Minimally invasive valve sparing aortic root replacement (David procedure) is safe.

Area of Science:

• Cardiovascular Surgery
• Minimally Invasive Cardiac Procedures
• Aortic Root Reconstruction

Background:

• Minimally invasive cardiac surgery offers potential morbidity benefits but isn't standard for aortic root replacement.
• Aortic root replacement is a complex procedure typically performed via full sternotomy.

Purpose of the Study:

• To evaluate the safety and feasibility of valve sparing aortic root replacement using an upper mini-sternotomy approach.
• To compare outcomes of minimally invasive aortic root replacement with the traditional full sternotomy method.

Main Methods:

• A pilot study compared 26 patients undergoing minimally invasive valve sparing aortic root replacement (David procedure) with 14 patients undergoing the same procedure via full sternotomy.
• Data collected included operative times, need for conversion, re-operations, post-operative recovery, and 30-day mortality.

Main Results:

• No intra-operative conversions to full sternotomy were required in the minimally invasive group.
• Post-operative outcomes, including ventilation time and hospital stay, were comparable between groups, with no 30-day mortality in either.
• The minimally invasive approach resulted in an approximate two-week convalescence period.

Conclusions:

• Minimally invasive valve sparing aortic root replacement is a safe and feasible option for carefully selected patients.
• Outcomes are comparable to those achieved with full sternotomy, with potential for quicker recovery.
• A stepwise approach, meticulous hemostasis, and attention to surgical detail are crucial for success.
