Device embolisation after transcatheter paravalvular leak closure

Ignacio Cruz-Gonzalez*, MD, PhD; Jose A. Perez-Rivera, MD, PhD; Antonio Arribas-Jimenez, MD, PhD; Javier Rodríguez-Collado, MD; Pedro L. Sanchez, MD, PhD

An Amplatzer Vascular Plug III 14×5 mm (St. Jude Medical, St. Paul, MN, USA) device was deployed in a 65-year-old man with severe mitral paravalvular regurgitation. The distal disc of the device was deployed inside the paravalvular leak tunnel between the left ventricle and left atrium to prevent interference with the monodisc prosthesis (Appendix Figure 1). At three-month transoesophageal echocardiography (TEE) mild mitral regurgitation was observed, the atrial disc of the device seemed not to be totally apposed to the leak and it was protruding into the left atrium (Figure 1, Moving image 1). At six-month TEE a moderate regurgitation was observed because both discs of the device had moved into the left atrium (Figure 1, Moving image 2).

Due to the risk of embolisation the patient was brought to the catheterisation laboratory seven days after the TEE and the device had already embolised to the left iliac artery (Appendix Figure 1). It was snared from the tip and was removed successfully.

Late embolisation is an extremely rare complication. Spontaneous late embolisation has not been described before. Routine echocardiographic follow-up can detect this potential complication.
