MSRA-1981

You are requested to assess a premature infant born at 34 weeks, 48 hours after delivery without any complications. During the examination, you observe a continuous ‘machinery-like’ murmur and a left subclavicular thrill. Additionally, you notice a bounding pulse and a widened pulse pressure. There are no indications of cyanosis or crackles on auscultation. The mother confirms that there were no complications during pregnancy, and antenatal scans and screening did not reveal any abnormalities. There is no family history of significant illnesses. What would be the most appropriate management option for this probable diagnosis?
