Abstract
We present the case of a 60yearold woman with symptomatic mitral regurgitation caused by a lefttoright shunt via anastomoses consisting of microfistulae most likely of inflammatory origin between the right subclavian artery and the right pulmonary artery The three arteries responsible for fistulous formation including the internal mammary thyrocervical and lateral thoracic arteries were successfully occluded by transcatheter embolization using superabsorbent polymer microsphere SAPMS particles combined with metallic coils No complications have been identified following treatment with SAPMS particles This approach significantly reduced the patient’s mitral regurgitation and she has remained asymptomatic for more than 4 years
