Bifurcation Intervention in Single Coronary Artery

Kissing Balloon Inflation Using Guide Extension Catheter and 0.014/0.010-Inch System

Abstract

A 77-year-old man was referred to our hospital for angina on effort. Coronary angiography and computed tomography demonstrated a single coronary artery arising from the right sinus of Valsalva. The left circumflex coronary artery (LCx) anomalously deriving near from the ostium of right coronary artery exhibited severe stenosis in the bifurcation of the obtuse marginal branch. Although the bifurcation lesion still remains a therapeutic challenge for guide extension catheter (GEC)-based percutaneous coronary intervention, under the guidance of intravascular ultrasound imaging, we successfully implanted an everolimus-eluting stent at the bifurcated LCx lesion and performed kissing balloon inflation using 0.014- and 0.010-inch systems through GECs.
