Emergency treatment of thrombus in right coronary artery and aortic root in a newborn with acute myocardial infarction

Abstract

Perinatal myocardial infarction caused by aortic root and coronary artery thrombosis in neonatal period is extremely rare and has a gloomy prognosis that may cause devastating complications. A 3-h newborn baby who had acute myocardial infarction findings on postnatal electrocardiography had a thrombus in the aortic root with hyperechogenic right coronary artery region, and impaired right ventricular functions on echocardiography. The patient was urgently operated and thrombus was successfully removed from the aortic root and the right coronary artery. In conclusion, for large thrombi posing a risk for embolization in the aortic root, an urgent surgical thrombectomy procedure should be performed.
