Summary
Total endoscopic aortic valve replacement (TE-AVR) offers a less invasive approach compared to traditional sternotomy. While requiring longer bypass times, TE-AVR leads to reduced ventilation and shorter hospital stays, indicating quicker recovery.
Area of Science:
- Cardiovascular Surgery
- Minimally Invasive Procedures
- Aortic Valve Replacement
Background:
- Traditional aortic valve replacement (AVR) involves a full sternotomy, a major surgical incision.
- Minimally invasive techniques aim to reduce surgical trauma and improve patient recovery.
- Total endoscopic AVR (TE-AVR) utilizes small ports for valve replacement, avoiding a large chest incision.
Purpose of the Study:
- To detail the technical aspects of total endoscopic aortic valve replacement (TE-AVR) using standard prostheses.
- To compare the clinical outcomes and safety of TE-AVR versus traditional full-sternotomy AVR.
Main Methods:
- A comparative study involving 60 patients undergoing elective isolated AVR from 2020-2021.
- Patients were divided into two groups: TE-AVR (29 patients) and traditional AVR (31 patients).
- The TE-AVR procedure was performed using three working ports.
Main Results:
- No mortality occurred in either group.
- TE-AVR group had longer cardiopulmonary bypass (CPB) and aortic cross-clamp (ACC) times (p < 0.001 for both).
- TE-AVR patients experienced shorter mechanical ventilation duration (p=0.015) and hospital stays (p=0.025).
Conclusions:
- Total endoscopic aortic valve replacement is a safe and feasible procedure.
- TE-AVR is associated with reduced trauma and a faster patient recovery.
- Further research may explore optimizing CPB and ACC times in TE-AVR.
