TAVR Medtronic CoreValve® Subclavian Approach Clinical Data Carlos E. Ruiz M.D., Ph.D., FACC Director, Congenital, Valvular and Structural Heart Disease Program North Shore Long Island Jewish System Lenox Hill Heart and Vascular Institute of New York
Subclavian/Axillary: Right or Left Access Routes Most appropriate access route selected by MDT based on patient anatomical characteristics Direct Aortic Transfemoral Subclavian Right Antererior Minithoracotomy Upper Ministernotomy Subclavian/Axillary: Right or Left Left preferred (versus right) due to delivery pathway’s typically better alignment with native aortic valve anatomy and less obstructive interaction with cranial perfusion
Access Selection Criteria Subclavian artery luminal diameter and calcification Presence of ipsilateral IMA graft Aortic root angulation Approach Left Subclavian / Axillary Right Subclavian / Axillary Iliofemoral Aortic Root Angle* >70° >30° * Aortic root angle = angle between plane of aortic valve annulus and horizontal plane
Room Setup O1 O2 Option A Option B OR Key: O1 = Operator 1

Italian Experience Subclavian vs. Transfemoral. Presented at TCT 2011
Propensity Score Matching Propensity score matching was performed in order to derive a comparable group of transfemoral patients 141 TAVR Trans-subclavian 141 TARI Trans-femoral matched PAD 85% 21% P<0.0001 The propensity score was calculated for each patient using a logistic regression model which included the following variables: CAD Diabetes Pulmonary Hypertension Prior aortic Valvuloplasty Prior pulmonary edema Prior stroke LVEF Chronic renal failure Fragility To account fo potential differeences between transfemoral and trans-subclavian TAVI regarding the main clinical predictors of procedural success a propensity analysis was performed.

Results Overall Survival – 2 years (A.S.Petronio et al. TCT 2011)
Conclusions Subclavian access is safe and effective First alternative access route to PAD Reduced distance to aortic valve results in more direct catheter response Similar acute and 2-year results compared to femoral approach Less bleeding complications
