Aortic Valve-Sparing Root Replacement (David I Procedure) in Adolescents: Long-Term Outcome

Area of Science:

• Cardiovascular Surgery
• Pediatric Cardiology
• Aortic Root Surgery

Background:

• Aortic valve-sparing root replacement (David's procedure) is a preferred surgical option for young patients with aortic root pathology.
• Adolescent patients with aortic conditions require specific considerations for surgical interventions.

Purpose of the Study:

• To evaluate the short-, mid-, and long-term outcomes of the David-I procedure in adolescent patients.
• To assess the safety and efficacy of aortic valve-sparing root replacement in a young population.

Main Methods:

• Retrospective study of 29 adolescent patients (aged 6-21 years) who underwent the David-I procedure between 1994 and 2014.
• Comprehensive follow-up data analysis, including survival and reoperation rates, over a mean period of 13.6 years.

Main Results:

• The study reported no early perioperative deaths. Long-term survival estimates at 1, 5, and 10 years were 100%, 97%, and 93%, respectively.
• Freedom from valve-related reoperation at 1, 5, and 10 years was 100%, 86%, and 83%. Four late deaths (14%) and five reoperations (17%) occurred during follow-up.
• Perioperative mortality for reoperations was 0%.

Conclusions:

• Aortic valve-sparing root replacement in adolescents is associated with very low perioperative risk.
• Long-term survival following this procedure in adolescents may be impacted by underlying connective tissue diseases, such as Marfan syndrome.
