A 31-year-old woman suspected to have acute myocarditis was admitted to hospital and was managed with intra-aortic balloon pumping and a percutaneous cardiopulmonary support system because of sustained ventricular tachycardia. After immunoglobulin treatment, cardiac function and systematic inflammation were improved. The left ventricular endomyocardial(More)
Although an autoimmune mechanism has been postulated for myocarditis and dilated cardiomyopathy, immunosuppressive agents had not been shown to be effective. Potential benefits of intravenous immunoglobulin (IVIg) in the therapy of patients with myocarditis and recent onset of dilated cardiomyopathy were reported. Also, experimental studies showed that IVIg(More)
A major limitation of the rotational atherectomy (RA) procedure is the occurrence of the no-reflow/slow flow phenomenon and the optimal strategy is still evolving. Recent clinical studies have demonstrated the beneficial effects of nicorandil, an adenosine triphosphate (ATP)-sensitive potassium channel opener, on no-reflow in patients with acute myocardial(More)
Congestive heart failure developed in a 42-year-old man who had very mild acromegalic features. Echocardiography showed a marked dilatation of the left ventricle and decreased systolic function. Laboratory examinations revealed the elevated levels of growth hormone and insulin-like growth factor-1 and pituitary microadenoma was demonstrated by magnetic(More)
An 86-year-old woman was scheduled to undergo aortic valve replacement and coronary artery bypass graft. On postoperative day 3, she developed sudden-onset neck pain followed by weakness in the right arm. Her symptoms worsened with time, and she developed paraplegia. At 60 h after the first complaint, spontaneous spinal epidural hematoma (SSEH) from C2 to(More)
A simple total anomalous pulmonary venous connection (TAPVC) coexisting with a persistent left superior vena cava (PLSVC) is extremely rare. Connection of the PLSVC with the coronary sinus behind the left atrium induces coronary sinus dilatation. This reduces the free posterior wall space to which the common pulmonary vein is anastomosed for repairing the(More)
We report a case of aortic regurgitation (AR), coronary artery-to-pulmonary artery (CAPA) fistula, pulmonary atresia with ventricular septal defect (PA/VSD), and major aortopulmonary collateral arteries (MAPCAS). As a result of coronary steal and AR, myocardial ischemia and ventricular dysfunction occurred. When the patient was 2 months old with a body(More)
Whereas mobilization of intracellular Ca 2 ϩ stimulates neu-ronal adenylyl cyclase via Ca 2 ϩ /calmodulin, mobilized Ca 2 ϩ directly inhibits adenylyl cyclase in other tissues. To determine the physiologic role of the Ca 2 ϩ-dependent interaction between Na ϩ /Ca 2 ϩ exchange and ␤-adrenergic signal trans-duction in the intact heart, digoxin (0.3 mg/kg) was(More)
