Why the study?
Transvenous leads in cardiac pacing are susceptible to degradation and life-threatening infection, while dominant right ventricular pacing can cause left ventricular dysfunction.
The text introduces the rationale for a totally leadless biventricular pacing approach to avoid the complications associated with transvenous leads, such as degradation, infection, and pacing-induced left ventricular dysfunction.
May support leadless BiV pacing to avoid transvenous risks in select patients; leaves open need for prospective validation.
The major weakness of transvenous cardiac pacing derives from the fact that energy is delivered to the heart muscle from the pacing device through transvenous lead (TL). The TL has been shown to be susceptible to degradation over time, and in the case of infection the event may be life-threatening. Dominant right ventricular (RV) pacing may also lead to left ventricular (LV) dysfunction.
