Aortic intramural haematoma (IMH) is an acute aortic syndrome which constitutes 5%–20% of all acute aortic syndromes.[1][1] It is defined as a contained haemorrhage into the media without rupture of the intima.[2][2] It is thought to either be due to rupture from a penetrating atherosclerotic

A 63-year-old man underwent an aortic valve replacement (Carbomedics Top Hat No 23) for a severe aortic stenosis. A tricuspid annuloplasty and closure of an ostium secundum atrial septal defect were also performed. The preoperative electrocardiogram showed a left bundle branch block. There were no significant …

This case report describes the devastating consequences of spontaneous coronary dissection in a 36 year old female patient who otherwise had a normal coronary arteriogram. Intravascular ultrasound showed coronary artery dissection and intramural haematoma at the left main stem coronary artery. Acute coronary syndrome developed and subsequently surgical revascularisation was performed successfully.

Aortic intramural haematoma (IMH) has been considered a precursor of overt aortic dissection; however, the pathophysiologic mechanism, evolution, and prognosis are rather different from classical dissection. Advances in imaging techniques have facilitated diagnosis and have aided understanding of the natural …

Aortic intramural haematoma (AIH), a variant form of aortic dissection, is characterised by absence of intimal tear and direct flow communication between the true and false lumen. Diagnostic criteria for AIH by transoesophageal echocardiography (TOE) include: (1) absence of dissection membrane; (2) no communication between the false and …

The term “acute aortic syndrome” (AAS) has recently been introduced into the literature1 to describe a variety of acute aortic pathologies. These include classic aortic dissection, intramural haematoma, and ulceration of the aorta. Classic aortic dissection is characterised by the existence of an intimomedial entrance tear and, in the majority of cases, a re-entrance tear. Intramural haematoma is characterised by the presence …

A 67 year old man was transferred because of an acute inferior myocardial infarction with thrombolytic treatment. A thallium 201 myocardial scan revealed partially reversible defects in the right coronary artery (RCA). The angiogram performed seven days after the onset of myocardial infarction showed critical tubular narrowing …
