May warrant vigilance for late SVC syndrome after transvenous pacing; leaves open true incidence and prevention strategies.
Case Report (n=1)
This case highlights that superior vena cava syndrome, though rare, can occur as a late complication of transvenous permanent pacemaker implantation and may be well-tolerated if adequate collateral circulation develops.
Lin et al. (1999) conducted a case report in High grade AV block / Superior vena cava syndrome (n=1). Transvenous permanent pacemaker implantation was evaluated on Superior vena cava syndrome. Transvenous permanent pacemaker implantation resulted in superior vena cava syndrome due to fibrotic stenosis and extensive thrombus formation 2 years post-procedure in a patient with AV block.
