Challenging a dogma: left ventriculotomy can be used safely in children

Abstract

Objective: We aimed to discuss our unit's experience performing left ventriculotomies on children.

Methods: Between 2000 and 2022, we identified paediatric patients who required left ventriculotomy. Relevant information was gathered retrospectively.

Results: There were eight patients who underwent surgical procedure including left ventriculotomy. The range of weight and age was between 4.5 and 50 kg and 5 months to 17 years, respectively. Left ventriculotomy was primarily performed for the excision of cardiac masses in all but one who had pseudoaneurysm repair. There were no deaths that occurred early or late. Pre-operative and post-operative ejection fractions and fractional shortening values were comparable. There was no arrhythmia detected post-operatively.

Conclusions: We conclude that an apical left ventriculotomy does not compromise the function of the left ventricle, even in young infants. In selected patients, it may be used safely for surgical access to the left ventricle.
