Does resting long axis echocardiography accurately predict thallium perfusion defects in patients with peripheral vascular disease?
Resting ventricular long axis echocardiography can accurately predict fixed and reversible thallium perfusion defects, offering a potential screening tool for myocardial ischemia before peripheral vascular surgery.
