Acquired aorto-pulmonary artery fistula following proximal aortic surgery.

A 56-year-old man developed left heart failure secondary to left to right shunt due to acquired aorto-pulmonary artery (PA) fistula. He had previously undergone aortic root replacement for streptococcal aortic valve endocarditis. A modified strategy involving interventional radiology and surgical technique was employed to deal with this complex surgical challenge. A balloon catheter was placed in the right PA to enable fistula occlusion during cardiopulmonary bypass followed by repair using cardiopulmonary bypass and circulatory arrest.
