The patient was taken to the cardiac catheterization lab for a transarterial aortic valve replacement (tavr).After placement of the aortic valve, post echocardiography with transesophageal echocardiography (tee) showed trace paravalvar regurgitation.The valve had a constricted appearance on fluoroscopy and the mean gradient across the valve measured at 17 mmhg.The procedure felt that this was too high of a gradient to leave and elected to proceed with balloon valvuloplasty. a 20 mm true balloon was used to dilate the valve.The balloon was taken to high pressure but ruptured during inflation.Unfortunately, there was significant resistance in retrieving the balloon back into the 14 fr sheath.The team attempted to bring the entire system out as a unit thinking that the balloon was not retrievable from the artery.With significant retraction on the system the balloon dissociated from the balloon catheter and became lodged in the external iliac artery. several maneuvers were attempted to remove the balloon including upsizing to a 16fr sheath and snaring from the ipsilateral side and retrieval with a bioptome.Unfortunately the material appeared to be compressed in the external iliac artery and we could not retrieve it. a dsa was taken of the iliac system showing occlusion of the external iliac artery. the vascular surgery service was consulted.After discussions of potential options, the teams felt that surgical extraction of balloon material was going to be better option.The vascular surgeon performed surgical extraction of balloon material.
