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.)
