Values are % unless indicated. Study by Villa is represented by “a” and “b” as Villa chose to compare cohorts by valve type (S vs. M, L, XL). The study by Miceli chose to compare cohorts by incision hence those values with & represent cohort approached via ministernotomy. Folliguet** chose to compare cohorts aortic cross clamp and cardiopulmonary bypass times for isolated AVR hence # values represent patients undergoing surgery via sternotomy. *, represents the study by Shrestha 2013. RT, right anterior thoracotomy; Mini, ministernotomy; Stern, sternotomy; Redo, redosternotomy; Add pro, additional cardiac procedure; AVR, aortic valve replacement; S, M, L, XL, Perceval S valve types; NR, not reported.
