title: [Late results of minimally invasive operations of myocardial revascularization].
abstract: Minimally invasive operations of myocardial revascularization (MIMR) are done using usual approaches, but without extracorporeal circulation and cardioplegia. Doing these operations according to indications, there is no difference in early results of these operations and the operations with extracorporeal circulation and extracorporeal circulation (1, 2). OBJECTIVE. To evaluate the late results of minimal invasive operations of myocardial revascularization 1 year after intervention, according to detection of patient's functional class, findings of echocardiography and stress test. Also to compare the results of operations in patient's groups of age up to 65 years old and over 65 years old. MATERIAL AND METHODS. From 88 patients, that underwent minimal invasive operations of myocardial revascularization, 34 patients were checked according to investigation protocol, evaluating functional class, myocardial contractility and stress test tolerance. The late results of two different groups of age were compared (each group includes 17 cases). RESULTS. All patients have survived 1 year after operation. Findings of stress test showed, that 60% of patients have reached 100 W and more strain tolerance. Pectoral angina was detected in 12% of cases. There was no difference, that was improved statistically in findings of myocardial contractility before and after operation. CONCLUSIONS. Evaluating the late results of minimally invasive operations of myocardial revascularization (1 year after operation), we can consider, that these operations, that were done according to indications, are improved, safe and suitable also to elderly patients.
