Elevated Defibrillation Threshold When Right‐Sided Venous Access is Used for Nonthoracotomy Implantable Defibrillator Lead Implantation
Why the study?
Does right-sided venous access increase the defibrillation threshold compared to left-sided access in patients undergoing ICD implantation?

Implication
Right-sided access was associated with higher thresholds; hypothesis-generating and should not yet change practice.
Structured PICO
Does right-sided venous access increase the defibrillation threshold compared to left-sided access in patients undergoing ICD implantation?
P
Population
345 patients undergoing transvenous implantable cardioverter defibrillator lead implantation with two defibrillating coils, mean age 61 +/- 13 years, LVEF 0.33 +/- 0.13.
I
Intervention
Right-sided venous access for transvenous implantable cardioverter defibrillator lead implantation
C
Comparator
Left-sided venous access
O
Outcome
Biphasic defibrillation thresholdsurrogate
Left-sided venous access for ICD lead implantation results in lower defibrillation thresholds compared to right-sided access, particularly when used without a subcutaneous patch.
