Percutaneous balloon pulmonary valvuloplasty in children.

This report describes the results and follow-up of 27 patients undergoing pulmonary balloon valvuloplasty at Children's Hospital of Wisconsin where this procedure has been performed since 1985. The valvuloplasty data at catheterization as well as follow-up echocardiograms when available were retrospectively reviewed. For 26 patients, the transvalvar gradient changed from a mean of 72 mm Hg + 5.2 (SEM) to 29 mm Hg + 4.4 (SEM) (p 0.00001) a mean gradient reduction of 58%. No major complications were reported and no patient went on to surgical valvotomy. Follow up echocardiograms were available for 26 patients. Average estimated transvalvar pressure gradients by continuous wave Doppler echocardiography were 28 mm Hg at one day (13 patients), 20 mm Hg at mean 1.5 months (18 patients), 23 mm Hg at mean 8.8 months (12 patients), and 19 mm Hg at mean 26 months (8 patients). Percutaneous balloon valvuloplasty gives good results in nearly all patients with pulmonary valve stenosis.

Syncope with prolonged QT interval.

Four children with syncope had a prolonged QT interval on the electrocardiogram. Neurologic studies were negative. One patient had associated deaf mutism, one had a family history of sudden death and prolonged QT interval, and two had ventricular arrhythmias while being monitored in the hospital. Treatment with propranolol hydrochloride eliminated the syncope in all patients, although the ECGs remained abnormal.

The medical and surgical management of patients with congenital heart disease. A survey of current knowledge and practices.

Today, techniques for diagnosis,medical preparation, and definitive surgical repair are available for most cardiac anomalies, if needed. These permit successful treatment and carry a low mortality. Such children can now be expected to lead normal and meaningful lives as contributors to society. When serious symptoms occur in infancy, as discussed herein, an emergency exists and prompt diagnosis and treatment are mandatory for survival.
