A 6-French pigtail catheter was inserted into the right pulmonary artery, and angiography was performed (Fig. 2a). The coil seemed unstable on fluoroscopy, with a high mobility for several seconds, and then stabilized by adhering to the leaflets of the mitral valve (Fig. 2b).
34-year-old woman with a known arteriovenous pulmonary malformation (PAVM). Snare loop device placed at the level of the aortic valve via a femoral artery approach in order to remove the coil after dislodging it from the mitral apparatus.

With gentle taps on the proximal end of the coil, the distal end moved up to the aortic valve, where it was suitable for a safe removal with a 25-mm Amplatz Goose Neck snare (EV3, Plymouth, MN, USA), using the same guiding catheter (Fig. 3).
