Precision in CTO Recanalization And Side-Branch Protection With The ETcath200

Following contralateral angiography confirming that the guidewire had successfully entered the true lumen of the LAD, 2.0 × 20 mm and 2.5 × 20 mm balloons were used sequentially for lesion pre-dilatation. Antegrade angiography confirmed restoration of antegrade blood flow in the LAD.
The robotic system was then re-engaged, and the operator skillfully and precisely advanced the working guidewire into the first diagonal branch, followed by pre-dilatation of the ostial lesion using a 2.0 × 20 mm balloon.
