Severe LVOT Obstruction After Transcatheter Mitral Valve Replacement

Key Points

Severe obstruction after transcatheter mitral valve replacement may lead to hemodynamic compromise, requiring prompt action.
The intervention involved the implantation of a vascular stent to resolve the obstruction effectively.
This analysis presents a complex case highlighting the risks associated with TMVR procedures and their complications.
Timely interventions are crucial for mitigating risks, suggesting improvements in treatment protocols for TMVR.

Abstract

LVOTO after TMVR is a feared and potentially fatal complication that may still occur despite thorough preprocedural planning. This complex case demonstrates that LVOTO with hemodynamic compromise after TMVR necessitates timely intervention. With today's advanced interventional techniques, this salvage procedure with vascular stent implantation in the LVOT represents a feasible treatment option.
