A 6-day-old boy born with a rare congenital condition underwent complex open-heart surgery. The baby, named Rumi, has hypoplastic left heart syndrome, which means part of his heart is underdeveloped. His parents, a California couple, are involved in a legal battle over his parenthood. The baby's birth resulted from a surrogacy arrangement with a woman from Alaska. Rumi's condition requires multiple surgeries early in life, and his parents waited anxiously as he underwent the first of these procedures.

Further details about the legal battle and the surrogacy arrangement are available from the source. The baby's condition and the surgery he underwent are part of a complex and high-risk medical situation.
