The Fate of Aortic Valve After SAS Surgery in Children

Aortic Valve Regurgitation After Surgical Repair for Subaortic Stenosis in Children

Aortic valve regurgitation (AR) is a common complication following surgery for subaortic stenosis (SAS), yet the long-term outcomes and risk factors for postoperative significant AR (SAR) remain poorly understood. This study aims to investigate the incidence and risk factors of SAR in SAS patients and evaluate the long-term postoperative outcomes.

Inclusion Criteria:

• Age from 0-18
• Clinical diagnosis of subaortic stenosis and underwent surgery

Exclusion Criteria:

• Diagnosed with hypertrophic cardiomyopathy
• Underwent concomitant previous surgical repair for aortic valve or SAS
• Follow-up time less than 1 year or lack of detailed information.
