Placement of the LV lead of the CRT device can be difficult and for some cardiologist, selecting the optimal site for the LV lead is a process of trial and error.
When placing the lead, infarcted tissue and its border zone are to be avoided because little effect can be expected from the stimulation of scar (dead) tissue.

In addition, the LV lead is expected to exert its best effect in an area of the heart that has delayed contraction in comparison to neighboring tissue (Figure 1B and green area in Figures 1 A,B,C,D).

CARTBox merges the myocardial scar area (Figure 1A) and the LV lead target area (Figure 1B) with fluoroscopic (X-ray) images of the coronary veins and displays this information real time in a single screen during placement of the lead. As a result, the lead can be placed in a coronary vein in a late contracting area, away from the infarcted tissue (see Figures 1C and 1D).

Our solution is compatible with any commercial fluoroscopy and any MRI equipment.
