Congenital heart disease; comments regarding incidence and natural history.

The incidence of congenital heart disease is approximately 1 per cent of all live births. Approximately 60 per cent of patients who die of congenital heart disease do so at less than two years of age. Very few patients with such lesions live beyond 45 years at the very most. In about 70 per cent of patients who are born with cardiac anomalies, the lesions are either of kinds that are already being operated upon successfully or for which operations are now being attempted and often are helpful.

Congenital cardiac defects; indications for surgical repair.

The optimum ages for the operative repair of the various congenital defects have not as yet been definitely established. With certain exceptions, it has generally been the authors' preference to delay elective operations until after the age of 18 months. In the usual case, the optimum age for the closure of septal defects is believed to be three to five years. Operative relief of stenosis of the aortic or pulmonic valves, however, is related entirely to the extent of the obstruction, age not being a factor. Although the surgical treatment of coarctation of the aorta is probably best delayed beyond the period of infancy, it is the authors' belief that in the presence of extreme hypertension, cardiomegaly or cardiac failure, early resection of the aortic block should be accomplished. As to the treatment of tetralogy of Fallot, the authors' policy is to delay operation until such time as definitive repair becomes less hazardous. Patients with severe symptoms, however, are given the benefit of some form of operative relief as soon as possible. Whether this is palliative or corrective depends upon the characteristics of the individual case. Definitive diagnostic studies are of great aid in assessing the urgency of operative intervention. The fact that approximately one-third of the patients dealt with required operation at less than 18 months of age suggests that, in selected cases, these studies should be performed early in infancy.

Repair of intracardiac defects; operation under direct vision with the aid of hypothermia or a pump-oxygenator; report of twelve cases.

The repair of intracardiac defects under direct vision by opening the heart to expose the operative field, with the aid of hypothermia or a pump-oxygenator, is now a practical clinical method. Twelve patients were operated upon by this method. In eight patients an atrial septal defect was repaired during total circulatory occlusion under hypothermia. The seven patients in this group who had uncomplicated atrial defects survived the operation and are doing well after a short follow-up period. One patient with an unrecognized, associated ventricular defect died at the time of operation. Four patients were operated upon during total cardiac by-pass with the DeWall bubble-oxygenator. The first three patients survived operation and are continuing to do well after a brief follow-up period. In the fourth patient an atrioventricularis communis was repaired by the reconstruction of an atrial and ventricular septum with a plastic prosthesis. This patient died at the end of operation.

Selective angiocardiography in congenital heart disease.

Angiocardiography has come to be a highly specialized procedure and there are definite indications for doing it. In specific cases it offers clear-cut advantages. Technical improvements permit a single injection of a small amount of contrast substance. Selective angiocardiography is advised where the particular detail of a certain region in the heart is desired.
