Successful surgical repair of a huge left ventricular pseudoaneurysm after repair of left ventricular rupture during mitral valve replacement.

A 78-year-old man underwent pericardial patch repair for left ventricular (LV) rupture during mitral valve replacement. After the first operation, a huge (>10 cm) LV pseudoaneurysm was detected, necessitating reoperation. LV rupture is a rare but often fatal complication of mitral valve replacement. Although repair of LV rupture during mitral valve replacement has been reported, the development of pseudoaneurysm after such repair is exceedingly rare. In this case, we successfully treated a huge LV pseudoaneurysm using two pericardial patches to sandwich the rupture hole from the inside.
