Resumen

Among congenital anomalies of the tricuspid valve, Ebstein’s anomaly is the most frequent, followed by tricuspid valve dysplasia[1], and, more rarely, congenital tricuspid valve calcification. All these conditions may present with tricuspid regurgitation, which can become severe and lead to early hemodynamic compromise.We present the case of a one-month-old infant with persistent cyanosis and hemodynamic instability. Prostaglandin infusion was initiated to maintain ductal patency and ensure pulmonary blood flow, achieving hemodynamic stabilization. Echocardiography revealed severe tricuspid regurgitation with a markedly echogenic anterior leaflet, without apical displacement of the valve leaflets. Cardiac tomography further suggested calcification of the tricuspid valve.This case represented a diagnostic and therapeutic challenge. Intraoperative findings confirmed congenital tricuspid valve calcification, which precluded repair. The patient underwent surgical intervention with a favorable postoperative course. Pathological examination corroborated the diagnosis. The patient was discharged and continues follow-up in outpatient pediatric cardiology.This case underscores that surgical management should be guided by tricuspid valve morphology and clinical presentation [2], with some patients requiring early intervention.
