Sayang, ini really serious medical matter, kena consult dengan paediatrician atau cardiologist yang handle baby tu. Mereka boleh explain best about the surgery, recovery, dan long-term outlook based on baby's specific condition. I know it's scary, first-time mum. A few of us in the circle pernah go through medical emergencies dengan anak, and honestly the doctors are the best source untuk detailed, accurate info. If you're worried about baby's current condition, jangan delay, go to the hospital or clinic. Sending you strength, mama. You're doing the right thing by asking questions.
