  1. AVR Aortic Valve Replacement, CABG Coronary Artery Bypass Graft, FSA Foreign Surface Area, IVC Inferior Vena Cava, SSR Soft shell Reservoir, VARD Venous Air Removal Device. * We begin training junior perfusionists with Midi card and after experience is gained, we move to SSR for routine cases. With further experience both by surgical and perfusionist teams, we move forward to Soft Shell Reservoir (SSR) for all cases regardless of complexity. The characteristics of these two options are described below.
