Case Report
A male newborn with a gestational age of 38w and birth weight of 2900g was consulted to our clinic because of murmur and 5% difference in pulse oximetry screening test in first day of life. Physical examination was normal except 2/6 cardiac murmur. Echocardiography revealed a small sized apical muscular ventricular septal defect and ductal patency with a large ductal aneurysm, narrowed pulmonary end with left to right shunt and swirling motion in the aneurysm (Fig.1a and 1b, Video 1 and 2). The patient was asymptomatic, therefore we decided for clinical follow up without medication. On the third day of life, echocardiography revealed closed pulmonary end of the ductus and presence of trombus in the aneurysm extending towards decscending aorta (Fig. 1c and Video 3). Surgical resection of ductal aneurysm was enrolled because of risk of embolism (Fig. 1d). Post-operative echocardiography showed residual thrombosis in the aortic side, which fully disappeared on the second week of life with low molecular weight heparin treatment.
