Aortosubpulmonary Fistula after Konno-Rastan Aortoventriculoplasty.

• Degeneration of a Konno patch can result in a complicated aortic pseudoaneurysm. • Multimodality imaging was required for diagnosis and intraoperative management. • Peripheral cardiopulmonary bypass and retroplegic cardiac arrestprior to sternotomy can prevent fatal hemorrhage. • An endovascular aortic occlusion device can be used to “clamp” the aorta. • Multimodal imaging and a multidisciplinary team were required for optimal results.
