Pulmonary Valve Stenosis

  • Pulmonary valve stenosis

     Pulmonary valve stenosis is a condition characterized by obstruction to blood flow from the right ventricle to the pulmonary artery. This obstruction is caused by narrowing (stenosis) at one or more points from the right ventricle to the pulmonary artery. The most common form of pulmonary stenosis is obstruction at the valve itself, referred to as pulmonary valvar stenosis.

  • Pulmonary valve stenosis

    Pulmonary valve stenosis signs and symptoms vary, depending on the extent of the obstruction. People with mild pulmonary stenosis usually don't have symptoms. Pulmonary valve stenosis signs and symptoms may include Heart murmur - an abnormal whooshing sound heard using a stethoscope, caused by turbulent blood flow, Shortness of breath, especially during exertion, Chest pain, Loss of consciousness (fainting), Fatigue.

  • Pulmonary valve stenosis

    Patients with mild pulmonary valve stenosis are healthy, can participate in all types of physical activities and sporting events, and lead normal lives. The type of treatment required depends on the type of valve abnormality present. Statistical Analysis of pulmonary valve stenosis in India got the results as the median age was 36.5 months (3-444 months). There were no deaths. Pulmonary regurgitation was mild in 18, moderate in 10, and severe in 2 patients immediately following surgery. At 1 year, 10 patients had severe PR and one had significant RVOT gradient. None of the variables like age, presence of supravalvar pulmonary branch stenosis, main pulmonary artery diameter, or mobility of monocusp valve was found to have any significant association with the progression of PR. McGoon index <1.5 showed a trend toward more PR, while patients with more residual RVOT gradient had lesser regurgitation.
