Postoperative responses in 'prepared' child after cardiac surgery.

Postoperative reactions of children and adolescents realistically prepared for cardiac surgery were analysed for acute and long-term responses. No cases of delirium or psychoses occurred in the 60 children while they were in hospital. Fifty sets of parents and children answered questionnaires 6 months to 4 years after operation (36 under 1 year, 8 from 1 to 3 years, and 6 over 3 years) and assessment of these showed only long-term reaction. Evaluation of reactions is presented by age and in detail. The children aged 2 to 7 years had the greatest number of negative reactions and the only long-term reaction also came from this group. Children 8 to 11 years of age had the least number of negative reactions and the highest number of positive gains. Adolescents, 12 to 19 years of age, were often concerned with their body image (wanted to be considered 'well', resented the scar, etc). From the standpoint of emotional stability and after effects, the 8 to 11-year-old group seemed to do best.

Why does a child with a normal heart undergo cardiac catheterization?

Children who have no heart disease at cardiac catheterization have usually been referred because of signs or symptoms on the background of a basal flow murmur. The ECG and chest x-ray are sometimes spurious and may lead to catheterization. Advances in noninvasive testing are helping to screen this population. Only in rare instances should the risks involved with catheterization be taken in a child with a basal flow murmur and no other evidence of heart disease.

Echocardiographic findings in a patient with primary pulmonary hypertension.

This is a report of the echocardiographic findings in a 9-year-old white female with primary pulmonary arterial hypertension confirmed by catheterization and later at autopsy. The reported findings of an absent "a" wave, a flat diastolic E to F slope, and a midsystolic closure of the pulmonic valve were observed. In addition, tricuspid valve prolapse was noted. Prolapse of the tricuspid valve may be part of the mechanism of tricuspid insufficiency in a patient with pulmonary hypertension.

Masked abnormal drainage of the inferior vena cava into the left atrium.

A 6 year old boy with a large atrial septal defect, partial anomalous pulmonary venous drainage and unrecognized anomalous insertion of the inferior vena cava into the left atrium had cyanosis after closure of the atrial defect. Repeat study revealed direct drainage of the inferior vena cava into the left atrium with moderate arterial oxygen desaturation. At repeat operation an unusual positioning of the inferior vena cava was seen. After reopening of the atrial defect, the pulmonary venous and systemic venous drainage anomalies were identified. A Dacron patch was inserted so as to divert flow to the proper atrium. Repeat catheterization 3 months after operation revealed a normal heart with no obstruction; arterial oxygen saturation was normal. The child has continued to do well 3 years after operation.

Serial studies of pulmonary stenosis in infancy and childhood.

Thirty-five children with pulmonary stenosis were catheterized from 1 day to 9 years of age and recatheterized after 2 weeks to 15 years. Right ventricular systolic pressure rose in 24 and the increase was greater in those under than over 5 years old. Pulmonary valve orifice area per square metre of body surface area increased in 12, but did not change in 3, and fell in 17; absolute decrease in calculated orifice area was usually associated with infundibular hypertrophy. Increase in right ventricular systolic pressure with age was thus caused by failure of the valve orifice to grow fast enough to keep pace with the increase of stroke volume. In the whole group, increasingly severe pulmonary stenosis was matched by increasing electrocardiographic evidence of right ventricular hypertrophy. However, in individual patients the electrocardiogram could suggest that right ventricular pressure had decreased when in fact it had risen considerably.

Echocardiography in duchenne muscular dystrophy.

The cardiac function of 36 males with Duchenne muscular dystrophy was evaluated by echocardiography, and the results were compared with the results of other tests of cardiac involvement, including serum creatine kinase isoenzyme evaluation, electrocardiography, chest x-ray, and physical examination of the heart and lungs. Although correlation between the various methods of assessment was not impressive, the echocardiographic technique appeared to be useful in evaluating and following the cardiomyopathy in these patients. Several aspects of left ventricular function were abnormal in most patients, and only two of the 36 had normal left ventricular size and function. Electrocardiographic abnormalities were also apparent in all patients, although the changes were mild in four of the 36. Clinical evaluation, isoenzyme determinations, and chest x-rays have not been useful in assessing cardiac function. The echocardiographic data on these 36 patients are presented in detail and the patients will now be followed sequentially to attempt evaluation of ongoing changes.

Use of saphenous vein allografts for aortopulmonary artery anastomoses in neonates with complex cyanotic congenital heart disease.

A saphenous vein allograft was used to create an aortopulmonary communication in 16 infants with cyanotic congenital heart disease and ductus-dependent pulmonary blood flow. These grafts measured from 3 to 8 mm in diameter and were placed between the aorta and main pulmonary artery in eight patients, between aorta and right pulmonary artery in eight, and between aorta and left pulmonary artery in one (one child had two grafts). Before heparin was used, early in the series, four of these grafts occluded and three of the four infants died during attempted revision. Another infant died early from renal failure. Late mortality has claimed four: one from cerebral hemorrhage, two from hypoxia, and one at open-heart surgery for repair. There are eight late survivors (50%). Most of the allografts were used before small diameter Gore-Tex was available; in more recent patients, 4- to 6-mm Gore-Tex grafts have been used. In our most recent patient, however, the attempt to place a Gore-Tex graft was unsuccessful, but the more pliable saphenous vein graft was readily placed and an adequate shunt obtained. Both the saphenous vein graft and the Gore-Tex have the advantage of providing pulmonary flow without the higher risk of congestive failure or pulmonary hypertension seen in patients with a Waterston or Potts anastomosis. They are easier to perform, require less anesthesia time than the Blalock-Taussig shunt, last as long as the Blalock-Taussig when done under similar conditions, and are easy to take down at the time of total repair.
