The clinical and angiographic impact of intravascular ultrasound guided stenting of unprotected left main and proximal left anterior descending coronary artery. A prospective randomized controlled study in Egypt

Background: Coronary angiography has some limitations in the proper assessment of coronary artery lesions. Intravascular ultrasound (IVUS) before percutaneous coronary intervention (PCI) can identify signifi - cant stenosis, select the appropriate stent and detect complications. The study aimed to evaluate the impact of intravascular ultrasound on clinical and angiographic outcomes after revascularization by stenting for patients with unprotected left main (ULM) or proximal left anterior descending (LAD) coronary artery disease (CAD). Materials and methods: A prospective randomized controlled study that was carried on sixty patients presented with stable angina or non-ST elevation acute coronary syndrome. Coronary angiography that was carried out at cardiac catheterization laboratory at the National Heart Institute in Egypt revealed signifi cant left main or proximal LAD coronary artery disease. Patients were scheduled for revascularization
