Usually diagnosed incidentally, MH may coexist with congenital heart defects, chest wall abnormalities and certain genetic syndromes such as Down syndrome. A 4-year-old boy with Down syndrome underwent simultaneous repair of MH and closure of a ventricular septal defect (VSD). A vertical midline sternotomy was performed, and the VSD was repaired using the right atrium approach. Subsequently, MH repair was conducted. Three weeks after the surgery, this patient developed a complete heart block, which lead to the implantation of a VVI pacemaker.
