Left Ventricular Systolic and Diastolic Functions in Patients With Sickle Cell Anemia
The aim of this study was to evaluate the left ventricular systolic and diastolic functions in patients with sickle cell anemia. Fifty-four patients (34 male, 20 female, mean age 22.6 +/- 7.3 years) and 23 healthy persons (12 male, 11 female, mean age 26.7 +/- 6.8 years) were studied. After clinical examination and routine biochemical evaluation by a hematologist, patients with sickle cell anemia were admitted to the study. M-mode and 2-dimensional and Doppler echocardiographic measurements of patients and controls were performed according to criteria of the American Echocardiography Society. The values of the patient groups were compared with the values of normal healthy subjects (controls). Left ventricular systolic and diastolic diameters of sickle cell patients were greater than those of controls (p < 0.001). All of the sickle cell anemia patients had reduced systolic cardiac function (EF: 0.57 +/- 0.1 vs 0.63 +/- 0.06 and FS: 0.30 +/- 0.06 vs 0.34 +/- 0.04, p < 0.02) and abnormal diastolic left ventricular function parameters compared with the control group (IRT: 114 +/- 20 msec vs 65 +/- 7 msec, p < 0.0001; E/A ratio: 1.2 +/- 0.5 vs 1.6 +/- 0.04, p < 0.01). Left ventricular mass (LVM) was greater in patients than in controls (222 +/- 78 g vs 177 +/- 46 g, p < 0.01). Left ventricular systolic and diastolic functions were abnormal in patients with sickle cell anemia, and the left ventricular mass was greater in the patients compared with controls.

Aorto-left atrial fistula with bicuspid aortic valve and coronary artery origin anomaly.
Published reports of aorto-left atrial fistula are very rare. We report a 20-year-old man who had an aorto-left atrial fistula with bicuspid aortic valve and coronary artery origin anomaly. Because acquired etiologic factors were not detected, we believe that the lesions were structural defects of congenital origin.

Inducible nitric oxide synthase gene expression and enzyme activity correlate with disease activity in murine experimental autoimmune encephalomyelitis.
Messenger RNA encoding inducible NO synthase (iNOS) was measured by competitive reverse transcriptase polymerase chain reaction (cRT-PCR) and ribonuclease protection assays in spinal cords from mice at varying stages of experimental allergic encephalomyelitis (EAE) and from control mice. iNOS mRNA was increased in spinal cords from mice with acute EAE. cRT-PCR assays revealed a 10-20-fold increase in iNOS mRNA in spinal cords during acute EAE compared with the level observed in normal mouse spinal cords. Functional iNOS activity, as assessed by assay of calcium-independent citrulline production, was also significantly increased in spinal cords from mice with acute EAE in comparison to normal controls. The correlation of functional iNOS expression with active disease in EAE in consistent with a pathogenic role for excess NO in this model of cell-mediated central nervous system autoimmunity.

A serious complication of percutaneous mitral valvuloplasty: systemic embolism. How can we decrease it? Case history.
Systemic embolism is a potential and severe complication of percutaneous balloon mitral valvuloplasty (PBMV). The incidence of systemic embolism during PBMV has been reported to be less than 5% and only 0.6% with the Inoue technique. This is less than that reported in closed commissurotomy series and about the same as in open commissurotomy. In the authors' series of 50 cases, the incidence of systemic embolism was 2% (1 case). The patient had mitral restenosis (after closed commissurotomy) with mild to moderate valvular and subvalvular calcification, and cerebral embolism occurred during the procedure. To prevent systemic embolism, the authors' standard policy was to perform transesophageal echocardiography (TEE), computed tomography, and magnetic resonance imaging before the procedure and to give heparin during the procedure and two months preceding it in cases with atrial fibrillation or with a history of previous embolism and to limit manipulation of the catheter in the left atrium. The authors believe that a close scrutiny in the selection of patients, improved technology of the dilating system, good experience with PBMV, and adequate heparinization are also of great importance in the prevention of thromboembolic complications.

Hydatid disease presenting as cardiac tamponade. A case history.
Although hydatid disease has been reported in almost all human tissues, cardiac involvement is uncommon. The authors report a case of cardiac hydatid disease presenting with cardiac tamponade. The diagnostic value of transthoracic and transesophageal echocardiography, computed tomography, and angiography in hydatid heart disease is also discussed.
