A 62-year-old man was admitted because
of cardiac failure caused by mitral valve regurgitation. After
his cardiac and general conditions had been evaluated, he underwent
an operation. Some of chordae tendineae of both leaflets were
ruptured and both leaflets had deformities. Since his mitral
valve could not be repaired, it was replaced with a 29mm Hancock
II bioprosthesis. Two weeks after operation, transesophageal
echocardiography (TEE) and left ventriculography revealed that
one of the three leaflets of the prosthesis was fixed in the
closed position, and mild mitral valve stenosis without regurgitation
was recognized. But he had no complaints and there were no other
major disorders. He was observed every 2 weeks as an outpatient.
Six months after operation, TEE showed good opening and closing
of all 3 leaflets and showed no major abnormalities, although
the cause of the failure was unknown. He is healthy 2 years after
operation, but is being observed carefully.
