ULTRASOUND CONTRAST-ENHANCED STRESS ECHOCARDIOGRAPHY WITH MYOCARDIAL PERFUSION FOR FUNCTIONAL ASSESSMENT OF INTERMEDIATE STENOSIS IN THE LEFT ANTERIOR DESCENDING CORONARY ARTERY IN PATIENT WITH PREMATURE VENTRICULAR COMPLEXE

The presence of the intermediate stenosis (30 to 50% of arterial diameter) according to coronary angiography in patients with premature ventricular complexes often represents a complicated clinical task and requires additional confirmation of myocardial ischemia. The present clinical case demonstrates the opportunities and potential benefits of contrast-enhanced stress echocardiography with assessment of myocardial perfusion in diagnosing the hemodynamic significance of the intermediate lesion of the left anterior descending artery in patient with premature ventricular complexes.

Aim. To compare diagnostic value between standard stress-echocardiography and myocardial contrast stress echocardiography in detection of myocardial ischemia in patients with different severity of coronary artery stenoses. Materials and methods. Myocardial contrast stress-echocardiography and standard stress-echocardiography were performed in 38 patients with coronary artery stenoses over 50% by angiography. Of all lesions 39 were intermediate (5075%) and 33 over 75% stenoses. Fractional flow reserve (FFR) was measured in 12 coronary arteries. During myocardial contrast stress-echocardiography wall motion and myocardial perfusion was assessed. Results. Adequate visualisation increased from 81.6% in unenhanced segments to 96.1% in contrast-enhanced segments. The sensitivity, specificity, and diagnostic accuracy of standard stress-echocardiography and myocardial contrast stress-echocardiography in intermediate (5075%) coronary stenoses were 44%, 83%, 56% and 56%, 94% и 64% respectively compare to angiography. Taking into account the 12 arteries with evaluated FFR, these parameters increased to 52%, 93% и 65% in standard stress-echocardiography and to 68%, 100% and 75% in myocardial contrast stress-echocardiography. In coronary stenoses over 75% the sensitivity, specificity, and diagnostic accuracy of standard stress-echocardiography and myocardial contrast stress-echocardiography were 78%, 88%, 80% and 86%, 100%, 92% respectively Conclusion. Use of contrast-enhanced stress-echorardiography significantly increased the diagnostic value of this method by improving endocardial border visualization and possibilities of myocardial perfusion assessment.

Stress echocardiography is a well-established imaging modality that combines echocardiography with exercise or pharmacologic or electrical stress to diagnose coronary artery disease, assess severity of valve disease and investigate potential viability of the cardiac muscle. In the era of tissue harmonic imaging and ultrasound contrast agents, stress echocardiography has established itself as an accurate technique with diagnostic images obtained in almost all patients.
