Figure 4. OCT-guided rescue following undersized stent deployment from the LAD into the LM and loss of the original wire position.

Figure 4

A) Abluminal left main stem (LMS) wire position (black line) with the luminal position in the LAD stent segment (white dotted lines). Cross-sectional OCT imaging of the LMS (a) and LAD (b) demonstrate abluminal and luminal wire positions (white asterisks), respectively. B) Use of a dual lumen catheter, loaded on the abluminal wire (white line), facilitating passage of a second wire (blue line) through the true lumen of the stent, confirmed using 3D bifurcation OCT software (C). LAD: left anterior descending coronary artery; LM: left main; OCT: optical coherence tomography
