What is Pulmonary Stenosis?

1. After tiring, palpitations, shortness of breath, chest pain, or syncope, severe cyanosis and right heart failure. Patients with mild stenosis may be asymptomatic.

Pulmonary stenosis

Pulmonary stenosis refers to the narrowing of the passage between the right ventricle and the pulmonary artery due to congenital malformations, and the ventricular septum is intact. This is one of the common congenital cardiovascular diseases. The common types of stenosis are valve stenosis, funnel stenosis, and pulmonary artery stenosis. They may exist individually or in combination. The symptoms and development of the disease are related to the degree of stenosis. Those with mild stenosis may be asymptomatic, those with severe stenosis may appear early, and gradually develop cyanosis and heart failure. The surgical effect of this disease is definite, and the cure rate is high. Most of the patients with poor curative effect or death were those who did not receive treatment in time, were in critical condition or accompanied by other heart deformities. Therefore, early diagnosis and early treatment should be made.

1. After tiring, palpitations, shortness of breath, chest pain, or syncope, severe cyanosis and right heart failure. Patients with mild stenosis may be asymptomatic.

2. The second intercostal space on the left margin of the sternum and the rough systolic jet-like noise, the second sound of the pulmonary valve with tremor weakened or disappeared.

Diagnose based on

1. Palpitations, shortness of breath, chest pain, or syncope after exertion.

2. The second intercostal space on the left margin of the sternum and the jet-like noise in the rough systolic phase, the second sound of the arterial valve with tremor weakened or disappeared.

3. ECG: the electrical axis is skewed to the right, the P wave is sharp, and the right ventricle is hypertrophic.

4. On X-ray examination, the right ventricle was enlarged, the pulmonary artery cone was bulged, and the hilar blood vessels were reduced in shadow and slender.

5. Color Doppler echocardiography: the right ventricle is enlarged to determine the anatomical location and extent of stenosis.

6. Cardiac catheter examination: The systolic pressure step between the right ventricle and the pulmonary artery exceeds 1.3KpA.

Pulmonary artery stenosis treatment principles

1. The patient has no obvious clinical symptoms, the ECG is normal, and the X-ray examination of the heart shadow is normal, without surgery.

2. Symptoms are obvious, electrocardiogram or X-ray shows right ventricular hypertrophy, right ventricular pulmonary arteriopulmonary systolic pressure difference is above 8KPA, all should be treated surgically.

3. Surgical treatment: Pulmonary stenosis under external reflux.

Principles of Pulmonary Artery Stenosis

1. Cases with good cardiac function before surgery are mainly anti-heart failure drugs, vasodilators, antibiotics and other auxiliary drugs.

2. Patients with severe stenosis and preoperative cardiac dysfunction. Anti-heart failure, vasodilators, diuretics, anti-shock drugs, antibiotics and other comprehensive treatments should be used before and after surgery to prevent complications and the course of treatment depends on the condition.
