Does percutaneous double balloon pulmonary valvotomy reduce peak systolic transvalvar pressure gradient in adults with congenital pulmonary valve stenosis?
Percutaneous double balloon pulmonary valvotomy is an effective treatment for isolated pulmonary valve stenosis in adults, significantly reducing transvalvar pressure gradients while maintaining heart rate and systemic pressure during inflation.
Kasab et al. (1987) studied this question.
