Chiusura percutanea transcatetere di una fistola tra aorta e atrio sinistro mediante occlusore settale Amplatzer in un paziente con protesi mitralica biologica [Percutaneous transcatheter closure of an aorta to left atrium fistula with an Amplatzer septal occluder in a patient with a mitral bioprosthesis]

We describe the case of a patient with a mitral bioprosthetic valve undergoing percutaneous closure with fluoroscopy and echocardiographic guidance of a rare left sinus of Valsalva left atrial fistula. The original aspect of this case is that the fistula was located at the level of the left sinus of Valsalva next to the mitral valve bioprosthesis with subsequent risk of prosthesis damage and/or occlusion of the left coronary artery at its origin during the procedure.
