A Incorrect. In addition to closing the atrial and septal defect, the goal of surgery for atrioventricular septal defect is not to close a patent ductus arteriosus, which accompanies the atrioventricular septal defect.
B Incorrect. In addition to closing the atrial and septal defect, the goal of surgery for atrioventricular septal defect is not to insert a coil or similar device to close off the defect.
C Correct. In addition to closing the atrial and septal defect, the goal of surgery for atrioventricular septal defect is to construct new mitral and tricuspid valves from the common A-V valve. AVC is associated with a septal defect in the atrium and ventricle, and involvement of the A-V valves. When the heart is developing the atrial and ventricular septa are not fully completed, thus, causing the mitral and tricuspid valves to develop inappropriately.
D Incorrect. In addition to closing the atrial and septal defect, the goal of surgery for atrioventricular septal defect is not to close the communication between the pulmonary artery and the aorta.
