Controlled antegrade and retrograde subintimal tracking (CART) for recanalisation of chronic total occlusions
Authors' conclusion
CART is a useful technique in selected, very complex CTOs tackled with the retrograde approach. Success rates were high, while complication rates were low, considering the high anatomical complexity and baseline patient risk.
