Twenty-five year outcomes following composite graft aortic root replacement

Area of Science:

• Cardiovascular Surgery
• Aortic Root Disease Management
• Surgical Outcomes Research

Background:

• Aortic root disease necessitates surgical intervention, with options including traditional root replacement and valve-sparing procedures.
• Composite graft aortic root replacement is a key surgical technique for managing complex aortic root pathologies.

Purpose of the Study:

• To evaluate the long-term outcomes of traditional composite graft aortic root replacement.
• To assess survival rates and freedom from reoperation and adverse events after this procedure over 25 years in 449 patients.

Main Methods:

• A single-surgeon series of 449 patients undergoing composite graft aortic root replacement using the coronary button technique.
• Data collected included patient demographics, prosthesis type, concomitant procedures, and operative urgency.
• Long-term follow-up assessed survival, reoperation, and major adverse events.

Main Results:

• Operative mortality was 3.1%, with low rates of stroke (2.0%) and re-exploration for bleeding (4.5%).
• Long-term freedom from major events and reoperations was high, exceeding 94% at 20 years.
• Survival rates were comparable to age- and gender-matched controls, particularly in younger patients.

Conclusions:

• Composite graft aortic root replacement demonstrates a low operative risk profile.
• The procedure is associated with excellent long-term survival and a low incidence of late reoperations and adverse events.
• This technique remains a safe and effective option for aortic root disease management.
