title: Mitral paravalvular leak closure by antegrade percutaneous approach: three-dimensional transesophageal echocardiographic guided multiple Amplatzer implantation by a modified sequential anchoring-based technique.
abstract: We describe the technical aspects and the possible advantages of a modified anchoring-based technique for the implantation of multiple Amplatzer devices, in a case of large anteroseptal mitral paravalvular leak causing massive regurgitation, which was manaed by antegrade transseptal, single-stage, percutaneous approach. Real-time three-dimensional transesophageal echocardiographic guidance was crucial to ensure successful recrossings of the target defect and the optimal anatomical closure.
