Coronary Disease
Comparison Between Optical Coherence Tomography and Intravascular Ultrasound for Intermediate Left Main Coronary Artery Lesions
Significant coronary disease of the left main coronary artery (LMCA) is found in 4%-5% of all coronary angiography procedures. Classically, it has been determined that a significant angiographic stenosis should reach at least 50%…
