“…Excursion is technically easier to measure but can overestimate the degree of ischemia. 10 Compared with endocardial excursion, systolic wall thickening better correlates with the degree of ischemia but is more difficult to assess, especially when the epicardial border is not well defined. Importantly, severely ischemic and thus akinetic regions do not thicken during systole but still move by virtue of their physical connection to contiguous regions that have retained contractility.…”

“…Wall thickening is a more accurate measure of regional function than wall motion. 15,25 In addition, short-axis sections can be analyzed at multiple apex-to-base levels, thereby providing the important three-dimensional information not available by contrast radiography. There are several potential problems with this particular method, however.…”

Left ventricular aneurysm (LVA) remains a poorly understood entity, often resulting in congestive failure that is not consistently improved by standard resection with linear closure. Although other surgical approaches have been proposed, current methods to assess their effect on left ventricular function are not adequate. The purpose of the present study was to quantitatively define regional systolic function in patients with LVA and to assess acute changes in regional function after standard repair. Seven patients underwent resection of an anteroapical LVA. Intraoperative two-dimensional echocardiography was performed off cardiopulmonary bypass immediately before and after resection. In all patients, short-axis views at the papillary muscle (apex) level showed anteroseptal paradox and distorted geometry, whereas at the mitral valve (base), symmetric wall motion and geometry were preserved. Videotaped echo images were divided into octants by a floating axis fitted to internal landmarks. Myocardial area and midwall perimeter were obtained for each octant, and wall thickness was calculated at end diastole (ED), isovolumetric systole (IS), and end systole (ES). Wall thickening (A t) for each segment was calculated as the percent increase in thickness from ED and averaged for all seven patients. At the apex level before resection, isovolumetric thinning occurred in the aneurysm as well as bordering segments, with A t ranging from -17 + 5% (+SEM) in the anteroseptal segment to 12+±6% posterolaterally (p<0.05). The isovolumetric bulge was followed by late-systolic thickening, however, with A t ranging from 13 7% to 27+± 8% (NS). Systolic function at the base was symmetric, with A t ranging from 12 ±+3% to 18 ±+3% at IS (NS) and from 20 6% to 26+± 6% (NS) at ES. After resection, isovolumetric function at the apex improved significantly, with thickening present in all segments. In the posteroseptal segment, A t improved from -6±+3% before repair to 11±6% after repair (p<0.05) and improved in the septal segment from -8 4% to 9 + 5% (p

SUMMARY The effects of coronary artery surgery on left ventricular performance were assessed serially by echocardiography and treadmill exercise testing in 54 patients. Patients were assessed one day before operation and again before patients left hospital (mean 10 days after operation) and one month and six months after operation. At the predischarge assessment, 41 (77%) patients showed new abnormalities of left ventricular segmental wall movement, chiefly anteroseptal hypokinesia with hyperkinesia of the posterolateral segment. Although there were no significant changes in anteroseptal wall thickening after operation, there was a significant increase in posterior wall thickening at all postoperative assessments. The frequency of this abnormality decreased progressively after operation; it persisted in 19 (35%) patients at six months. Left ventricular fractional shortening decreased after operation and at one month was significantly less than before operation. There were no significant changes in left ventricular diastolic diameter during the study. Haemodynamic function during exercise, the duration of exercise, and features of reversible myocardial ischaemia all improved progressively and significantly after coronary artery surgery.Abnormalities
