The procedure involves deploying the lead deep inside the interventricular septum through left subclavian vein. We aimed at analyzing the feasibility, efficacy and long\u2010term outcome of left bundle branch pacing (LBBP) using lumen\u2010less lead through the right subclavian vein.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>This was a retrospective\u2010institutional, single center observational study done in consecutive patients who underwent LBBP using 3830 selectsecure<jats:sup>tm<\/jats:sup> lead. Left subclavian venous access was the primary strategy for lead implantation. Patients requiring right sided approach due to venous obstruction or persistent left superior\u2010vena\u2010cava (PLSVC) for LBBP were included in the study.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Right sided approach was successful in 16 out of 19\u2009(84%) attempted patients. C315\u2010His catheter was used in all patients without modifying its curvature. PLSVC\u00a0(<jats:italic>n<\/jats:italic>\u2009=\u20097), left venous obstruction (<jats:italic>n<\/jats:italic>\u2009=\u20097), right sided device upgradation (<jats:italic>n<\/jats:italic>\u2009=\u20091) and left pocket infection (<jats:italic>n<\/jats:italic>\u2009=\u20091) were the reasons for right sided approach. Mean follow\u2010up duration was 17\u2009\u00b1\u200912 months. LBBP resulted in reduction in QRS duration from 137.3\u2009\u00b1\u200937.8\u2009ms to 122.3\u2009\u00b1\u20099.5\u2009ms (<jats:italic>p<\/jats:italic>\u00a0\u2212.13) and increase in LV ejection fraction from 46.2\u2009\u00b1\u200916.3% to 54.4\u2009\u00b1\u200911.6% (<jats:italic>p<\/jats:italic>\u00a0\u2212.11). The mean fluoroscopy duration and radiation dose were significantly high in right sided approach (<jats:italic>n<\/jats:italic>\u2009=\u200916) as compared to left sided approach (<jats:italic>n<\/jats:italic>\u2009=\u2009293). In patients requiring cardiac\u2010resynchronization therapy (CRT), right sided LBBP resulted in reduction in QRS duration from 171.8\u2009\u00b1\u200918.5 to 125.5\u2009\u00b1\u200911.9\u2009ms (<jats:italic>p<\/jats:italic>\u00a0\u2212.0001) and increase in LVEF from 29.1\u2009\u00b1\u20093.8 to 45.1\u2009\u00b1\u200911.9% (<jats:italic>p<\/jats:italic>\u00a0\u2212.005).<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>Right sided LBBP is feasible, safe and effective in patients requiring pacing for symptomatic bradyarrhythmia and CRT.
