Pulmonary Arteriovenous Fistula Coexisting with Rheumatic Mitral Disease. Simultaneous Successful Correction under Cardiopulmonary Bypass in One Case. Review of the Literature

Summary

The authors report a rare case of coexistence of a pulmonary arteriovenous fistula with rheumatic mitral disease. The diagnosis was suspected clinically and with the chest X-ray, and was confirmed by the cardiac catheterization showing mitral disease and a pulmonary arteriovenous fistula with arterial desaturation (70%). Successful surgery (aneurysmal excision and closure of abnormal communication together with mitral valve repair) was undergone under cardiopulmonary bypass. In the literature, 7 cases of this association have been reported, with surgery in 4. None of the cases had a procedure similar to the above-mentioned and simultaneous surgery was not recommended.

The authors show that the anatomic situation of the case reported allowed simultaneous surgery, and that cardiopulmonary bypass rendered the procedure easy.
