Clinical significance of reverse redistribution on resting thallium-201 imaging in patients with vasospastic angina.
To evaluate the clinical significance of reverse redistribution (RR) of resting 201Tl single photon emission computed tomography (SPECT) in patients with vasospastic angina (VSA), we performed left ventriculography, coronary angiography and resting 201Tl-SPECT in 22 patients with VSA. Left ventriculography showed abnormal wall motion in 17 of 22 patients (77%) and 37 of 154 segments. Thirty-one...
متن کاملEarly redistribution of thallium-201 after temporary ischemia.
To define the time course of redistribution of thallium-201 (201Tl), ischemia was induced in seven pigs by temporary occlusion of the circumflex coronary artery. After 1 1/2 min of occlusion 201Tl and labeled microspheres were injected into the left atrium. Flow was re-established 4 min after occlusion. Prior to reflow, the relative activities of 201Tl and microspheres in the ischemic area were...
متن کاملTime course of thallium-201 redistribution after transient myocardial ischemia.
The mechanism and time course of thallium-201 (201T1) redistribution after transient myocardial ischemia was investigated in 27 anesthetized dogs given 1.5 mCi of 201Tl intravenously 10 minutes after occlusion of the left anterior descending coronary artery. Coronary reperfusion (RP) was accomplished 10 minutes after 2`TI administration. Transmural myocardial biopsies were obtained in situ from...
متن کاملThallium reinjection demonstrates viable myocardium in regions with reverse redistribution.
BACKGROUND The clinical significance and pathophysiological mechanisms of reverse redistribution on stress-redistribution thallium-201 myocardial scintigraphy in patients with chronic coronary artery disease are unclear. Recent studies have shown that thallium-201 reinjection is a useful technique for the detection of myocardial viability in chronic coronary artery disease. In this investigatio...
متن کاملCardiac imaging in syndrome X: the problem of "reverse redistribution'.
patient with cardiac arrest, as initial presentation of the underlying cardiac disease, who receives an implantable cardioverter-defibrillator, cost cannot be evaluated, unless the first line therapeutic option for these patients is not an implantable cardioverter-defibrillator. Another approach could be to randomize these patients to an implantable cardioverter-defibrillator or to other forms ...
