BACKGROUND: Transcatheter edge-to-edge mitral valve repair (M-TEER) using the MitraClip system is primarily performed using the transfemoral approach. However, when this approach is not feasible, the transjugular approach can be used as an alternative.
CASE SUMMARY: A 57-year-old man presented with heart failure and persistent New York Heart Association class IV symptoms, refractory to guideline-directed medical therapy, intravenous therapy, and intra-aortic balloon pumping. His medical history included pulmonary embolism secondary to deep vein thrombosis, which occluded the inferior vena cava (IVC). Transthoracic echocardiography (TTE) revealed severe functional mitral regurgitation (FMR). The IVC occlusion made the transfemoral approach impossible; hence, transjugular M-TEER was planned. Transseptal puncture was performed via the right internal jugular (RIJ), 32 mm above the mitral annulus. A Confida wire was positioned in the left ventricle, and a steerable guiding catheter was introduced with 180° clockwise rotation of the +knob for septal crossing through the stiff wire. The MitraClip XTW was inserted into the catheter with a 90° counterclockwise rotation. After adjusting to a straddle position to move the clip laterally, additional knob rotations were performed to position the clip at A2/P2. Once the clip was placed, only trivial mitral regurgitation (MR) remained. No complications occurred, and the patient improved, allowing discharge. Transthoracic echocardiography at 1-year post-procedure demonstrated sustained MR reduction.
DISCUSSION: We have described the successful completion of M-TEER using the RIJ approach in a patient with severe FMR. Technical considerations in M-TEER require special attention because of limited reports on the M-TEER procedure via the RIJ.
