The primary cause of pulmonary hypertension related to pulmonic stenosis is indeed a congenital anomaly. Pulmonic stenosis is often a result of a structural heart defect present at birth, affecting the valve that controls blood flow from the right ventricle to the pulmonary artery. This narrowing or obstruction leads to increased pressure in the right ventricle, ultimately causing elevated pressures in the pulmonary circulation, which manifests as pulmonary hypertension.

Congenital anomalies are among the most significant contributors to pulmonic stenosis, as they can disrupt normal blood flow dynamics, causing the heart and lungs to work harder. Over time, this increased workload can stress the heart and lead to long-term complications, including pulmonary hypertension.

Other conditions listed, such as cardiomyopathy, infective endocarditis, and coronary artery disease, pertain more to acquired heart diseases and may lead to different forms of cardiovascular complications but are not directly linked as primary causes of pulmonary hypertension specifically due to pulmonic stenosis.
