• To assess the importance of septal wall motion on patient outcome after resection of large akinetic and dyskinetic segments of left ventricle, the records of 70 patients undergoing left ventricular scar excision alone or in combination with myocardial revascularization procedures between January 1970 and January 1977 were reviewed. Patients requiring simultaneous prosthetic valve replacement were excluded. Preoperative left anterior oblique ventriculograms categorized this series of patients into two distinct groups, group A (36 patients) having normal septal wall motion and group B (34 patients) having akinetic or dyskinetic septal walls. Indications for operation and preoperative ejection fractions were similar in both groups. Analysis of these patients subjected to surgery with and without preoperative evidence of septal wall motion demonstrated no significant difference in either functional clinical capacity or in mortality. Mortality for both groups was 11%. Absence of ventricular septal wall motion has no significant effect on outcome of left ventricular scar resection and should not be used as a contraindication to surgery.
