Literature was reviewed regarding clinical outcomes of permanent left bundle branch area pacing (lbbap).The authors described patient deaths; the causes of death included death from any cause or for progressive heart failure (hf).One patient with lvef lower than 25% was noted to have passed soon after left ventricular septal pacing (lvsp) due to ventricular fibrillation (vf).There is no allegation of lead-death relatedness indicated in the article; however, the lead-relatedness has been requested, but not yet received.There were patients who experienced pocket infections and underwent incision and drainage of the device pocket and patients who experienced heart failure hospitalizations.The status of the leads is unknown.No additional adverse patient effects were reported.
