Clinical Information

Patient initials or Identifier Number

Relevant Clinical History and Physical Exam

84-year-old female with symptomatic severe functional mitral regurgitation (MR) due to long standing atrial fibrillation underwent transcatheter edge-to-edge repair using the MitraClip system. After deployment of an XTR clip in the A2-P2segment, a second MitraClip XT device was deployed laterally to prevent recurrence of MR due to stretching of left atrium and mitral leaflets. However, single leaflet detachment of the anteriorleaflet occurred immediately.

Relevant Test Results Prior to Catheterization

Since only mild MR was observed after theprocedure, additional clipping was not performed. However, at two weeks after discharge, the patientpresented with right inguinal pain and aggravated symptoms of dyspnea.Thelateral clip was not observed on chest x-ray. Computed tomography revealed themigrated MitraClip at the bifurcation of right common iliac artery. Transesophagealechocardiography (TEE) showed recurrence of severe MR with small chordae rupture.


Relevant Catheterization Findings

Peripheral angiography revealed embolized clip at Rt common iliac artery bifurcation site.

Interventional Management

Procedural Step

The embolized MitraClip was successfully retrieved using 10mm and 15mm Amplatz GooseNeck¢ç snares (Ev3, Plymouth, MN, USA) through a 16-French Check-Flo¢ç Introducer sheath (Cook Medical, Bloomington, IN, USA),and another NTW clip was successfully deployed. Post-procedure TEE confirmed residual mild to moderate MR. Images from this case show the complications of MitraClip single leaflet detachment and distal migration to lower-extremityartery, and how this problem was successfully solved by intervention.


Case Summary

MitraClip single-leaflet detachment and consequent migration in common iliac artery was succefully managed with percutaenous intervention with re-do MitraClip and retrieval of emolized clip with snares without any complications.
