A 30-year-old male presented to our hospital with signs and symptoms of biventricular failure. He had no significant past medical history. However, he reported having been stabbed in the chest 18 months prior to the development of symptoms. He was stabbed with a screwdriver-like implement and underwent primary suturing of the superficial wound and insertion of an intercostal drain at a peripheral hospital at that time. During assessment at our hospital, we determined that the cause of the heart failure was severe mitral regurgitation through a 1 cm defect in the anterior mitral leaflet (Panels A and B). There was no evidence of a pericardial effusion or a ventricular septal defect. Three-dimensional transoesophgeal confirmed a well-circumscribed defect measuring 1.2 × 0.9 cm (Panels C and D; Supplementary data online, Videos). This case highlights the importance of a thorough cardiology assessment in any patient with a stab chest in the proximity of the heart and the need for later examination as cardiac sequelae of trauma to the heart may present much later than the initial traumatic event. Furthermore, this case highlights the usefulness of 3D echocardiography in better delineating traumatic cardiac lesions.
