Interventions

PROCEDUREMBBG

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.

PROCEDUREMB CABG

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. The moderate-to-severe atherosclerotic stenosis is detected at the proximal or entry of the myocardialbridge confirmed by coronory artery angiography.

PROCEDUREMB unroof

The patients with superficial type(depth\<2mm) and short-segement(length\<25mm) of myocardial bridge will be allocated to receive myocardialbridge "unroof" surgery，when fulfilling the following criteria: 1.presenting with pectoris angina that cannot be effectively relieved by maximum guideline-directed drug therapy; 2. The MB was superficial and short confirmed by coronory artery CT angiography.
