Abstract

Clinical introduction A 50-year-old hypertensive smoker presented with a typical angina of 2 days duration. An urgent ECG revealed extensive anterior wall myocardial infarction. In view of the delayed presentation, the patient was conservatively managed with heparin. In-hospital echocardiogram showed akinesia of entire left anterior descending artery (LAD) territory with severe left ventricular (LV) dysfunction. He was discharged with a plan for early coronary intervention. However, he presented a fortnight later with acute pulmonary oedema. General appraisal revealed a restless individual who was dyspnoeic and diaphoretic at rest. On clinical examination, the patient was in hypotension with features of biventricular failure. A 12-lead ECG showed QS pattern with persistent ST segment elevation in precordial leads. The chest radiograph demonstrated features of pulmonary oedema, cardiomegaly and bilateral pleural effusion. Creatine Phosphokinase-MB (CPK-MB) was negative. A preliminary transthoracic echocardiography was done (figure 1 and see online supplementary video 1).

Question What is the most likely diagnosis based on the echocardiogram?

  1. LV pseudo-aneurysm with contained rupture

  2. Dissecting intramural haematoma of LV apex

  3. Ventricular apical aneurysm with thrombus

  4. LV non-compaction with prominent ventricular trabaculations
