Trial Title: Ultrasound-guided Venous Access for Pacemaker and Defibrillator Implants

Study Design Characteristics:
- Allocation: RANDOMIZED
- Intervention Model: PARALLEL
- Observational Model: None
- Primary Purpose: TREATMENT
- Time Perspective: None
- Masking: NONE
- Phase: None
- Number of Arms: 2.0

Eligibility Criteria:
Inclusion Criteria:~* Planned pacemaker or implantable defibrillator surgery with at least one new transvenously placed lead.~Exclusion Criteria:~* Difficult vascular access known before surgery, where special access technique is planned or required.

- Gender: ALL
- Minimum Age: 18 Years
- Maximum Age: None
- Healthy Volunteers: f

Study Arms:
- Ultrasound guided venous access (Type: EXPERIMENTAL): Vascular access of the axillary vein will be performed using an ultrasound system (Siemens Acuson Freestyle) with a wireless vascular ultrasound probe (L8-3 or L13-5). One or more vascular punctures will be performed, as needed.
- Standard of care (Type: NO_INTERVENTION): Vascular access of the axillary or subclavian vein will be performed using anatomical landmarks, fluoroscopy and/or injection of X-ray contrast in the antecubital vein, at the choice of the implanter. One or more vascular punctures will be performed, as needed.

Based on this trial design, predict the completion outcome and termination type (if applicable).
