Eisenmenger's syndrome is a condition due to any congenital heart defect with an intracardiac left-to-right communication that leads to pulmonary hypertension with reversed right-to-left blood flow and secondary cyanosis. The main complications of Eisenmenger's syndrome are heart failure and arrhythmias. Amiodarone, the drug of choice for arrhythmia treatment in such patients, can cause a numbe...

AIMS This study is the contribution by the Thoraxcenter, Rotterdam, to the European(32)P Dose Response Trial, a non-randomized multicentre trial to evaluate the safety and efficacy of the radioactive Isostent in patients with single coronary artery disease. METHODS AND RESULTS The radioactivity of the stent at implantation was 6--12 microCi. All patients received aspirin indefinitely and eith...

tion has been given to evaluating pulmonary disease using radioisotopic techniques. The majority of the radioactive preparations used for these studies can be divided into two general categories : colloidal aggregates of albumin and radioactive gases. Macro aggregates labeled with 1311or 99@'Tchave been used extensivelyfor determining regional pulmonary per fusion and, as such, are useful for e...

A series of 105 patients treated at least two years earlier with radioactive iodine for thyrotoxicosis have been surveyed. Eighty-five patients (81%) were euthyroid clinically and on the basis of routine thyroid function tests. Of the euthyroid patients 46 (54%) had normal thyroid-stimulating hormone (TSH) levels and 39 (46%) had raised TSH levels. There was no difference in serum triiodothyron...
