Ballondilatation of atrial septum after transseptal puncture can be useful to bring the mitral clip delivery system to the left atrium

Purpose: Mitral clip case report to show how ballondilation can be used to widen the puncture site in the atrial septum after transseptal puncture Material and methods: 10 mm/40 mm over the wire ballon to dilate the transseptal puncture site 3dTEE guiding during the procedure. Results: After dilation the transseptal puncture site is large enough to allow the passage of the mitral clip delivery system. Fig. 1: The Balloncatheter is inflated Conclusion: Ballondilation could be useful for passage of the mitral clip delivery system in patients with a narrow fossa ovalis or a stiff interatrial septum.
