A 60-year-old female with a history of hypertension, hypercholesterolaemia, and diabetes mellitus presented two hours after sudden onset of severe persistent chest pain. Electrocardiography showed ST-segment elevation in the inferolateral leads (figure 1A). Coronary angiography revealed a subtotal occlusion of a small left marginal side branch (figure 1B; arrow) and a normal right coronary artery, which could not explain the full typical pattern of apical ballooning as demonstrated by left ventricular angiography (figure 1C and D; arrows).
