Key result
Left bundle branch area pacing can lead to a rare complication of dry tamponade caused by interventricular septal hematoma, requiring temporary mechanical circulatory support.
Why the study?
Left bundle branch area pacing has shown clinical advantages over traditional pacing, but carries unique procedure-related complications due to its implantation technique.
Case Report (n=1)
Highlights a rare but severe complication (dry tamponade from septal hematoma) associated with left bundle branch area pacing that may require mechanical circulatory support.
Case of LBBAP complication raises procedural vigilance; leaves open long-term safety questions versus conventional pacing.
Left bundle branch area pacing (LBBAP), a form of the specific stimulation of the cardiac conduction system, has been increasingly adopted for pacemaker therapy in recent years.1,2 LBBAP was reported to be advantageous concerning heart failure–related clinical endpoints when compared with both right ventricular pacing and classic biventricular pacing for several pacing indications.3–5 Although the overall rate of procedure-related adverse events is similar to other forms of cardiac pacing, LBBAP has some unique complications because of its implantation technique.

König et al. (2025) conducted a case report in Dry tamponade caused by interventricular septal hematoma (n=1). Left bundle branch area pacing (LBBAP) was evaluated. Left bundle branch area pacing can lead to a rare complication of dry tamponade caused by interventricular septal hematoma, requiring temporary mechanical circulatory support.
