A case of tuberculous endocarditis with acute aortic valve insufficiency and annular subvalvular left ventricular aneurysm

Tuberculous endocarditis is an exceptionally rare disease, and its surgical operation has been reported in only one case. This is a successful surgical report of acute aortic insufficiency caused by tuberculous endocarditis associated with annular subvalvular left ventricular aneurysm (ASLVA) beneath the aortic valve. This patient had acute left ventricular failure and cardiorespiratory arrest and suffered from multiple organ dysfunction and coagulopathy disorder. Urgent surgery was performed to replace the aortic valve with the approximation of ASLVA. Histopathological findings of the excised aortic cusps gave the diagnosis of tuberculous endocarditis, and antituberculous drug administration started on the first postoperative day. Postoperative recovery has been uneventful without relapse of tuberculosis for 7 postoperative years. © 2007 The Japanese Association for Thoracic Surgery.
