Abstract：
Aortic root pseudoaneurysm is a devastating complication post aortic valve replacement with a high mortality rate. And dissecting aneurysm into the interventricular septum is a rare variant of aortic root pseudoaneurysm, which is scarcely reported. Multimodal imaging is of great value in its diagnosis and differential diagnosis.
摘要：
主动脉根部假性动脉瘤是主动脉瓣置换术后的破坏性并发症，死亡率很高。解剖室间隔动脉瘤是主动脉根部假性动脉瘤的一种罕见变种，这几乎没有报道。多模态成像对其诊断和鉴别诊断具有重要价值。
