Talk to Pediatrician on Left Ventricular Systolic Dysfunction

Assalamo alaikum. Kindly tag a paediatric cardiologist. My 21 month old son got diagnosed with left ventricular systolic dysfunction about a month ago. He was admitted for 10 days in which he was given dobutamine, steroids, diuretics, ivig, loprin, captopril. Upon discharging from the hospital the doctors switched him to oral medicine instead of injectables and in his echo reports his condition showed mild LV dysfunction. I'll be taking him to the doctor once one month is completed but I have a question that I want to ask here.

Will my son recover completely or he'll have to be on medicine his whole life? I saw on Google that people with LVD will likely lose their life after max 5 years, if my son's condition gets better will he still come under this risk? Kindly explain these to me.
