Mitral transcatheter edge-to-edge repair via left internal jugular vein access successfully reduced mitral regurgitation from severe to mild without complications.
Case Report (n=1)
Left internal jugular vein access is a feasible alternative route for mitral transcatheter edge-to-edge repair in patients with complex venous anatomy precluding standard transfemoral or right internal jugular access.
BACKGROUND: The increasing indications of transcatheter edge-to-edge repair (TEER) have led to its use in more diverse populations, including patients with complex comorbidities where standard transfemoral access may not be feasible. In these cases, utilizing the right internal jugular vein (IJV) access has been reported as a safe and practical alternative route. Herein, we report the first case of mitral TEER via left IJV access, using PASCAL system. CASE PRESENTATION: A 50-year-old woman with long-standing chronic kidney disease and two previously failed renal transplants suffered repeated admissions for acute pulmonary edema. Echocardiography confirmed severe functional mitral regurgitation (MR) and global left ventricular systolic dysfunction. Due to extremely high surgical risk, the multidisciplinary heart team opted for mitral TEER. Unexpectedly, pre-procedural imaging demonstrated complete occlusion of the inferior vena cava with prominent collateral circulation and total occlusion of the right IJV. After extensive team discussion, access via the left IJV was selected. Transseptal puncture (TSP) was performed with the VersaCross radiofrequency system, the septum was dilated using a 6 mm Mustang balloon, and a PASCAL P10 device was successfully implanted between the A2 and P2 segments, resulting in reduction of MR severity from severe (4+) to mild (1+). The procedure concluded without complications and hemostasis was secured. At 2-month follow-up the patient remained stable with no recurrent decompensations. CONCLUSION: Left IJV is a feasible alternative access for mitral-TEER when other venous accesses are not feasible. Proper pre-procedural planning and local expertise is essential to overcome the technical challenges related to TSP and steering the guiding catheter against the complex anatomical orientation of the left innominate vein.
