Fig. 3From: Impact of nodular calcification in patients with acute coronary syndrome (ACS) treated with primary percutaneous coronary intervention (PCI)Post-stent optical coherence tomography (OCT) findings of nodular and non-nodular calcification. Case A. Nodular calcification are associated with small minimum stent area and stent underexpansion (54%). Case B. non-Nodular calcification are associated with good stent expansion (90%).
