The "great arteries" in this anomaly refer to the aorta and the pulmonary artery, the two major arteries carrying blood away from theheart. In cases of transposition of the great arteries, these vessels arise from the wrong ventricle. They are "transposed" from their normal position so that the aorta arises from the right ventricle and the pulmonary artery from the left ventricle.
Subtle variations in heart anatomy—such as the arrangement of the arteries that feed the heart—can negatively impact surgical outcomes if not identified ahead of time. We utilize the most advanced techniques available for precisely determining the patient’s cardiac anatomy, with interpretation by highly experienced cardiologists. CHDs affect nearly 143,782?births per year in the Finland. Further research is being conducted to determine the best surveillance interval to monitor the disease.
