valvotomy
Pronunciation: val-VOT-oh-mee
Surgical procedure involving incision or division of valve leaflets to relieve stenosis, commonly performed on pulmonary or aortic valves in pediatric patients.
Full Definition
Valvotomy is a surgical technique used to treat valvular stenosis by making precise incisions in the valve commissures or leaflets to improve valve opening. In pediatric cardiology, this procedure is most commonly performed for pulmonary valve stenosis and aortic valve stenosis in neonates and infants. The goal is to increase the effective valve orifice while preserving as much valve function as possible to avoid significant regurgitation. Pulmonary valvotomy can often be performed through a limited right ventriculotomy, while aortic valvotomy may require more complex approaches. While effective for relieving stenosis, the procedure may result in some degree of valve regurgitation, and patients typically require lifelong follow-up to monitor valve function and potential need for future intervention.
Usage
Usage note: Specify valve involved and surgical approach; distinguish from catheter-based balloon valvuloplasty.
