Endocardial pacing through a prosthetic tricuspid valve
1Department of Cardiology, Victoria Hospital, Blackpool, England.
Pacing and Clinical Electrophysiology : PACE
|November 1, 1990
Summary
Permanent endocardial pacing was achieved by guiding the electrode through a porcine bioprosthetic tricuspid valve, avoiding a second surgery. The patient maintained good pacing and valve function for 8 years.
Area of Science:
- Cardiology
- Cardiac Surgery
- Biomedical Engineering
Background:
- Permanent endocardial pacing is a common procedure for managing bradyarrhythmias.
- Tricuspid valve disease or prior surgery can complicate pacemaker implantation.
- Porcine bioprosthetic valves are used in cardiac valve replacement surgery.
Observation:
- A patient required permanent endocardial pacing.
- The patient had a previously implanted porcine bioprosthetic tricuspid valve.
- Standard transvenous lead placement was considered challenging.
Findings:
- Successful permanent endocardial pacing was achieved by navigating the pacing electrode through the porcine bioprosthetic tricuspid valve.
- This approach eliminated the need for a repeat thoracotomy.
- At 8-year follow-up, the patient demonstrated sustained satisfactory pacing and bioprosthetic valve function.
Implications:
- This technique offers a viable alternative for pacemaker implantation in patients with prosthetic tricuspid valves.
- It potentially reduces surgical morbidity by avoiding additional thoracotomies.
- Long-term efficacy of pacing through bioprosthetic valves is demonstrated.
