Two vessels, one trigger: simultaneous LAD and CX occlusion in Type II Kounis syndrome

Kounis syndrome (KS) has been defined as an acute coronary syndrome (ACS) triggered by allergic/hypersensitivity reactions induced by various conditions, drugs, environmental factors, foods, and coronary stents.
