Myocardial Bridge Bypass Graft: A Novel Surgical Procedure for Extensive Myocardial Bridges.

In patients with myocardial bridges (MBs) and insufficient medical management, the optimal surgical strategy remains undetermined. Based on computer simulations we developed a novel procedure, MB bypass grafting, that showed better hemodynamics compared with coronary artery bypass grafting in a simulation study. In this novel procedure the left internal mammary artery was used to connect the proximal and distal ends of the MB. For the first time we used MB bypass grafting to treat a patient with extensive MB. The patient recovered well after surgery, and the left internal mammary artery graft remained patent 3 months postoperatively.
