Effect of Valve Suture Technique on Incidence of Paraprosthetic Regurgitation and 10-Year Survival

Use of SC technique increases the risk of significant PPR after AVR and MVR compared with IN technique independent of the size of prosthesis, degree of annular calcification, disease of the excised valve, or the implanting surgeon. Although 10-year survival is independent of suture technique, SC technique increases the risk of redo valve replacement after AVR.
