Atrial Septal Defect Closure for Right-to-Left Shunting Following a MitraClip Repair.

: Percutaneous repair of the mitral valve has been widely adopted for the treatment of primary, symptomatic severe mitral regurgitation in patients at prohibitive risk for surgical intervention. We present a case of an elderly female patient with moderate-to-severe mitral regurgitation who underwent MitraClip procedure, with postprocedural course remarkable for the development of right-to-left shunting and hypoxia, for which the patient underwent a percutaneous repair of the atrial septal defect with immediate recovery of oxygen saturation.
