9 PEVAR provides benefits across the health care delivery spectrum* Patient Benefits Physician Benefits Hospital Benefits Minimally Invasive Lower anesthesia time Avoid GA complications Less blood loss Fewer groin complications Less pain Quicker recovery time Quicker procedure No anesthesia delay Patient satisfaction Improved efficiency Patient satisfaction Lower infection rates Lower cost Less blood transfusion Improved efficiency *As reported in single center publications

10 Several factors may contribute to success! Patient-specific 1 Physician-specific 2 Device-specific 3 Vessel Diameter Vessel Calcification Body Mass Index Gender Vessel Tortuosity Experience -SMCD Presence of multispecialty team Use of ultrasound AAA Endograft Sheath-based Delivery Profile Suture-mediated Closure Device Presence of PAD 1 Lee et al.

12 How to further reduce morbidity/mortality and the cost of EVAR? 1. Percutaneous Femoral Artery Access and Repair, 2. Local Anesthesia and Conscious Sedation Texas Heart In

13 Texas Heart Institute Fast-track EVAR ( ) Bilateral percutaneous access whenever possible using a pre-close technique (Prostar or ProGlide) (PEVAR) Local anesthesia and conscious sedation No Foley catheter No CVL No radial line No NG tube Interventional floor admission (No ICU) Ambulate in 4-8 hrs Normal diet within 2 hrs post procedure Next-day discharge

14 Texas Heart Institute Fast-Track EVAR RESULTS : 1457 pts. (78% ) Since 2000: 98% Prostar technical success: 97% ProGlide techical success: 96% Blood transfusion: 2% Conversion to General Anesthesia: 0.1% Hospital mortality: 0.3% Access site infection: 1%

15 LIFE Study Least Invasive Fast-Track EVAR Screening During Procedure Post Procedure Plan for success Minimize complications Minimize hospital stay Suitable for P-EVAR with Ovation Prime No comorbidities requiring extended hospitalization Percutaneous access Local/regional anesthesia No ICU if not required Early ambulation &diet Next day discharge TriVascular Ovation Prime Abdominal Stent Graft System

16 In the Next Decade We Will See Increasing Use of VCD Increasing trend for outpatient PCI and other intrventions, which will require safe and early ambulation Increasing demand for large profile device use and desire to avoid arterial cut-downs such as for EVAR, TEVAR & TAVR

20 Summary There is ample evidence from many single center studies and randomized PEVAR Trial that PEVAR offers significant benefits in comparison to SEVAR. Fast-track EVAR protocol characterized by percutaneous access and local anesthesia has enabled us to further reduce morbidity, procedure time, time to diet, time to ambulation, LOS and cost. New generation dedicated large bore closure devices offer encouraging preliminary results
