Percutaneous Transcatheter Closure Of A Fistula Between Aorta And Left Atrium By Amplatzer Septal Occluder In A Patient With A Biological Mitral Prosthesis

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.
