Biliary atresia in a 3-month-old infant (case report).

Biliary atresia (BA) is a congenital disease that occurs when extrahepatic bile ducts are either absent or deficient, resulting in liver fibrosis, portal hypertension, and eventually cirrhosis. It is the most common cause of persistent obstructive jaundice in newborns lasting more than two weeks is this condition. Abdominal ultrasound (US) is the primary imaging technique used to diagnose BA, while computed tomography (CT) is reserved for more complex cases.

Clinical predictors of marked improvement in left ventricular performance after cardiac resynchronization therapy in patients with chronic heart failure.

Background: Previous studies have shown that cardiac resynchronization therapy (CRT) improves cardiac performance and decreases mortality and hospital admission rates. However, it is not yet clear which patients will benefit from the procedure the most. The purpose of the study was to identify the pre-implant characteristics that better predict which patients will have the best outcome after CRT.
