Purpose: Endarterectomy-free long onlay-yama anastomosis technique is another technique that provides blood flow in common and severe coronary arterial lesions, especially to the branches of the front-down artery (LAD) septal perforator. In this study, we studied the effectiveness of the coronary flow reserve (KAR) measurement with postoperative transistoric ecocardiography in patients with long segment onlay-yama anastomosis of endarterectomy. Tools and Methods: With the application of endarterectomy-free onlay-yama anastomosis technique, 56 patients with coronary bacterium were evaluated postoperative with transstoresic ecocardiography for the measurement of CO, representing the maximum hyperemia rates provided both during rest and with dipiridamol. Thro the long anastomosis line, the LAD-LIMA medium and distal flow patterns were studied, the pic sistolic and diastolic flow speeds and the diastolic speed time integrals were recorded. Results: The average onlay-yama length was 2.97±0.72 cm. When the correlation of changes in the coronary flow reserve (normal values: CFR>2, n: 49 and low values: CFR<2, n: 6) and other ecocardiographic findings was assessed, there was a statistically meaningful reverse correlation between the onlay-yama anastomosis length and the CFR for all patients (respectively 2.97±0.72 cm; 2.35±0.56 m/s; P value: 0.008). A patient with CFR<2 was carried out a coronary angiography. Angiography showed anastomosis after segment with 80% depletion. Result: We believe that the endarterectomy-free onlay-patch anastomosis technique is reliable and can be used in postoperative tracking of patients with coronary bacteria with transtoral ecocardiography.
