ABSTRACT
Objective To explore the effectiveness and safety of branch protection technique with provisional stenting strategy in coronary bifurcation lesions by utilizing jailed balloon protection technique after pre-dilation in branch with cutting balloon. Methods 32 patients undergone jailed balloon protection technique after pre-dilation in branch with cutting balloon during January, 2015 to May, 2016 in Peking University of People's Hospital were enrolled consecutively in our study. 32 patients were involved including a total of 32 bifurcation lesions which were medina type 1,1,1 (n = 25, 78. 1% ), Medine type 0,1,1 (n =5,15. 6% ) and Medine type 1,0,1 (n = 2, 6. 3% ). For side branch diameter ≥2. 5 mm, the diameter ratio of cutting balloon to side branch was 1: 1. The angiography success rate after using branch protection during main branch stent implantation, perioperative complications and major adverse cardiac events were observed. Results ( 1 ) The angiography success rate of branch protection was 100% . ( 2 ) No perioperative complications and major adverse cardiac events were observed. Conclusions Side branches were effectively protected in provisional stenting strategy by applying jailed balloon protection technique after pre-dilation using branch cutting balloon.
ABSTRACT
Objective To evaluate the feasibility of jailed-balloon technique(JBT) in the treatment of true coronary bifurcation lesions.Methods From March 2013 to October 2014,a total of 71 patients who received coronary angiography,were diagnosed as true coronary bifurcation lesions and then underwentpercutaneous coronary intervention(PCI) in the Department of Cardiology of the Second Affiliated Hospital of Kunming Medical University was divided into group A(jailed balloon side branch protection group,28 cases) and group B(traditional side branch protection group,43 cases).The perioperative complications,X-ray exposure time,the number of intervention supplies,the total expenses,the incidence of adverse cardiovascular events and other indicators between the groups were compared,and the feasibility of JBT was evaluated.Results There were no significant differences between the two groups in perioperative complications(P＞0.05),postoperative adverse cardiovascular events and restenosis rate of side branch after angiography(P＞ 0.05),but the PCI related indicators (including the balloon use number,PCI operation time,the amount of X-ray exposure,wire number,the amount of contrast agent and operation cost) in group A were significantly lower than those in group B(P＜0.05).Conclusion JBT applied in the treatment of true coronary bifurcation lesions can reduce the operative time,X-ray irradiation time and related medical expenses.
ABSTRACT
Objective To evaluate the safety and efficacy of treating bifurcation lessions with jailed-balloon technique in simple strategy. Methods Ninety patients with bifurcation lessions (Duke D or F type) who received the side branch protection technique with simple strategy were involved in a single center retrospective analysis. Patients were randomly divided into jailed-balloon protection group (n=48) and jailed guidewire group (n=42). The process operating, procedural success of percutaneous coronary intervention (PCI) and percutaneous transluminal coronary angioplasty (PTCA), complications and the results of follow-up were investigated. Results The clinical baseline date and the bifurcation lesions were not significant different between jailed-balloon group and jailed guidewire group (P>0.05). The procedural success rate of PCI was 100%in jailed-balloon group and 97.6%in jailed guidewire group, no significance difference user between two groups (P>0.05). The perioperative complications (the rate of no reflow) was lower in jailed-balloon group than those of jailed guidewire group (1.0%vs. 19.0%, P0.05) and the maximum restenotic level (19.24%vs. 21.46%,P>0.05) in the main branch were not significant different between jailed-balloon group and jailed guidewire group. But the maximum restenotic level in the opening of side branch was lower in jailed-balloon group than that of jailed guidewire group (51.2% vs. 72.46%, P < 0.01). Conclusion The jailed-balloon technique reduces the operation complications, exposure time and amount of contrast agent, and also saves surgical consumables. The procedure of branch with simple strategy is safe and effective in treatment of bifurcation lesions.
