Acquired aortopulmonary fistula is a rare condition that may cause heart failure symptoms secondary to high-output pulmonary overload. We report an unusual case of an aortopulmonary fistula secondary to an aortic injury sustained during mitral valve replacement, which was identified during follow-up because of recurrent heart failure symptoms and repeated hospital admissions. Multimodality imaging allowed precise characterization of the fistula. After a Heart Team discussion, percutaneous closure was selected as the preferred treatment strategy. Based on the assessment of the fistula's trajectory and morphology, a Patent Ductus Arteriosus (PDA) occluder was selected. Although the fistula's ostium was difficult to identify, successful closure was achieved using the PDA occluder.
