RESUMEN
Hardikar syndrome (HS) is a MED12-related ultra-rare multiple congenital malformation syndrome known to affect the gastrointestinal, cardiac, and genitourinary systems among other features including cleft lip/palate and pigmentary retinopathy. Only 10 patients affected with HS have been previously described in literature, of which seven were molecularly confirmed. We report a 20-year-old and a 13-month-old patient with HS diagnosed by exome sequencing bringing the total number of clinically diagnosed cases to 12 and MED12 associated to 9. We describe previously unreported molecular and clinical findings associated with HS and review all reported cases to permit prompt diagnosis, appropriate management, and genetic counseling of HS patients.

Portal hypertension because of liver cirrhosis is a significant cause of morbidity and mortality. Treatment options in these patients include liver transplant, symptomatic treatment of oesophageal varices via endoscopic treatment and symptomatic management of ascites. Portosystemic shunt creation can be challenging in newborns and infants. We present a newborn with Trisomy 21, severe portal hypertension secondary to neonatal cirrhosis, oesophageal varices and upper GI bleeding, severe ascites refractory to medical management who underwent ductus venosus stenting as a palliative procedure. He demonstrated remarkable clinical improvement with no subsequent upper GI bleed and resolution of ascites till his last follow-up at 12 months of age. To the best of our knowledge, stenting of the patent ductus venosus to create a portosystemic shunt to relieve portal hypertension has not been reported in English literature.
