My 2 premature born daughters are 6 days old. When done the eco on 2nd day PDA & Muscular VSD presence shown in Eco. 1 baby is 1.5 Kgs and has PDA of 2.2mm which has just reduced 2mm with ibrufen medicine for first 5days. In 2nd baby it is 4mm PDA even after 5 days ibrufen medicine there is no reduction in size. Forunately both the babies are active taking almost 15ml milk feed. My concern is do we require any surgery to close this PDA. Also both the babies has diagnoised with muscular VSD, for which dr. mentioned it will close by itself.
