Summary
Valve-sparing root replacement (VSRR) offers a durable solution for aortic root aneurysms. This study shows excellent early- and mid-term outcomes, with high freedom from mortality and reoperation after VSRR.
Area of Science:
- Cardiovascular Surgery
- Thoracic Surgery
- Aortic Surgery
Background:
- Traditional valve-replacing root replacement carries significant risks.
- Valve-sparing root replacement (VSRR) is an alternative surgical technique.
- Outcomes of VSRR require further investigation for long-term efficacy.
Purpose of the Study:
- To evaluate the early- and mid-term outcomes of valve-sparing root replacement.
- To assess the durability and safety of VSRR in patients with aortic root aneurysms.
Main Methods:
- Retrospective review of a prospectively maintained aortic registry.
- Inclusion of all patients undergoing VSRR between 2005 and 2023.
- Kaplan-Meier analysis for mortality, aortic insufficiency, and reoperation rates.
Main Results:
- Eighty-one patients underwent VSRR with no perioperative aortic insufficiency >1+.
- Excellent survival rates: 10-year freedom from all-cause mortality was 94.4%.
- High composite freedom from reoperation, recurrence, or mortality at 10 years was 87.3%.
Conclusions:
- Valve-sparing root replacement is a durable and safe procedure when patients are carefully selected.
- VSRR demonstrates favorable early- and mid-term results for aortic root aneurysm treatment.
- This technique preserves native valve function, potentially improving long-term patient outcomes.
