High-Resolution Transthoracic Echocardiography of the Left Anterior Descending Coronary Artery: A Novel Noninvasive Assessment of Coronary Vasoreactivity

HRTTE is able to detect the LAD coronary artery vasodilating effects of NTG and salbutamol and correlates with peripheral vascular reactivity to these vasodilators. This approach provides a useful tool for the noninvasive assessment of coronary vasoreactivity.
