Anthracycline drugs are chemoterapeutic agents highly effective against a wide range of neoplasms. However, its administration may be complicated by cardiotoxic reactions. There is a continuum of increasing risk with increasing total dose of drug rather than an absolute cutoff point for total dose drug of that should not be exceeded under any circumstances. At the present time it appears that a...

Congenital pulmonary valvular stenosis was relieved by percutaneous balloon valvuloplasty during cardiac catheterization on 8 children aged 14 months to 8 years. Before dilatation, the transpulmonary systolic pressure gradients ranged from 33 mmHg to 79 mmHg (Mean:52.00 ± 18.16 mmHg). There were significant reduction in the transpulmonic systolic pressure gradients immediate after balloon dilatation (Mean:17.38±11.16mmHg).
