Truncus arteriosus


There is only one great artery (truncus arteriosus) originating from the base of the heart providing both pulmonary and systemic circulation. The truncal valve is obviously larger than a normal semilunar valve, with a variable number of leaflets from only one up to five and even six leaflets (extremely rare); most frequently the truncal valve has three (42-61% of cases) or four leaflets (24-31% of cases); a truncal valve with two leaflets is rare (5% of cases). The valve is generally located above the ventricular septal defect, almost always present, and the leaflets can be dysplastic and/or thickened with resulting stenosis, regurgitation (in at least 20% of cases), or both. The ventricular septal defect results from the absence of the infundibular septum, and is generally high, anterior and unrestrictive. Absence of the ventricular septal defect is anecdotal.
