Case Presentation
A 7 days old female patient presented at a local clinic for newborn metabolic screening. The patient displayed symptoms of dehydration and jaundice, along with an unspecified heart murmur. The mother reported substance abuse (alcohol, cannabis, and cocaine) during pregnancy. After birth, the patient was hospitalized for seven days due to hyperbilirubinemia, microcephaly, and an unspecified congenital heart defect.
After consulting a pediatric cardiologist, a right ventricular-coronary fistula diagnosis was suspected. Treatment with furosemide and spironolactone was initiated, and the patient was referred to a third level hospital for further assessment and management. During the examination, the patient appeared stable and asymptomatic. Upon auscultation, a regurgitant murmur at the mesocardium was identified, with no other significant findings.
