Figure 1a: Three-dimensional transoesophageal echocardiography (TEE) imaging of the mitral ring dehiscence.
Figure 1b: The first jet was originating from the perimitral ring(arrow) and the second jet(asterisk) was arising from the basal portion of the posterior mitral leaflet.
Figure 1c: Image of the defect in the basal portion of the posterior mitral leaflet in the mid-esophageal TEE view.
Figure 1d: Rise of the mitral regurgitation jet from the defect in the basal portion of the posterior mitral leaflet possibly occurred after the separation of mitral ring suture.
Video 1: Rocking motion of the prosthetic mitral ring was present in the bicommissural TEE view.
Video 2: Three-dimensional transesophageal echocardiography (TEE) imaging of the mitral ring dehiscence.
Video-3: Severe mitral regurgitation(MR) was observed in the mid-esophageal TEE views with two distinct jets, the first MR jet was originating from the perimitral ring(asterisk) and the second one was arising from the basal portion of the posterior mitral leaflet(arrow) which was suitable with the location of the mitral ring suture.
Video-4: Dehiscence of the mitral ring possibly caused the occurrence of a defect in the posterior mitral leaflet in the junction zone and this defect emerged as another source of MR.
