Effect of oral propranolol in pediatric chest pain with tricuspid valve regurgitation

  Chest pain is one of the major complications of tricuspid valve regurgitation. Propranolol is a non-selective beta blocker that is commonly used to treat hypertension, irregular heartbeat, and cardiac pain and migraine headaches. The purpose of the present study was to evaluate the effect of oral propranolol on chest pain in children with tricuspid valve regurgitation. In this clinical trial, 38 children aged 5 to 16 years with a symptom of chest pain due to moderate and severe tricuspid valve regurgitation were randomly divided into two groups. The case group was treated with propranolol 10 mg daily (1_0.5 mg/kg/d). Before and three months after the intervention, echocardiography was performed to assess the severity of tricuspid valve regurgitation, cardiac output, systolic and diastolic pressure and pulmonary blood pressure. In addition, patients were questioned about the duration and frequency of chest pain. There was no significant difference between two groups in the frequency and percentage of sex, location, associated heart disease and pain severity. Before intervention, pulmonary blood pressure, tricuspid valve regurgitation and ejection fraction were not significantly different between intervention and control groups. Tricuspid valve regurgitation had a significant and positive correlation with pulmonary blood pressure (p Propranolol significantly reduces chest pain in children with tricuspid valve regurgitation.
