Extensive right coronary artery thrombosis in a patient with COVID-19: A case report

Figure 5 Intravascular ultrasound images from two angles. A: Right coronary artery (RCA) in the conventional left anterior oblique projection; B: RCA in the cranial left anterior oblique projection; C: An incipient plaque; D: A concentric plaque-causing moderate luminal stenosis; E-H: A subacute-appearing thrombus with a layered light to dark-gray appearance with white patches and less clear delineations. Moderate-to-severe signal attenuation may also be observed, likely due to the deviation or absorption of ultrasound waves by the subacute thrombus; I: An acute thrombus (asterisk) with a bright appearance, clear outline, and no signal attenuation; J: Discreet intimal thickening.
