Authors' conclusion

Effective management of TVL-associated SVC syndrome involves venoplasty with or without transvenous lead extraction, showing good medium-term outcomes. Reimplantation of the device with TVL requires careful consideration, and efforts should be made to consider a leadless device when feasible.
