Angioplasty at Coronary Bifurcation <Kissing (Two-Guide, Two-Balloon) and Single-Guide, Two-Wire Technique>

Balloon angioplasty of stenosis involving a bifurcation of coronary arteries carries a significant risk of iatrogenic permanent occlusion of one of the adjacent branches. In order to prevent this complication, kissing balloon technique, inhitially, used for aortoplasty in Leriche synrome, was introduced into coronary angioplasty. Alternatively Oesterle described the single-guide, two-wire technique which is less traumatic with nearly equal outcomes. Among 200 coronary angioplasty cases done in our laboratory, 3 cases of unstable angina pectoris with stenosis involving major bifurcation sites were encountered. In 2 cases with stenosis involving left anterior descending artery and diagonal branch, kissing balloon technique was performed. Single-guide, two-wire technique was performed in remaining 1 case with stenosis of posterior descending and posterior lateral branchs. The outcome were successful without major complications.
