BACKGROUND: First described by Holt and Oram in 1960 in a four-generation family with atrial septal defects and thumb abnormalities, is an inherited disorder characterized by abnormalities of the upper limbs and heart. This syndrome is characterized by upper extremity malformations involving radial, thenar, or carpal bones. An abnormal carpal bone is present in all affected individuals and may be the only evidence of disease. About 75% of individuals with Holt–Oram syndrome (HOS) have a congenital heart malformation which may include an atrial or ventricular septal defect or heart block. In rare cases, the syndrome can affect other organs and systems which can be life threatening.
CASE REPORT: Here, we present a newborn with clinical and radiologic features of HOS consisting of bilateral asymmetric hypoplastic thumbs, generalized brachydactyly, limited bilateral supination due to radioulnar synostosis, and associated with complex heart disease and hypoplastic tricuspid valve.
CONCLUSION: In our case HOS is associated with complex congenital heart defects including atrial septal defect, ventricular septal defect with hypoplastic tricuspid valve. Based on the listed literature we didn’t find any other case where tricuspid valve was affected.
