Cine magnetic resonance imaging (MRI) was performed on 20 patients (mean age: 5.3 +/- 4.4 years) with atrial, ventricular, or atrioventricular septal defects for evaluation of cardiac structure and blood flow. Prior to cine MRI, electrocardiographically gated MRI using multislice acquisition was performed on all patients to localize optimal slice location.(More)
Newborn infants with intractable respiratory failure who require extracorporeal membrane oxygenation (ECMO) experience diffuse pulmonary atelectasis shortly after initiation of ECMO. Atelectasis is likely due to the primary lung injury and the reduction of applied inspiratory ventilator pressure when the respirator settings are changed to the "rest(More)
Percutaneous balloon aortic valvuloplasty (BAV) was performed in 14 patients, including one critically ill infant with congenital valvular aortic stenosis (AS). BAV was effective in 13 patients (except the infant). The peak systolic pressure gradient between the left ventricle (LV) and the ascending aorta decreased from 76.6 +/- 21.6 to 29.5 +/- 15.3 mmHg(More)

Echocardiography (ECHO) was used to assess the systolic and diastolic cardiac function before and after balloon valvuloplasty (BV) in children with congenital valvular aortic stenosis (AS) or congenital valvular pulmonary stenosis (PS), as compared to age-matched control subjects. BV was performed on each of 7 patients with AS and 9 patients (one patient(More)
The ultra thin walled, two-stage endotracheal tube (UTW-TS-ETT) is very flexible, nonkinking, and has a widened extralaryngeal portion. The UTW-TS-ETT has a greater ID/OD (internal diameter/outer diameter) ratio than a comparable standard endotracheal tube (ST-ETT) because of its thinner wall: 0.2-0.25 mm in UTW-TS-ETT, compared to 0.55-0.8 mm in ST-ETT.(More)
We performed percutaneous balloon aortic valvuloplasty for 10 patients with congenital aortic valve stenosis aged from 2 to 17 years and a 54-day-old infant with critical stenosis. The retrograde single balloon technique was used for 6 patients including the infant; the retrograde double balloon technique was used for 3 patients; and both techniques for 2(More)
The patient was a 27-year-old man who developed spastic quadriplegia and cerebral disorders. Initial signs were gait disturbance, spastic paraplegia, and sphincter disturbance; these occurred when he was 21. Upon autopsy, the white matter of the brain and spinal cord showed diffuse demyelination, and the adrenal glands and right testis were atrophic.(More)
Balloon pulmonary valvuloplasty (BPV) was attempted in 38 cases of congenital pulmonary valve stenosis. It was effective and was done without complication in 36 cases, however it was not effective in two cases of pulmonary valve dysplasia. The balloon used was 20-50% larger in diameter than the pulmonary valve annulus. In the seven cases in which the(More)
