    Abstract:
    To assess a possible mechanism of abnormal interventricular septal motion following cardiac surgery, 16 patients were studied during cardiac surgery by M-mode and two-dimensional echocardiography. All 16 patients underwent open heart surgery using cardiopulmonary bypass. M-mode echocardiogram and short-axis views of the left ventricle by two-dimensional echocardiography were obtained before and after pericardiotomy, and before and after the closure of the pericardium. Interventricular septal motion did not change after pericardiotomy. Interventricular septal motion just after cardiac surgery was variable and dependent on each underlying condition. In all the 16 patients, interventricular septal motion became abnormal after the closure of pericardium. The abnormal septal motion persisted following the chest closure. We conclude that pericardial closure is responsible for post-operative abnormal septal motion.
