Pectus carinatum.

In the mirror of the pertinent literature, we present our experiences gained in 161 operations for pectus carinatum. The Type I (keel chest) deformity is corrected by bilateral resection of the costal cartilages, transverse osteotomy of the sternum, detachment of the xiphoid process, and resection of the lower end of the body of the sternum. The sternum is maintained in its corrected position by utilizing the pulling force of the rectus muscles through the reattached xiphoid and by tacking the pectoralis muscles together in front of the breast bone. Type II (pouter pigeon breast) is handled by double transverse osteotomy, chiseling off the protuberant portion of the strernomanuberial junction, and by supporting the lower sternal body with either the suspended xiphoid process or with Marlex mesh. Limited forms of Type III (asymmetrical or lateral pectus carinatum) are managed with simple resection of the involved cartilages only. If the anomaly is more extensive, bilateral resection of the cartilages and correction of the sternal axis is carried out.

Sinus venosus type of atrial septal defect with partial anomalous pulmonary venous return.

This report describes our method of repairing the sinus venosus type of atrial septal defects. The superior vena cava is compartmentatlized by means of a single double-armed suture. Caval catheters are used as temporary internal shunts, and a vertical U-shaped patch is incorporated into the atriotomy suture line. The experiences with 27 cases are presented.

Mycobacterium fortuitum epidemics after open-heart surgery.

We present the clinical and epidemiological features of Mycobacterium fortuitum epidemics involving 19 patients who underwent open-heart surgery. The source of the infection could not be identified. However, bone wax and homografts utilized at that time have been suspected. The infected patients responded poorly to antibiotic management and their courses in most cases were influenced beneficially by total sternectomy and transplantation of the omentum into the mediastinum. The emergence of M. fortuitum may represent an aggressive bacterial strain resistant to presently used broad-spectrum antibiotic drugs.

The application of thermography in the study of coronary blood flow.

The technique presented in this paper is based on the authors' previous observations in which they found that artificial decrease of blood flow to a portion of the heart muscle leads to an immediate and proportional drop in the regional myocardial temperature. It appeared to the authors as a logical next step to apply the thermographic camera to a monitor and to record such changes in the human patient during coronary surgery and to use the data to draw conclusions applicable to regional blood supply and to blood flow through surgically inserted vein grafts. They found that, on the normothermic heart, there were well-identifiable "cold" patches corresponding with areas of impaired coronary circulation. By infusion of blood to the ischemic myocardium through individual release of the bypass grafts, the thermogram responded by immediate appearance of "warm" spots corresponding with the areas supplied by the grafts. Even more dramatic demonstration of graft patency and outline of the area supplied by the graft could be performed by injecting cold saline solution into the grafted saphenous veins. In the author's experience this most interesting new method proved to be a useful tool in coronary surgery both as an adjunct in delineating ischemic areas and in proving the patency and efficiency of the grafts inserted.
