Effectiveness and safety of branch protection technique:jailed balloon protection technique after pre-dilation in branch with cutting balloon / 中国介入心脏病学杂志

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.
