Werner's syndrome is an extremely rare genetic disorder of the autosomal recessive type, characterized by features suggesting premature aging in young adulthood. Because of the concomitant hypogonadism, pregnancy among patients with Werner's syndrome occurs extremely rarely. We present a case of a successful outcome of pregnancy complicated by Werner's syndrome in a 34-year-old primigravida. The reason for early delivery by caesarean section, at 34th week of pregnancy, was exacerbation of coronary symptoms, with early signs of cardiac insufficiency. A healthy female child was born in a good condition, with birth weight of 1950 g.
