title: [Acquired Left Ventricular-right Atrial Communication due to Infective Endocarditis;Report of a Case].
abstract: A 77-year-old woman presented with a 3-week history of low grade fever, appetite loss and dizziness. An electrocardiogram showed complete heart block. Echocardiography demonstrated severe aortic valve stenosis and a mass of probable vegetation 2 cm in diameter on the atrioventricular septum in the right atrium (RA), but no obvious intra-cardiac fistula. There was no growth of organism in blood cul tures. In the 4th week after admission, a harsh and continuous cardiac murmur was detected for the 1st time. Portable echocardiography revealed disappearance of the mass in the RA, and showed an intra-cardiac shunt from the left ventricle( LV) to RA. The shunt was closed by autologous pericardial patch form LV side and directly with mattress suture form RA side during the emergency operation. The aortic valve was replaced with bio-prosthetic valve (SJM Trifecta 19 mm). No organism was detected in the excised tissue, but antibiotics were continued for 2 months until a permanent pacemaker was inserted.
