May support TTDE-derived CFVR for ischemia detection in chest pain; hypothesis-generating, needs prospective validation.
Does coronary flow velocity reserve measurement by transthoracic Doppler echocardiography accurately detect myocardial ischemia compared to Tl-201 SPECT in patients with chest pain?
Noninvasive CFVR measurement by TTDE is highly sensitive and specific for detecting myocardial ischemia and identifying ischemic territories in patients with chest pain.
