“…A few cases of cardiac conduction disturbance due to the extension of aortitis have been reported (3,4). Watanabe et al (3) and Yokoi et al (4) reported that the possibility of conductance disturbance was caused by a myocarditis-attributable disease. Although coronary ischemia was another possible cause of cardiac conduction disturbance in the present case, a cardiac conduction complication with Takayasu aortitis should be considered in such patients.…”

Late aneurysm formation of Valsalva sinus after aortic valve replacement due to Takayasu’s arteritis

Takayasu's arteritis (TA) is an inflammatory disease of unknown etiology involving the aorta and its branches, and also causes aortic regurgitation (AR). One of the most serious but rare complications after aortic valve replacement (AVR) in TA is aneurysm formation of the sinus of Valsalva. A 64-year-old woman had undergone AVR with a prosthetic valve for AR due to TA 4 years earlier and had received an implanted permanent pacemaker for complete atrioventricular block (AVB) 2 years later. Aortography 4 years postoperatively demonstrated aneurysm formation (47 mm in diameter) at the sinus of Valsalva although preoperative aortography showed severe AR without dilatation of the sinus of Valsalva. We recommended reoperation for the aneurysm but the patient refused. The perioperative histopathological examination revealed extensive destruction of the medial elastic fibers. Both the fragility of the sinus of Valsalva and the residual inflammation could have caused the patient's aneurysm formation. Moreover, extension of TA into the ventricular septum or mechanical compression of the aneurysm against the conduction system might have caused her progressive AVB. Close and lifelong follow-up for patients with TA regarding development of aneurysm after surgical treatment is indispensable when fragility of the aortic root had been confirmed.

We replaced the aortic root in a 43-year-old woman with Takayasu's aortitis associated with prosthetic aortic valve detachment. The patient's aortic valve had been replaced when she was 31 years old with a mechanical prosthesis to treat aortic regurgitation. Though C-reactive protein was kept almost normal with prednisolone, complete atrioventricular block suddenly appeared 12 years after the first operation. After the implantation of an artificial pacemaker, we closely followed up aortic root status. Aortography and echocardiography showed that the valve moved up and down, probably due to enlargement of the sinuses of Valsalva, without perivalvular leakage. We removed the prosthetic aortic valve, which was partially detached from the aortic valve ring at the right- and non-coronary cusps and successfully replaced the aortic root with a mechanical prosthesis inserted into a 26 mm woven graft. Although the postoperative course was uneventful, we closely continue to observe the case and to administer of antiinflammatory medication.
