4 8/6/2013 All Politics Is Local And Other Rules of the Game I realized that I was facing the type of problem (with my oncology care) that I never permitted at Apple my treatment was fragmented rather than integrated. Nobody at Stanford seemed to be in charge of figuring out how nutrition was related to pain care and to oncology. I was being treated by oncologists, pain specialists, nutritionists, hepatologists, hematologists but not being coordinated in a cohesive way.. So he convened the team of the various Stanford specialists at his house to coordinate treatment 4

Neily et al: JAMA 2010; 304(15): What Really Catalyzed Integration of the Heart Team? SYNTAX Trial- Heart Team Requirement PARTNER Trial- Partner Clinic, Partner Service 5

30 Optimal Starting Position Pigtail in noncoronary cusp Oval Radiopaque catheter marker band appearing as a straight line Straight Line Target Implantation Depth Target implant depth is 4-6 mm (Marker Band 1 1.5) Due to valve profile and native annulus interaction, higher implantation provides greater radial interference. This consideration is especially important for larger anatomies Most implants should trend closer to 4 mm depth or less 4 mm 7

31 Optimal Starting Position Coaxial Alignment Target coaxial alignment of catheter and annulus Adjust catheter and guidewire tension to ensure valve is aligned within the annulus and perpendicular to the basal plane 8
