Key result
TMVIV with kissing balloon inflation successfully treats bioprosthesis degeneration without residual gradient or LVOT obstruction.
Why the study?
Transcatheter mitral valve-in-valve implantation into failing surgical bioprosthetic valves has evolved as a promising therapy to avoid redo cardiac surgery in high-risk patients.
Case Report (n=1)
No
Simultaneous kissing balloon inflation between mitral and aortic valves can be a successful technique during transcatheter mitral valve-in-valve implantation to prevent interference with a pre-existing transcatheter aortic valve.
No takes yet. Share an insight, caveat, or question.
May offer a feasible option in high-risk patients with dual bioprosthetic valves; hypothesis-generating for technique validation in larger cohorts.
Mascelloni et al. (2026) conducted a case report in Structural valve degeneration of surgical bioprosthetic mitral valve (n=1). Transcatheter mitral valve-in-valve implantation with simultaneous kissing balloon inflation was evaluated on Post-procedural echocardiographic outcomes (gradient, LVOT obstruction, leak). Transcatheter mitral valve-in-valve implantation with simultaneous kissing balloon inflation successfully treated bioprosthesis degeneration with no residual gradient, LVOT obstruction, or leak.
