Diagnosis of so-called false aneurysms of the left ventricle after infarction is judged to be important because the risk of rupture is high and resection of aneurysms with a narrow orifice is usually successful. Aneurysms with larger communication orifices are less likely to rupture. Echocardiographic and angiographic criteria have been devised to classify left ventricular aneurysms into two distinct types. In four cases of inferior aneurysms the echocardiographic and angiographic criteria were typical of a "false aneurysm" but the defects were diagnosed as true aneurysms after intraoperative and histological examination. These aneurysms were characterised by their site in the inferior wall and by late diagnosis and treatment, which may have influenced their occurrence and determined the development of their characteristic shape. These findings suggest that the classic echocardiographic and angiographic diagnostic criteria for "false" aneurysms may have to be abandoned.
梗死后左心室所谓假性动脉瘤的诊断被认为很重要，因为破裂风险很高，而且对开口狭窄的动脉瘤进行切除通常是成功的。开口较大的动脉瘤破裂的可能性较小。已经制定了超声心动图和血管造影标准，将左心室动脉瘤分为两种不同类型。在4例下壁动脉瘤中，超声心动图和血管造影标准符合“假性动脉瘤”，但在术中及组织学检查后，这些缺损被诊断为真性动脉瘤。这些动脉瘤的特征在于其在下壁的位置、诊断和治疗较晚，这可能影响了它们的发生并决定了其特征性形状的发展。这些发现表明，可能不得不放弃“假性”动脉瘤的经典超声心动图和血管造影诊断标准。
