다국어 초록 (Multilingual Abstract)

A 78 years old woman visited emergency room with dyspnea started 12 years ago and aggravated 2 weeks ago. She had a cardiac operation 17 years ago, that was repair of atrial septal defect secundum type and bioprosthetic replacement of tricuspid valve. Her fingers were cyanotic and clubbing. Electrocardiogram showed atrial fibrillation and incomplete right bundle branch block. Chest X-ray showed marked cardiomegaly and chest CT showed large mass in right atrium and atrial septal defect. Echocardiography revealed thickening of bioprosthetic tricuspid valve with severe tricuspid stenosis and moderate tricuspid regurgitation(fig.1-A). And atrial septal defect with right to left shunt, large thrombus at right atrium were detected(fig.1-B). Her bioprosthetic tricuspid valve was replaced, atrial septal defect was closed by patch and thrombus was removed. After operation cyanosis was disappeared and chest X-ray showed improved cardiomegaly. We report this case successful reoperation in patient with cyanosis because of atrial septal defect with right to left shunt and severe tricuspid stenosis and regurgitation.
