Theme 4: Improved guidance in image guided interventions

Many types of cardiovascular interventions are currently performed under image guidance, for instance stent placement and cardiac ablation therapy. The success of such procedures heavily relies on the precise localization of the catheter position with respect to the treated site, which often is heavily moving and deforming due to breathing and heart contraction. Improved image guidance through computer aided navigation supported by motion correction algorithms would therefore greatly improve the efficacy of cardiovascular interventions. This is a novel and challenging field of research. (Figure 5).

 
Figure 5. Fusion of late enhancement MRI with the Carto bipolar voltage approach provides essential information for the interventional cardiologist about the positions in the myocardial wall or outflow tract where ablations should take place. This diminishes the procedure time and X-ray radiation significantly, while improving the success rate of the procedure. Preferably this should be done on-line and in real-time in the catheterization laboratory, requiring compensation for breathing, etc.
