Echo sounds can be heard in the pulmonary valve area

It refers to the narrowing of the outlet of the pulmonary artery, resulting in obstruction of right ventricular bleeding, including stenosis of the pulmonary valve, stenosis of the right ventricular funnel and stenosis of the pulmonary valve, the main trunk and branches of the pulmonary artery. Those with severe stenosis have poor development. The anterior region of the heart bulges, and the heart dullness circle expands significantly. There is a grade 4-5 rough systolic murmur in the intercostal space on the left margin of the sternum. Conducts to the left axilla, under the clavicle and left shoulder. The narrow murmur in the funnel is the loudest, and the part is low. The noise is related to the degree of stenosis, and it is accompanied by fine tremor in systole. Pulmonary valve second sound weakened or disappeared. In patients with mild to moderate stenosis, systolic jetting sounds can be heard in the pulmonary valve area.
