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 complex

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.
