A 62-year-old woman Underwent percutaneous transhepatic obliteration of a giant portal-systemic shunt. Just after inserting a coil into the shunt, it slipped through the giant shunt and migrated to the right atrium. CT showed coil migration into the coronary sinus.

Background and Purpose-The majority of patients with ventricular wall motion abnormality (WMA) associated with subarachnoid hemorrhage (SAH) are postmenopausal women. In addition to elevated catecholamine, the role of estrogen in the pathogenesis of WMA has recently been implicated. The objective of this study is to clarify the interrelation among catecholamine, estrogen, and WMA in patients with SAH. Methods-A retrospective analysis was performed on the medical records of 77 patients with SAH (23 men, 54 women) whose plasma levels of epinephrine, norepinephrine, and estradiol had been measured and echocardiograms had been obtained within 48 hours of SAH onset. Results-Twenty-four patients (31%) were found to sustain WMA on admission. Multivariate regression analysis revealed that decreased estradiol (P=0.018; OR, 0.902) and elevated norepinephrine levels (P=0.027; OR, 1.002) were associated with WMA. After quadrichotomization of 77 patients based on sex/WMA, plasma norepinephrine levels were markedly elevated in men with WMA, whereas estradiol levels were markedly decreased in women with WMA. Plasma norepinephrine and estradiol levels were not correlated. Fifty-four female patients with SAH were further quadrichotomized based on norepinephrine/estradiol levels with a threshold value of 1375 pg/mL for norepinephrine and 11 pg/mL for estradiol. The incidence of WMA in the high-norepinephrine/low-estradiol group was significantly higher than the low-norepinephrine/high-estradiol group. Conclusions-To our knowledge, this is the first study to evaluate the interrelation among catecholamine, estrogen, and SAH-induced WMA. Lack of estradiol in postmenopausal women may predispose them to develop WMA after poor-grade SAH. However, the precise role of multiple sex hormones in SAH-induced WMA should be evaluated in future prospective studies. (Stroke. 2012;43:1897-1903.)

The purpose of this study is to investigate the effects of renal function and anemia on the outcome of chronic heart failure (CHF). We targeted 711 consecutive patients who were hospitalized at the Division of Cardiology of Fujita Health University Hospital during a 5-year period. The subjects were divided into four groups according to their estimated glomerular filtration rate (e-GFR) calculated using the Modification of Diet in Renal Disease (MDRD) formula. Intergroup comparisons were conducted for underlying heart diseases, clinical findings at the time of hospitalization, treatment, and outcome. Moreover, the patients were divided into two groups according to their serum hemoglobin concentration at the time of hospitalization, using 12.0 g/dl as the dividing point, to study the effects of anemia on the outcome. In the group with decreased renal function, the average age was higher, and ischemic heart disease and associated conditions such as hypertension and diabetes mellitus were observed in most of the patients. In addition, the rate of anemia development and the plasma B-type natriuretic peptide concentration were also high. The greater the deterioration in renal function, the poorer the outcome became (P < 0.0001). Chronic heart failure complicated by anemia showed an especially poor outcome (P < 0.0001). As this study showed that renal function and anemia significantly affected the outcome of CHF, it is clear that the preservation of renal function and the management of anemia are important in addition to the conventional treatments for CHF.
