Summary
Thoracoscopic implantation of implantable cardioverter defibrillator (ICD) patches and leads is feasible. This minimally invasive technique yielded comparable results to open surgery in most patients, offering a potential alternative.
Area of Science:
- Minimally Invasive Cardiac Surgery
- Electrophysiology
- Medical Device Technology
Background:
- Traditional implantable cardioverter defibrillator (ICD) implantation requires sternotomy or thoracotomy.
- Development of thoracoscopic techniques offers a less invasive surgical approach.
- Evaluating the feasibility and efficacy of thoracoscopic ICD lead and patch implantation is crucial.
Observation:
- Thoracoscopic implantation of ICD patches and sensing leads was performed in three patients.
- Successful implantation was achieved in two patients without sternotomy or thoracotomy.
- One patient required conversion to thoracotomy due to difficulties in patch placement.
Findings:
- Defibrillation threshold (DFT), cardioversion energy requirement (CER), and signal quality were comparable to open techniques in successfully implanted patients.
- Titanium mesh defibrillator patches and screw-in epicardial sensing leads were applied effectively via thoracoscopy.
- The procedure demonstrated feasibility, with comparable electrophysiological parameters to conventional methods.
Implications:
- Thoracoscopic ICD implantation presents a viable, less invasive alternative to open procedures.
- This technique may reduce surgical trauma and recovery time for patients requiring ICDs.
- Further research and refinement of thoracoscopic techniques are warranted for broader clinical application.
