Clinical manifestations include heart murmur, shortness of breath and increased load intolerance, left ventricular hypertrophy and dilatation of the left atrium. Partial forms, involving only two or three out of the four specific anomalies, are also described and occasionally other cardiovascular anomalies (e.g. bicuspid aortic valve, patent ductus arteriosus, ventricular septal defect) may be associated.OrphaNetINSERM, 2021
