title: Three-dimensional echocardiography-guided repair of residual shunt after percutaneous atrial septal defect closure.
abstract: A 28-year-old woman was referred to closure of a residual shunt produced through a percutaneous device previously implanted in the atrial septum. The imaging protocol to guide the procedure included 2D TEE and real time 3D (RT3D) transesophageal echocardiography (TEE) imaging. RT3D TEE facilitated the evaluation of the defect morphology, and the relationship with the previous device, allowing a proper understanding of the mechanism responsible for the residual shunt. It was also a useful tool for guiding device deployment, providing clear intraprocedural information about catheter position and the spatial relationship with the previous device. In conclusion, RT3D TEE and 2D TEE are complementary techniques for the evaluation and guidance of transcatheter closure of complex atrial septal defects.
