Abstract: | We report a systolic anterior motion of the anterior mitral leaflet despite employing the sliding leaflet technique for repair
of mitral valve regurgitation. A 65-year-old man with chronic, symptomatic mitral regurgitation due to ruptured chordae tendineae
underwent mitral valve repair by quadrangular resection of the posterior leaflet and sliding leaflet technique with ring annuloplasty.
After weaning from cardiopulmonary bypass, left ventricular outflow obstruction developed and transesophageal echocardiography
demonstrated systolic anterior motion of the mitral valve and severe mitral regurgitation. Non-operative treatment resolved
the outflow tract obstruction, systolic anterior motion and mitral regurgitation. We conclude that post-repair systolic anterior
motion can still occur after the sliding plasty procedure and that medical treatment can successfully resolve systolic anterior
motion and outflow tract obstruction in most patients. |
