Current trends in minimally invasive valve-sparing aortic root replacement-Best available evidence

Area of Science:

• Cardiovascular Surgery
• Minimally Invasive Cardiac Surgery

Background:

• Valve-sparing aortic root replacement, specifically the reimplantation (David) procedure, is gaining popularity.
• Despite technical complexity, excellent long-term outcomes are achievable in selected patients.
• Minimally invasive approaches are increasingly favored for this procedure.

Purpose of the Study:

• To review literature on minimally invasive valve-sparing aortic root replacement (David procedure) via upper hemisternotomy.
• To assess current trends and potential advantages of this minimally invasive technique.

Main Methods:

• Literature review focusing on valve-sparing aortic root replacement (David procedure) using minimally invasive access.
• Analysis of patient selection, preoperative work-up, and surgical technique via upper ministernotomy.

Main Results:

• Nonrandomized studies show excellent clinical outcomes for minimally invasive David procedure in selected patients.
• Perioperative mortality and outcomes are comparable to conventional techniques.
• The procedure has been performed in carefully selected patients to date.

Conclusions:

• Minimally invasive David procedure demonstrates excellent clinical outcomes and comparable safety to conventional methods.
• This technique may offer faster recovery and improved cosmesis, especially for younger patients (e.g., Marfan syndrome, bicuspid aortic valve).
• Individualized patient selection and team experience are crucial; further randomized trials are needed to confirm long-term durability.
