This study demonstrates a novel, feasible approach for percutaneous mitral valved stent implantation in porcine hearts. The technique ensures excellent stent fixation, paving the way for minimally invasive mitral valve interventions.
Area of Science:
- Cardiovascular Surgery
- Medical Devices
- Minimally Invasive Procedures
Background:
- Transcatheter mitral valved stent implantation is a promising but challenging procedure.
- Existing techniques face difficulties in achieving secure stent fixation.
Purpose of the Study:
- To present and evaluate a novel approach for percutaneous mitral valved stent implantation.
- To assess the feasibility, implantation time, and fixation of the novel technique.
Main Methods:
- A percutaneous transapical access was combined with various transatrial/transseptal approaches.
- Apical fixation and occlusion were achieved using an Amplatzer occluder.
- The technique was tested in 22 porcine hearts in vitro under fluoroscopy and endoscopy.
Main Results:
- Percutaneous mitral valved stent implantation was successful in all cases.
- Excellent apical fixation was achieved in all 22 porcine hearts.
- Implantation times were comparable between fluoroscopic and endoscopic guidance.
Conclusions:
- The feasibility of this novel percutaneous mitral valved stent implantation technique has been demonstrated in vitro.
- Further studies are needed to evaluate the efficacy of this minimally invasive approach.
