2-1. Case History and Examination
An 82-year-old woman with hypertension visited our hospital with abnormal electrocardiogram findings during a regular medical check-up. Although the patient was asymptomatic, detailed tests were scheduled for suspected ischemic heart disease.
She had undergone Halsted radical mastectomy for left breast cancer at the age of 32 years and cholecystectomy for cholelithiasis at the age of 53 years.
She had no history of infectious diseases, such as syphilis, tuberculosis, or infectious endocarditis, and no history of trauma or inflammatory diseases such as aortitis.
Electrocardiography revealed a heart rate of 50/min, regular sinus rhythm, non-specific QS complexes in V1,2, and ST depression in V4,5,6.
Further, echocardiography revealed a left SVA. No asynergy was observed, the ejection fraction was 73%, and moderate aortic regurgitation was observed.
Computed tomography (CT) angiography confirmed the presence of a saccular left SVA measuring 50 × 48 × 45 mm. A small mural thrombus was observed in the aneurysm (Figure 1). Furthermore, extrinsic compression of the left anterior descending artery was observed, and approximately 50% stenosis was noted (Figure 2).
