Complete atrioventricular canal defect accompanied by
complete atrioventricular block is one of the rare congenital
heart abnormalities. A 32-year-old mother was referred to
our clinic as her fetal ultrasonography was suggestive of
a congenital heart abnormality. Echocardiographic examination
of the newborn showed dextrocardia, a large atrial
septal defect, single atrioventricular valve, ventricular septal
defect, and aortic insufficiency. The newborn was diagnosed
as having complete atrioventricular canal defect, complete
atrioventricular block, and situs inversus totalis, and implantation
of an epicardial pacemaker was decided as the initial
intervention. A VVI pacemaker generator was implanted in
the subdiaphragmatic position and a pediatric epicardial lead
was implanted in a region close to the right ventricular apex.
The patient was extubated on the fifth postoperative day
and was then discharged with improved general condition.
A literature review showed no reported case of complete
atrioventricular canal defect and complete atrioventricular
block accompanied by situs inversus totalis.
