Residual or recurrent obstruction after septal myectomy in young children and infants with hypertrophic cardiomyopathy: cohort study.

ABSTRACT:

Background

The outcomes after septal myectomy in young children and infants with hypertrophic obstructive cardiomyopathy (HOCM) are not clear. The study sought to report the outcomes after septal myectomy in young children and infants and identify the mechanisms of residual or recurrent obstruction after surgery.

Methods

The authors performed an observational cohort study of children and infants under the age of 14 who underwent septal myectomy for HCOM from January 2013 to December 2020. Mean follow-up among 94.3% ( n =50) of hospital survivors was 42.09±24.38 months.

Results

In total, 56 children and infants [mean (SD) age, 5.38 (3.78) years; 29 (58.1%) were male] underwent septal myectomy for HOCM. Cumulative survival was 100, 96.6, 93.0, and 81.4% at 1, 3, 5, and
