Simultaneous transcatheter aortic valve implantation and mitral valve-in-valve procedures require careful planning to avoid prosthetic valve interactions. Preprocedure imaging and simulations effectively predicted and managed these potential complications in three patients.
Area of Science:
- Cardiovascular Surgery
- Interventional Cardiology
- Biomedical Engineering
Background:
- Simultaneous transcatheter aortic valve implantation (TAVI) and mitral valve-in-valve (MViV) procedures present a risk of prosthetic valve interactions.
- Effective preprocedural planning is crucial for mitigating these risks.
Observation:
- Computerized tomography (CT) and bench model simulations were utilized for preprocedure planning in three patients undergoing combined TAVI and MViV.
- These methods aimed to predict potential interactions between the implanted prosthetic valves.
Findings:
- The study details the clinical and procedural aspects of these three cases.
- Preprocedure planning using CT and bench models successfully identified and informed the management of prosthetic valve interactions.
Implications:
- This approach enhances the safety and efficacy of complex TAVI and MViV procedures.
- Advanced imaging and simulation techniques are valuable tools for complex structural heart interventions.
