A 70-year-old patient underwent
modified maze procedure and mitral repair including quadrangular
resection, annular plication (Reed procedure), and flexible ring
annuloplasty with Cosgrove ring. Systolic anterior motion (SAM)
of the anterior mitral leaflet and mild mitral regurgitation
was observed on weaning from cardiopulmonary bypass. The patient
was medically treated, and postoperative echocardiography revealed
disappearance of the SAM 11 days after surgery. In addition to
the surgical condition of rather excessive annular plication
and small ring, transient conditions including inotropic support,
insufficient volume under diastolic dysfunction of left ventricle,
and loss of atrial contraction were thought to be the causes
of SAM.
