The scheme of the percutaneous coronary intervention. (a) The first guide wire passed through the false lumen from the midportion of the LMT to the proximal site of the LAD. (b) The second guide wire was inserted into the true lumen of the LCX. (c) The third guide wire was initially introduced into the true lumen of the obtuse marginal branch using a double-lumen catheter that was placed in the true lumen of the LCX. (d) We pulled the third guide wire back and controlled it toward the true lumen of the LAD, which was located under the first guide wire from the right anterior oblique and caudal view. (e) After the successful rewiring, the first guide wire was removed. (f) A drug-eluting stent was deployed from the LMT to LAD. LMT: left main trunk; LAD: left anterior descending artery; LCX: left circumflex artery; OM: obtuse marginal branch.
