title: A technique for type 4a coronary bifurcation lesions: initial results and 6-month clinical evaluation.
abstract: In routine practice, lesions in coronary bifurcations are frequent. This relatively high frequency may be underestimated due to the presence of  false  bifurcation lesions (lesions of the main branch without significant lesion of the sidebranch), which may become true bifurcation lesions after stenting due to axial plaque redistribution. In this report, we describe our initial experience with a new technique for the treatment of type 4a bifurcation lesions (main branch ostial lesion stenosis of the main vessel immediately after the bifurcation, not involving the sidebranch) using a new technique for primary stenting of the main vessel with simultaneous kissing balloon of the sidebranch in an effort to avoid the snowplough effect.
