BACKGROUND
A sinus of Valsalva aneurysm (SoVA) is a rare cardiac condition caused by the dilation of a coronary sinus. If untreated, it can commonly lead to valvular dysfunction, arrhythmias, or rupture.
CASE SUMMARY
A 71-year-old patient with hypertension and hyperlipidemia presented with an embolic stroke. Multimodality imaging revealed a large, 7.0 cm × 5.6 cm SoVA originating from the noncoronary sinus and causing nearly complete obstruction of the left atrium. The aneurysm was surgically repaired, and the patient made a full recovery.
DISCUSSION
In rare cases, a stroke may be the initial presentation of a SoVA. The probable cause of the patient's stroke was attributed to thrombus formation within the SoVA that embolized.
TAKE-HOME MESSAGES: This case emphasizes the importance of multimodality imaging for the diagnosis of a SoVA and for planning surgical repair. Additionally, clinicians should consider a SoVA in the differential diagnosis for a patient presenting with a stroke.
背景
瓦氏窦瘤（SoVA）是一种由冠状窦扩张引起的罕见心脏疾病。若不治疗，通常会导致瓣膜功能障碍、心律失常或破裂。
病例摘要
一名71岁患有高血压和高脂血症的患者出现栓塞性中风。多模态成像显示一个源自无冠窦的7.0厘米×5.6厘米的大SoVA，几乎完全阻塞左心房。该动脉瘤通过手术修复，患者完全康复。
讨论
在罕见情况下，中风可能是SoVA的首发表现。该患者中风的可能原因归因于SoVA内形成的血栓发生栓塞。
要点
本病例强调了多模态成像对SoVA诊断及手术修复规划的重要性。此外，临床医生在对中风患者进行鉴别诊断时应考虑SoVA。
