Infundibular Stenosis of the Heart

Infundibular Stenosis of the Heart is a condition where the pathway from the heart’s right ventricle to the pulmonary artery narrows. This narrowing, or stenosis, can hinder the smooth flow of blood, affecting the heart’s ability to pump effectively. In this comprehensive guide, we’ll break down the types, causes, symptoms, diagnostic tests, treatments, drugs, and surgical options related to Infundibular Stenosis of the Heart in simple, plain English.

Types of Infundibular Stenosis:

Infundibular Stenosis can be categorized into two main types:

1. Valvular Infundibular Stenosis: Involves the narrowing of the pulmonary valve, impeding blood flow from the right ventricle to the pulmonary artery.
2. Subvalvular Infundibular Stenosis: Refers to narrowing below the pulmonary valve, obstructing the passage between the right ventricle and the pulmonary artery.
