1 Aortic Valve Periprosthetic Leakage: Anatomic Observations and Surgical Results 
Giuseppe De Cicco, MD, Roberto Lorusso, MD, PhD, Andrea Colli, MD, Francesco Nicolini, MD, Claudio Fragnito, MD, Teresa Grimaldi, MD, Bruno Borrello, MD, Alessandro Maria Budillon, MD, Tiziano Gherli, MD, Cesare Beghi, MD  The Annals of Thoracic Surgery  Volume 79, Issue 5, Pages (May 2005) DOI: /j.athoracsur Copyright © 2005 The Society of Thoracic Surgeons Terms and Conditions

2 Fig 1 Partition of aortic annulus adopting a clock format. (LCS = left coronary sinus; NCS = noncoronary sinus; RCS = right coronary sinus.) The Annals of Thoracic Surgery  , DOI: ( /j.athoracsur ) Copyright © 2005 The Society of Thoracic Surgeons Terms and Conditions

3 Fig 2 Location and extent of periprosthetic leakage. Cases with leakage into the sector between hour 4 and hour 8 (n = 19). Cases with leakage into the sector between hour 8 and hour 4 (n = 20). (LCS = left coronary sinus; NCS = noncoronary sinus; RCS = right coronary sinus.)

4 Fig 3 Relationship between the sector of periprosthetic leakage occurrence and the anatomy of the aortic annulus. (LCS = left coronary sinus; LVB = lateral aspect of left ventricular base; Me-Mu = muscular-membranous part of septum; Mu = muscular part of septum; MVAL = mitral valve anterior leaflet; NCS = noncoronary sinus; RCS = right coronary sinus.)
