Role of multimodality cardiac imaging for evaluation of intramyocardial dissection, from dissecting haematoma to false-pseudoaneurysm: a case series
Abstract
Abstract Background Intramyocardial dissection (ID) is an extremely rare myocardial infarction mechanical complication. Although both clinical and imaging assessment of this rare condition remains a challenge, recent multimodality imaging techniques may help to confirm and to assess the progressive nature of the disease. Diagnosis may be reached in different stages, from as early as the intramyocardial dissecting haematoma to the severe false-pseudoaneurysm. Case summary This series describes five cases of ID and provides insights into imaging findings and clinical course of this extremely uncommon condition. Our patients represented a wide range of clinical stages, from asymptomatic course to cardiogenic shock. The imaging diagnostic approach was very different from case to case and involved techniques such as echocardiography, cardiac CT, and cardiac magnetic resonance. Discussion Intramyocardial dissection is a challenging condition in terms of diagnosis and clinical management associated with high morbidity and mortality. Furthermore, the different nomenclature found in the literature may be confusing. This case series supports the need of a terminology standardization and a multimodal imaging approach, which might be determinant for an accurate differential diagnosis and a suitable therapeutic management.
How strong is the evidence?
Evidence Hub reads this as a case series, done in people. Its evidence level is 5 of 5 (Very low · case / narrative / animal / in vitro / in silico). Case reports, narrative reviews, and animal, cell or computer-model studies give the weakest evidence for human health.
