is 10.7 mm
Benefits of the Engager System
1Simple and stable valve positioning because the control arms provide tactile feedback and
secure the valve during deployment
2Minimal paravalvular leak because the
control arms capture the native leaflets and the self-expanding frame conforms to the
annulus
3 Anatomic alignment provides clearance for the coronary ostia

(on behalf of the Engager Investigators)
• Optimal TAVI requires accurate valve positioning
• Engager TAVI System• Allows anatomically correct rotational positioning of the valve • Captures the native leaflets for sealing• Is expected to ensure optimal positioning of the valve within the annulus • Provides possible reduction of paravalvular regurgitation
• First report of the complete 30-day patient outcomes for all patients from the Engager European Pivotal Trial
Engager | Background
• Primary Endpoint: All-cause mortality at 30 days
• 100% of all subjects monitored
• Assessment by an independent echocardiography core lab
• All serious adverse events adjudicated by independent Clinical Events Committee
• Clinical and safety endpoints reported according to Valve Academia Research Consortium (VARC I) definition

Engager CE Pivotal | Valve Performance
Reported values reflect expert adjudicated evaluations. Calculated for all implanted patients (N=124).
Engager CE Pivotal | Pacemaker Implantation
• The Engager bioprosthesis can be implanted with a high degree of technical success by multiple operators and with an acceptable incidence of serious procedural complications
• The system restores effective aortic valve hemodynamic performance: it relieves aortic valve stenosis without inducing significant regurgitation
• The Engager TAVI system performs as intended with an acceptable risk/benefit ratio for patients with symptomatic, severe aortic stenosis who are at high or extreme risk for surgical aortic valve replacement.
