Right ventricular outflow tract obstruction natural history
The Natural History of Right Ventricular Outflow Obstruction
Among patients with moderate to severe pulmonic stenosis (PS), the gradients often increases or is progressive. In patients with mild PS the gradient often remains stable. The prognosis among patients with PS who have reached adulthood without right ventricular failure or symptoms is reported to be good with minimal risk of endocarditis, RV failure or death.
