Congenital Heart Surgery Nomenclature and Database Project: double outlet left ventricle.
Double outlet left ventricle (DOLV) is a type of ventriculoarterial connection in which both great arteries arise entirely or predominantly from the left ventricle. Although it was initially believed that bilateral absence of conus is a prerequisite for such diagnosis, all possible conal configurations have been described in this malformation. The morphology of DOLV is encompassed by a careful description of the ventricular septal defect (VSD) with its relationship to the semilunar valves, the presence or absence of pulmonary outflow tract obstruction (POTO) and aortic outflow tract obstruction (AOTO), and the presence or absence of associated cardiac lesions. The preferred surgical treatment involves the connection of the right ventricle to the pulmonary circulation by an intraventricular tunnel repair connecting the VSD to the pulmonary semilunar valve. This ideal surgical therapy is not always possible, because of the presence of confounding anatomical barriers. Several alternative surgical procedures have been devised to accommodate these more complex situations. A framework for the development of the DOLV module of a pediatric cardiac surgical database is proposed.
