Je n'arrive pas à passer mon guide dans la branche fille ; cas clinique et revue de la littérature

Abstract

We present the case of a 53-year-old patient with history of hypertension and dyslipidemia, admitted for effort-induced angina. Coronary angiography revealed two-vessel disease with severe stenosis of the LAD- Diagonal bifurcation (MEDINA 1-1-1). This lesion was considered complex regarding the severe stenosis of the bifurcation core, the angulation <45°, and the severity and length of the diagonal lesion. The procedure was planned according to a TAP technique. The flow in the diagonal was however lost after stenting the main vessel causing an ST elevation with chest pain. It was subsequently recovered using the rescue jailed balloon technique before re-crossing the stent struts of the LAD using a Gaia First® (Asahi) guidewire. The aim of this case report is to illustrate some pitfalls that can be encountered in bifurcation percutaneous interventions and to present technical solutions to solve difficult side branch access issues through a literature review.
