Computed tomography (CT) analysis enhances endoscopic mitral valve surgery planning. Digital simulation using CT reconstructions helps surgeons anticipate challenges and optimize procedures for better outcomes.
Area of Science:
- Cardiovascular Surgery
- Medical Imaging
- Surgical Planning
Background:
- Minimally invasive endoscopic mitral valve surgery necessitates innovative sizing techniques due to small incisions.
- Traditional valve sizers are incompatible with current endoscopic approaches, posing a challenge for accurate procedure planning.
Purpose of the Study:
- To introduce and validate the use of computed tomography (CT) analysis for pre-operative planning in endoscopic mitral valve surgery.
- To demonstrate how CT-based digital simulation can improve procedural strategy and anticipate potential complications.
Main Methods:
- Utilizing dedicated computed tomography (CT) software for detailed analysis of mitral valve anatomy.
- Creating digital reconstructions and simulating valve implantation using digital prostheses phantoms.
- Assessing the feasibility of planning cannulation, valve implantation, and identifying risks like circumflex artery injury or left ventricular outflow tract obstruction.
Main Results:
- CT analysis allows for precise pre-operative planning, overcoming the limitations of direct sizing in endoscopic procedures.
- Digital simulation enables surgeons to anticipate and mitigate risks, including vascular injury and outflow tract obstruction.
- The proposed method facilitates the selection of optimal cannulation and valve implantation strategies.
Conclusions:
- Computed tomography (CT) analysis and digital simulation represent a significant advancement in pre-operative planning for endoscopic mitral valve surgery.
- This approach enhances surgical strategy, improves safety, and optimizes outcomes in minimally invasive mitral valve interventions.
