Abstract:
Tortuous or highly angulated vessels can sometimes be a hindrance to successful percutaneous coronary intervention while conferring an increased risk of major adverse events compared to lesions in nonangulated vessels. We present a case demonstrating the benefit of a recently available deflecting tip 0.014 inch guidewire to help negotiate an acute-angled takeoff of the left anterior descending artery from the left main coronary artery. This novel device proved successful, and as such, can complement the armamentarium of the modern-day interventionalist.
