Aneurysm of the right sinus of Valsalva after aortic valve replacement in Takayasu arteritis.
We herein report a case with an aneurysm of the right sinus of Valsalva, which developed 14 years after an aortic valve replacement (AVR) for aortic regurgitation caused by Takayasu arteritis. The aortic wall around the right coronary artery ostium showed calcification, as a result, the modified Bentall procedure and coronary artery bypass to the right coronary artery were successfully performed. A pathological study of the resected aortic sinus wall showed a disruption of the elastic fibers in the media, granuloma formation, and a marked proliferation of the collagen fibers in the adventitia, and these findings were compatible with Takayasu arteritis. The development of an aneurysm of the sinus of Valsalva late after AVR indicates the necessity of a close and lifelong follow-up for patients with Takayasu arteritis, especially focusing on the aortic root morphology.
