A consecutive series of 50 children undergoing elective operations for ventricular septal defect (VSD) is presented. Atriotomy was performed routinely. Repair of the defect through the tricuspid valve was attempted in all cases and achieved in 72 percent. There was a 24 percent incidence of right bundle branch block. All patients improved symptomatically after the operation. The mortality rate was 4 percent. The right atrial route is considered to be preferable as a primary approach and has no disadvantages.
An assessment has been made of a stereophotogrammetric technique (Beard and Burke, 1967) for measuring and contouring the face. Its contouring capabilities depend on the skin surface texture of the subject. Adults have good skin texture and accurate contours can be drawn. Young children cannot be contoured satisfactorily because they lack adequate skin texture, and only linear measurements can be obtained with precision. The disadvantage of incomplete facial coverage was eliminated by using a pair of oblique exposures instead of the conventional frontal exposure. The need for mechanical head positioning was avoided by use of a sighting device incorporated in the system to orientate each exposure to a common datum.
The clinical findings in 119 children with innocent heart murmurs have been reviewed. The majority were aged between 1 and 5 years, and it was in this age-group also that a maximum incidence of venous hum was recorded. There were no particular ECG or chest X-ray findings.
