Summary

Early mobilization after aortic valve replacement (AVR) surgery is safe and feasible. This fast-track approach enhances patient recovery without serious adverse events, even in high-risk cardiac patients.

Area of Science:

  • Cardiac Surgery
  • Peri-operative Care
  • Patient Recovery

Background:

  • The paradigm in cardiac surgery recovery has shifted towards early patient mobilization and nutrition.
  • Evidence on the safety of early postoperative mobilization in high-risk groups, such as aortic valve replacement (AVR) patients, remains limited.
  • Previous studies on coronary artery bypass grafting (CABG) patients showed physiological changes during mobilization.

Purpose of the Study:

  • To assess the safety and feasibility of early postoperative mobilization in patients undergoing aortic valve replacement (AVR) surgery.
  • To evaluate the physiological responses and outcomes associated with early mobilization in AVR patients.

Main Methods:

  • Controlled studies were conducted on patients undergoing AVR.
  • Physiological parameters including heart rate, stroke volume, cardiac output, and oxygen consumption were monitored during mobilization.
  • A retrospective review of over 1200 AVR patients mobilized over 13 years was performed.

Main Results:

  • Mobilization in AVR patients led to increased heart rate and decreased stroke volume, with maintained cardiac output.
  • Oxygen consumption increased by 50-60%, met by increased oxygen extraction, causing mixed venous oxygen desaturation.
  • No serious side effects were observed in controlled trials or during the 13-year mobilization of over 1200 AVR patients.

Conclusions:

  • Early postoperative mobilization is a safe and viable strategy for patients following aortic valve replacement (AVR) surgery.
  • This fast-track approach can be implemented without significant adverse events, supporting enhanced patient recovery.
  • The findings support the integration of early mobilization into standard peri-operative care for AVR patients.
