Conditions
Brief summary
To protect side branch more effectively, a new technique called jailed balloon technique were compared with conventional wire protection technique in this study. The hypothetic outcomes of this study are the jailed balloon technique can reduce the rate of side branch occlusion and make it easier to rewire the side branch jailed by stent.
Interventions
Coronary artery disease patients with side branch arising from target lesions are randomly divided into 2 groups. Group 1 patients will use new technique: leaving 1 small balloon in side branch ostium before main branch stent inflation, proximal part of balloon protruded into the main branch and jailed between the main branch stent and the vessel wall. After inflation of main branch stent at low pressure, if the blood flow of side branch were affected, then the balloon were inflated immediately

Group 1 patients will use new technique: leaving 1 small balloon in side branch ostium before main branch stent inflation, proximal part of balloon protruded into the main branch and jailed between the main branch stent and the vessel wall. After inflation of main branch stent at low pressure, if the blood flow of side branch were affected, then the balloon were inflated immediately to recover the side branch blood flow. Rewire the side branch wire through the stent cell and post dilate stent with post-dilation balloon at high pressure to make sure the stent expanded fully. Side branch can be post dilated or stented according to the operator's intention. For one side branch, this technique will occur only once and will spend about 1 hour to finish the whole procedure.
