| Mitral regurgitation caused by papillary
muscle rupture has a poor prognosis and should be operated on
soon after onset. We recently encountered a patient who was operated
on 8 months after the onset of mitral regurgitation caused by
rupture of the posterior papillary muscle. The patient was a
72-year-old man who was admitted as an emergency case for acute
left heart failure due to severe mitral regurgitation. As medical
treatment was effective, he refused to have mitral valve surgery.
Six months later, he was admitted to our hospital complaining
of nocturnal orthopnea and underwent surgical treatment. Severe
mitral regurgitation with postero-medial papillary muscle rupture
was revealed by transesophageal echocardiography. Coronary angiography
showed 90% stenosis of the proximal left circumflex artery. At
8 months after the onset of mitral regurgitation, the patient
underwent successful scheduled mitral valve replacement together
with coronary artery bypass grafting. There are few reports of
mitral valve surgery being performed successfully for papillary
muscle rupture due to coronary artery disease in the chronic
stage. Jpn. J. Cardiovasc. Surg. 29: 351-353 (2000) |
