Fetal exposure to secondary tobacco smoke septal and right-sided defects. Maternal systemic viral infections such as rubella (patent ductus arteriosus, pulmonic stenosis, coarctation of aorta) or cox-sackie b5 (endocardial fibroelastosis) increased maternal age ventriculoseptal defect, tetralogy of fallot. Maternal metabolic disorders such as phenylketonuria (coarc-tation of aorta and patent ductus arteriosus), diabetes mellitus (ventricular septal defects, cardiomegaly, transposition of great arteries), and hypercalcemia (aortic stenosis, pulmonic steno- sis, aortic hyperplasia) High altitude patent ductus arteriosus, atrial septal defect.
