[Pregnancy in patients operated on for congenital or acquired heart diseases].

The Author considers some cases of pregnancies following to cardiovascular operations; these cases were observed at the Clinica Ostetrica e Ginecologica of the University of Rome since 1953 until today. It is in evidence that: 1) operations for mitral valve commissurotomy almost always contributed to carry out those pregnancies successfully; 2) operations for radical corrections of congenital malformations - including three cases of tetralogy of Fallot - favoured an almost normal evolution of pregnancy.
