Key clinical message: Three-dimensional multiplanar analysis and real-time three-dimensional guidance using transesophageal echocardiography can help to identify and access the ideal position for transseptal puncture even in the presence of atrial septal occluders.
Abstract: Transseptal puncture (TSP) for the percutaneous mitral valve edge-to-edge repair (PMVR) after percutaneous atrial septal defect (ASD) closure is a rare and challenging issue. Here, we present a case illustrating the feasibility of real-time three-dimensional transesophageal echocardiographic guidance for TSP without ASD closure device injury.
Keywords: atrial septal defect closure; percutaneous mitral valve edge‐to‐edge repair; three‐dimensional transthoracic echocardiography; transseptal puncture.
