Transcatheter double valve-in-valve implantation via LV apex succeeds in a pregnant woman with stenotic bioprostheses.
Case Report (n=1)
This is the first reported case demonstrating the feasibility of transcatheter double valve-in-valve implantation via a left ventricular apical approach in a pregnant patient, offering an alternative to high-risk surgery on cardiopulmonary bypass.
Double valve-in-valve in pregnancy supports procedural feasibility; hypothesis-generating and should not yet change practice.
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.

Chengode et al. (2018) conducted a case report in Stenotic degeneration of bioprosthetic cardiac valves during pregnancy (n=1). Transcatheter double valve-in-valve implantation through the left ventricular apical route was evaluated on Procedural success. Concomitant transcatheter double valve-in-valve implantation through the left ventricular apical route was successfully performed in a pregnant woman with stenotic bioprosthetic valves.
