Stress-Echocardiography with Dipyridamole and Atrial Pacing in Diagnosis of Late Coronary Shunts Stenosis
The aim of the study was to evaluate diagnostic accuracy of stress-echocardiography (stress-еchoCG) with combination of high doze dipyridamole and atrial pacing in diagnosis of late coronary shunts stenosis. 46 men aged from 42 to 63 (48,2 ± 1,8 years), 36 patients undergone mammarocoronary shunting, 10 patients undergone auto venous shunting. Stress-EchoCG with combination of high doze dipyridamole and atrial pacing suggested shunts lesions in 45 patients, in 7 cases previously intact coronary arteries, approved with coronary angiography. Coronary angiographies reviled no coronary lesions in 1 (3 %) patient, in 23 (50 %) patients > 70 % shunts restenosis, in 22 (47 %) coronary stenosis from 40 up to 70 %. Accuracy, sensitivity and specificity of stress-EchoCG with combination of stress-agents in coronary shunts restenosis, as well as stenosis of previously intact coronary arteries were 100 %.
