(A) Drawing of a central edge-to-edge (Alfieri) repair shown from the surgeons' perspective. (B) Two dimensional transesophageal echocardiographic (TEE), transgastric short axis view after edge-to-edge repair highlighting the double-orifice geometry in B-mode and Color Doppler echocardiography. (C) Still image of the mitral valve after edge-to-edge repair captured from a three-dimensional TEE, full volume data set shown en-face from the left atrial perspective. (D) Measurement of peak and mean transmitral mitral pressure gradient (TMPG) obtained with continuous-wave Doppler from the midesophageal four-chamber view following an edge-to-edge repair.

Transmitral Pressure Gradients in edge-to-edge versus conventional mitral valve repairs.
(A) Transmitral mitral pressure gradients (TMPG) were determined after separation from cardiopulmonary bypass and are shown for all patients after edge-to-edge and conventional mitral valve repairs. Values represent the mean ±SEM for n = 84. *P<0.0001 vs. conventional repair. (B) TMPG after edge-to-edge repair were performed in isolation (n = 29) or in combination with an annuloplasty ring (n = 52). There were no differences in TMPG with the addition of an annuloplasty system.
