The absence of pulmonary artery closure on palpation is the clinical manifestation of Ebstein syndrome. Ebstein syndrome, also known as Ebstein malformation, is a condition in which the tricuspid septal and/or posterior valves occasionally attach to the right ventricular wall near the apex along with the anterior valve, accounting for approximately 0.5% to 1.0% of precardiac disease. Both systolic and diastolic pressures are elevated in the atrial chambers. There may be a systolic pressure difference on both sides of the pulmonary valve and a diastolic pressure difference on both sides of the tricuspid valve. The former may be due to an overgrown tricuspid valve leaflet that partially obstructs the right ventricular outflow tract; the latter is due to tricuspid valve malformation and tricuspid orifice stenosis. Ebstein syndrome is a congenital heart disease with a very poor prognosis. These patients can die shortly after birth or remain asymptomatic into adulthood. In general, the earlier the onset of cyanosis and congestive heart failure, the worse the prognosis; the larger the heart, especially in the short term with progressive enlargement, the worse the prognosis; the more severe the tricuspid valve malformation on cardiovascular imaging, the worse the prognosis (worse in cases showing stenosis than incomplete closure); and the worse the prognosis in cases with severe complications. The main cause of death in this disease is congestive heart failure, and a few patients may die suddenly due to arrhythmias. In addition, death can be caused by complications such as embolism and infection. Therefore, it is important to actively prevent and treat the absence of pulmonary artery closure on palpation. The daily prevention methods of palpable absence of pulmonary artery closure sense: 1, strengthen physical exercise, enhance the body’s ability to resist disease, pay attention to rest, do not participate in heavy physical labor. 2.Actively and effectively treat streptococcal infection, such as eradicating tonsillitis, dental caries and paranasal sinusitis and other chronic lesions. 3.Give high-calorie easy-to-digest diet, such as fish, meat, eggs, milk, etc., small amount and many meals, give more vegetables and fruits. 4.Give low-salt diet to those with cardiac insufficiency, and limit water intake. 5.Prevent respiratory tract infection. The room should have sufficient sunlight, fresh air and suitable temperature to prevent rheumatic activities caused by respiratory infections and aggravation of the disease.
