FIELD: medicine, cardiovascular surgery. ^ SUBSTANCE: one should carry out left-hand ventriculography, measure end-diastolic, end-systolic volumes, ejection fraction, ejection fraction of contracting segment. Additionally, one should measure basal-apical size of left ventricle without capturing aneurysm, the largest cross-sectional diameter of left ventricle without capturing aneurysm into ventricular systole and diastole. One should repeatedly conduct ventriculography in left-hand oblique caudal (45 degrees and 50 degrees) projection. One should chooses tactics for operations - myocardial revascularization and dissection of aneurysm without a patch or with patch plasty - by the values of necessary and predicted stroke and end-diastolic volumes. At the value of predicted end-diastolic volume being below the value of necessary end-diastolic one, or the value of predicted stroke volume being below the value of necessary stroke one should carry out myocardial revascularization and dissection of aneurysm at patch plasty. Application of the innovation enables to objectively detect the method of left-ventricular plasty before operation. ^ EFFECT: higher accuracy of prediction. ^ 3 dwg, 2 ex |
