Recurrent Valve Migration During TAVR: Using One Valve to Anchor Another Valve

Area of Science:

• Cardiology
• Interventional Cardiology
• Cardiac Surgery

Background:

• Transcatheter aortic valve replacement (TAVR) is a common procedure for aortic stenosis.
• Hypertrophic and hyperdynamic left ventricles can complicate TAVR by affecting valve deployment and stability.
• Recurrent valve migration is a rare but serious complication during TAVR.

Purpose of the Study:

• To describe a management strategy for recurrent valve migration during TAVR in a patient with a hypertrophic and hyperdynamic left ventricle.
• To present a novel technique for achieving stable valve implantation when standard anchoring is not feasible.

Main Methods:

• A case report detailing a TAVR procedure in a patient with significant left ventricular hypertrophy.
• Intentionally deploying the first TAVR valve deep in the left ventricular outflow tract (LVOT) to serve as an anchor.
• Deploying a second TAVR valve over the first to achieve optimal positioning and hemodynamic function.

Main Results:

• Successful management of recurrent valve migration was achieved.
• The novel two-valve technique provided a stable anchor and optimal hemodynamic result.
• The patient experienced a favorable clinical outcome post-procedure.

Conclusions:

• Deep deployment of a TAVR valve in the LVOT can serve as a viable anchoring site for a second valve.
• This technique offers a potential solution for complex TAVR cases with challenging ventricular anatomy.
• Successful management of valve migration can be achieved with innovative procedural modifications.
