case_images: A preoperative chest radiograph of the patient was depicted in Figure 1.
case_images: The LV lead was implanted into the LVFW along a sureValve 6250VIS under the guidance of CARTO 3 and x-ray imaging. (A) The CS lead was maneuvered into the LVFW through the mitral valve under the guidance of CARTO 3 and the potential of the CS lead. The potential of the CS lead pointing toward the LVFW is shown in the red box. (B) The CS lead which inserted into the Attain Command + SureValve 6250VIS passed through the centre of FO via the axillary vein followed by under 3D mapping and x-ray system. (C) Along the CS lead, SureValve 6250VIS was placed toward the LVFW. The LV lead was placed along the SureValve 6250VIS and rotated into LVFW. The red arrow shows the potential of the CS lead; the yellow box shows the potential at the center of the FO; the blue box shows the potential at the edge of the FO; LV: left ventricular; LVFW: left ventricular free wall; CS: coronary sinus; FO: fossa ovalis.

case_images: Based on those points, we moved the catheter up and down and left and right; furthermore, we noted the atrial signals and determined the centre (blue point) of the FO (Figure 2A). The electrical amplitude at the central FO was significantly lower than the FO border (Figure 2A). Merit Medical Systems, Inc., South Jordan, USA) followed by the Left-heart Delivery System (Attain Command + SureValve 6250VIS, Medtronic, Inc. Minneapolis USA) under 3D mapping and an x-ray system (Figure 2B). Medtronic, Inc. Minneapolis USA) was placed along the SureValve 6250VIS and rotated into the myocardium (Figure 2C).
case_images: (A) The LV lead was placed to LVFW under x-ray guidance. (B) Postoperative ECG of patients. The red arrows indicate the pacing rhythm. ECG: electrocardiograph.

case_images: Finally, the SureValve 6,250 VIS was torn off, the lead was connected to pacemaker, and the wound was stitched. x-ray images were illustrated in Figure 3A. Postoperative ECG was depicted in Figure 3B.
