We report on a middle-aged woman treated for chronic hepatitis C virus infection with pegylated interferon. Auscultation revealed a diastolic murmur and the peripheral signs of aortic regurgitation. She had shortness of breath on moderate exertion for the past 4 months, which she attributed to her liver disease. Echocardiogram showed a quadricuspid aortic valve with severe aortic regurgitation. She was referred to a cardiothoracic surgeon for aortic valve replacement (AVR). However, she decided against AVR despite detailed counselling, and opted for medical treatment.
