Pulmonary stenosis is a condition characterized by the narrowing of the pulmonary valve or artery, which obstructs blood flow from the right ventricle to the lungs. This can lead to increased right ventricular pressure and potentially result in right ventricular hypertrophy if left untreated.

Obstructed blood flow refers to the partial or complete blockage of blood vessels, which can lead to reduced oxygen and nutrient delivery to tissues and organs, potentially causing serious health complications. This condition can result from various factors such as atherosclerosis, blood clots, or external compression of vessels, and requires timely medical intervention to prevent damage.

Obstructed Blood Flow

The right ventricle is one of the four chambers of the heart, responsible for pumping deoxygenated blood to the lungs via the pulmonary artery. It plays a crucial role in the pulmonary circulation, ensuring that blood is oxygenated before being delivered to the rest of the body.

Right Ventricle

The lungs are vital respiratory organs responsible for the exchange of oxygen and carbon dioxide between the bloodstream and the environment, playing a crucial role in maintaining the body's metabolic processes. They consist of a complex system of airways and alveoli, which maximize surface area for efficient gas exchange and are protected by the rib cage and diaphragm for mechanical support and ventilation.

Increased right ventricular pressure

Right ventricular hypertrophy (RVH) is the thickening of the muscular walls of the right ventricle of the heart, often due to increased pressure or volume overload. It is commonly associated with conditions such as pulmonary hypertension, congenital heart defects, and chronic lung diseases, and can lead to complications like heart failure if untreated.
