简介：
Overview
This manuscript reviews the indications, management, and outcomes for the total artificial heart (TAH). It also presents video operative techniques for device implantation.
Key Study Components
Area of Science
- Cardiac surgery
- Heart failure management
- Artificial heart technology
Background
- The TAH is used as a bridge to transplantation for patients with severe biventricular failure.
- It provides high flow biventricular support compared to left ventricular assist devices.
- The SynCardia TAH is the only FDA-approved total artificial heart in clinical use.
- Implantation techniques are critical for successful outcomes.
Purpose of Study
- To review the indications for TAH implantation.
- To discuss management strategies for patients receiving TAH.
- To evaluate outcomes associated with TAH use.
Methods Used
- Operative techniques for TAH implantation are described.
- Preoperative assessments include echocardiography and hemodynamic testing.
- Device preparation involves sealing grafts and ensuring proper surgical technique.
- Postoperative care focuses on rehabilitation and monitoring for transplantation.
Main Results
- The TAH effectively restores cardiac output in patients with biventricular failure.
- Patients are aggressively rehabilitated while awaiting transplantation.
- Successful implantation requires meticulous surgical technique to minimize complications.
- TAH offers advantages over isolated left ventricular support in complex cases.
Conclusions
- TAH serves as a critical option for patients with severe heart failure.
- Proper management and surgical techniques are essential for optimal outcomes.
- Further studies are needed to refine indications and improve patient selection.
What is the total artificial heart?
The total artificial heart (TAH) is a device implanted to replace the function of a failing heart.
Who is a candidate for TAH implantation?
Candidates typically have severe biventricular failure and may not be suitable for isolated left ventricular assist devices.
What are the main advantages of TAH over other devices?
TAH provides high flow support for both ventricles and can address complex cardiac pathologies.
How is the TAH implanted?
Implantation involves surgical techniques to secure the device and maintain the pericardial space.
What is the expected outcome after TAH implantation?
Patients typically experience restored cardiac output and improved organ perfusion while awaiting transplantation.
Is the TAH FDA approved?
Yes, the SynCardia TAH is the only FDA-approved total artificial heart currently in use.
What is the role of rehabilitation after TAH implantation?
Rehabilitation is crucial for recovery and preparing patients for potential heart transplantation.
