RESUMEN
Pregnant women with stenotic degeneration of bioprosthetic cardiac valves may require another valve replacement procedure when their symptoms deteriorate with progression of pregnancy, but fetal mortality is higher with cardiac surgery done on cardiopulmonary bypass. Transcatheter valve-in-valve implantation may help to improve the fetal and maternal outcomes in these situations. Double valve-in-valve implantation is rare and has not been reported in a pregnant patient. We report, for the first time, the case of a pregnant woman with stenotic bioprosthetic valves in the mitral and aortic positions, who underwent a successful concomitant, transcatheter, double valve-in-valve implantation through the left ventricular apical route during the second trimester of her precious pregnancy.
