Ascites is a rare sign of aortic valve disease. Here, we report two cases of refractory ascites that had resulted from aortic stenosis and insufficiency and consequently improved after aortic valve replacement. The first case was a 44-year-old female who had undergone aortic valve repair for aortic stenosis 15 years earlier. She complained of dyspnea and severe abdominal distension due to unimproved massive ascites despite medical therapy. She was diagnosed with aortic stenosis and insufficiency and functional tricuspid insufficiency as well as complete atrioventricular block. She underwent mechanical aortic valve replacement, tricuspid annuloplasty and DDD pacemaker implantation. The second case was a 61-year-old man with a history of alcoholic liver disease who had been hospitalized for massive ascites, progressing rapidly in spite of aggressive medical therapy. Echocardiography revealed severe aortic stenosis and insufficiency; thus, he underwent bioprosthetic aortic valve replacement. Both patients were completely free from ascites about 6 months after surgery.
