A known case of nephrotic syndrome aged 32 months was admitted to ICU because of loss of consciousness. In physical exam he had tachycardia, tachypnea and hypotension. Lab data showed metabolic alkalosis and hypoxia. In CXR, vascular cut off was seen in right lung and perfusion lung scan showed absence of perfusion in the right lung.Treatment was started with heparin and streptokinase, bu...

Fig. 2. The changes of myocardial ischaemia resulting from steal phenomenon were demonstrated by Thallium-201 myocardial perfusion scan (A-1: pre-embolisation, A-2: post-embolisation). Computed tomographic scan showed that the convoluted fistulous tract, originating from left circumflex coronary artery, passed through the subcarinal and left hilar region. These tortuous fistulae divided into mu...

although thallium-201 exercise scintigraphy has been established for the detection of myocardial ischemia and viability, little is known regarding the myocardial thallium-201 kinetics during angioplasty. herein, we report a 77-year old man with angina pectoris, in whom serial myocardial imaging after a single dose of thallium-201 was helpful in identifying not only the culprit lesion and myocar...

background: early clinical investigations indicate that an infusion of autologous bone-marrow cells into the infarct-related coronary artery is feasible after acute myocardial infarction. there is increasing evidence that cell transplantation may improve the perfusion and contractile function of the ischemic myocardium . the present study reports primarily the safety of intracoronary bone marro...

objective(s): a novel iq-specttm method has become widely used in clinical studies. the present study compares the quality of myocardial perfusion images (mpi) acquired using the iq-specttm (iq-mode),conventional (180° apart: c-mode) and l-mode (90° apart: l-mode) systems. we assessed spatial resolution, image reproducibility and quantifiability using various physical phantoms. materials and me...

Anomalous origin of the left main coronary artery (LMCA) from the right sinus of the Valsalva or the proximal right coronary artery (RCA) is one of the most clinically important anomalies of coronary circulation. We report the case of a patient with chest pain and abnormal thallium myocardial perfusion scan in whom the anomaly was first detected on invasive coronary arteriography. The exact ana...

Exercise-induced ST-segment elevation was correlated with myocardial perfusion abnormalities and coronary artery obstruction in 35 patients. Ten patients (group 1) developed exercise ST elevation in leads without Q waves on the resting ECG. The site of ST elevation corresponded to both a reversible perfusion defect and a severely obstructed coronary artery. Associated ST-segment depression in o...

Acute unilateral pulmonary edema is an unusual clinical condition occasionally associated with severe mitral valve insufficiency. We describe a patient diagnosed as having unilateral pulmonary edema after an acute anterior myocardial infarction. Echocardiograms performed in the acute phase ruled out mitral insufficiency. A perfusion lung scan showed left-sided pulmonary hypoperfusion. The diagn...

background: the implications of cardiac risk stratification before orthotopic liver transplantation (olt) are not well established. we studied the usefulness of myocardial perfusion imaging (mpi) in this scenario. methods: mpi data of 24 patients (9 females), candidates of olt, were collected. they underwent mpi as part of their preoperative risk assessment. mpis were interpreted by 2 nuclear p...

Every day physicians balance clinical information with medical test results when confronted with symptomatic patients. Sometimes they find themselves in an apparently contradicting situation in which a patient has persistent complaints while his or her medical tests are normal. In this issue of the Netherlands Heart Journal, Yokota et al. addressed this matter in the setting of stable angina pe...
