[Aortic Valve Endocarditis complicated by Aorto-cavitary Fistula to the Left Atriam Report of a Case].

Aorto-cavitary fistula( ACF) is a rare and serious complication of aortic valve endocarditis, which frequently requires high risk surgical repair. A 78-year-old man under cardioventilatory support was referred to our hospital. Aortic valve regurgitation with ACF to the left atrium, caused by endocarditis, was demonstrated by transthoracic echocardiography. Under ongoing support, surgery was suspended for two weeks after referral, because subacute cerebral infarction was detected. Then we performed aortic valve replacement, mitral valve annuloplasty and closure of the aorto-left atrial communication. The perforation was sutured directly, with glutalaldehyde-treated autologous-pericardium support, on both the aorta and left atrium side. His hemodynamic condition improved dramatically after operation. The patient was discharged from our institute on the 45th-postoperative-day.
