Case description : A 74-year-old man suffering from severe heart failure (NYHA III – LVEF 28%) associated with left bundle branch block (LBBB) (Figure 1(A)) and uncontrolled permanent atrial fibrillation (AF) despite optimal medical treatment was referred for His ablation and rescue physiological pacing after a first unsuccessful LV lead implantation through the coronary sinus (CS). Careful review of the occluded CS angiogram indeed revealed no side branches. Concordantly, the patient was offered a ‘rescue’ HBP procedure. Using the SelectSecure lead (model 3830) and a C315 His sheath (Both Medtronic, Inc. MN), His mapping (HV ¼ 106ms) and recruitment were easily obtained, unfortunately without LBBB correction.
