Postoperative regression of clubbing at an unexpected rate in a patient with aortic and mitral valve replacement due to infective endocarditis.

Pulmonary diseases such as malignancies, empyema, bronchiectasis, digestive tract malignancies, inflammatory bowel diseases, cyanotic congenital heart diseases and infective endocarditis can cause clubbing. We present a 63-year-old female patient with infective endocarditis, who had clubbing that resolved very rapidly after cardiac surgery due to rupture of the mitral papillary muscle. She had persistent fever and in her echocardiographic examination rupture of the papillary muscle of the anterior mitral valve and significant aortic regurgitation was noted. She was scheduled for emergency operation and had debridement and replacement of the mitral and the aortic valves. During the follow-up, she had complaints of pain in the distal parts of the fingers. The convex shape of the nails changed and basal portions were apparently thinner and paler than the previous thickened and discoloured, hyperkeratotic nails. This newly growing tissue rapidly replaced the old thick nails in 3 days.
