Treatments
Experimental: MyocardialBridge Bypass Graft
The patients with deep(depth\>2mm) and long-segement(length\>25mm) of myocardialbridge receiving myocardialbridge bypass graft surgery(MBBG)，fulfilling the following criteria: 1.presenting with pectoris angina that cannot be effectively relieved by maximum guideline-directed drug therapy; 2. No atherosclerotic plaque or merely mild atherosclerotic stenosis is detected at the proximal or entry of the myocardialbridge confirmed by coronory artery angiography.
Active_comparator: Myocardialbridge CABG
The patients with deep(depth\>2mm) and long-segement(length\>25mm) of myocardialbridge will be allocated to receive myocardialbridge bypass graft surgery(MBBG)，when fulfilling the following criteria: 1.presenting with pectoris angina that cannot be effectively relieved by maximum guideline-directed drug therapy; 2. The moderate-to-severe atherosclertotic stenosis is detected at the proximal or entry of the myocardialbridge confirmed by coronory artery angiography.
Active_comparator: Myocardioalbridge Unroof
The patients with superficial type(depth\<2mm) and short-segement(length\<25mm) of myocardial bridge will be allocated to receive unroof surgery，when fulfilling the following criteria: 1.presenting with pectoris angina that cannot be effectively relieved by maximum guideline-directed drug therapy; 2. No atherosclerotic plaque or merely mild atherosclerotic stenosis is detected at the proximal or entry end of the myocardialbridge confirmed by coronory artery angiography.
