It is most often associated with major chromosomal abnormalities. It is the most common congenital disease in Down syndrome. Our case was an infant with a Down syndrome who was admitted for a dyspnea (stage 3 in New York Heart Association classification) and tachycardia. The diagnosis was made by a transthoracic echocardiography. It showed a rare variety of atrioventricular septal defect without an atrial septal defect. The child was treated successfully with one patch technic and no recurrence was noted. %K AVSD %K VSD %K Dyspnea %K Transthoracic Echocardiography %K Patch %U http://www.scirp.org/journal/PaperInformation.aspx?PaperID=102106
