Rats with chronic heart failure (CHF) develop increased myogenic constriction in mesenteric resistance arteries. Here we investigated increased myogenic constriction in relation to alterations in EDHF- and NO-mediated dilatation in CHF-rats. Male Spraque-Dawley rats were subjected to myocardial-infarction or sham-surgery. At 9-10 weeks after surgery, isolated mesenteric artery ring preparations...

BACKGROUND Balloon dilatation of the pulmonary valve remains controversial as a palliative procedure in tetralogy of Fallot. AIMS To determine the clinical outcome, growth of the pulmonary vascular tree and findings at surgery of balloon dilatation of the pulmonary valve performed as a palliation in infants with tetralogy of Fallot. METHODS AND RESULTS Thirty-three severely cyanosed infants...

TO THE EDITOR: We would like to appreciate the interest shown in our article by Dr. Joo. Our response to his queries is as follows: (1) The risk factors for prediction of recurrence after endoscopic pneumatic dilatation are young age, male sex, shorter duration of symptoms, low pre-treatment lower esophageal sphincter (LES) pressure and post therapy LES pressure above 10 mmHg. In the present st...

introduction: abnormal uterine bleeding (aub) is among the most complex gynecological problems, especially during the middle and old age. the aim of this study was to assess the pathological findings in endometrial curettage samples of abnormal uterine bleeding and the risk factors associated with them. methods: in our cross-sectional study, we included all the referring women with aub complain...

INTRODUCTION The perfusion study (which may be obtained using SPECT or GSPECT technology within six hours of administration of the radionuclide Tc-99m-MIBI) reflects the regional blood supply to the left ventricular [LV] myocardium at the time of radionuclide administration (i.e. at rest, at peak exercise, or at peak vasodilatation), while the values of EF, EDV, and ESV measured using GSPECT ar...

Abstract Angiographic Acute Stent Thrombosis occur in 0.5%–2% of procedures.OCT–PCI or Optimized PCI represents a new approach particularly indicated complex high thrombotic risk lesions, patients at bleeding with need for short DAPT and the treatment vulnerable plaques. Post–stent OCT thrombus finding was defined previous studies as mass diameter ≥250μm attached to stent struts, present until ...

DOI:10.1111/j.1651-2227.2010.01830.x ABSTRACT Germinal matrix-intraventricular haemorrhage and subsequent post-haemorrhagic ventricular dilatation (PHVD) are frequently encountered complications in preterm neonates. As progressive dilatation of the lateral ventricles may be associated with elevated intracranial pressure, ultrasound measurements of ventricular size play a major role in the evalu...
