title: Left hemitruncus with normal right-sided pressures in an adult.
abstract: Hemitruncus is a rare congenital heart disease. Anomalous origin of the left pulmonary artery is not only rare but also pathogenetically different from anomalous origin of the right pulmonary artery from the ascending aorta. In most cases in isolated hemitrucus pressures in the right ventricle and the normally originating pulmonary artery are systemic or suprasystemic. We present a rare case of anomalous origin of the left pulmonary artery from the ascending aorta diagnosed in an adult with normal pressures in the right ventricle and normally originating pulmonary artery. To the best of our knowledge, this unique haemodynamics has never been reported in the literature.
