Key result
Left-sided CIED implantation is linked to nearly 3-fold higher early venous stenosis or occlusion vs. right-sided.
Why the study?
There is little information on venous patency during the immediate postoperative period after permanent pacemaker or ICD implantation.
Does left-sided implantation or ICD implantation increase venous stenosis or occlusion compared to right-sided or pacemaker implantation in patients undergoing device implantation?
Population
25 patients undergoing permanent pacemaker or ICD implantation by venous puncture method
Comparison
Left-sided implantation vs right-sided implantation; ICD implantation vs pacemaker implantation
Design
Observational study
Follow-up
1 week

Acute venous changes post-implant may warrant early symptom vigilance; small observational series leaves open need for prospective confirmation.

Does left-sided implantation or ICD implantation increase venous stenosis or occlusion compared to right-sided or pacemaker implantation in patients undergoing device implantation?
Absolute Event Rate: 71% vs 25%
p-value: p=<0.05
Venous stenosis or occlusion is a frequent early complication within 1 week of pacemaker or ICD implantation, particularly associated with left-sided approaches and ICD devices.
Nakae et al. (2010) conducted an observational in Permanent pacemaker or ICD implantation (n=25). Left-sided device implantation vs. Right-sided device implantation was evaluated on Venous stenosis and occlusion (p=<0.05). Venous stenosis or occlusion occurred in 56% of patients 1 week post-implantation, with significantly higher rates for left-sided versus right-sided implantation (71% vs. 25%, P<0.05).
