摘要:

It is generally recognized that interarterial coronary anastomoses of functionally significant size occur with great frequency in the presence of occlusive coronary artery disease and in other conditions such as anemia and cardiac hypertrophy in which myocardial anoxia may be present. Disagreement has been expressed by some investigators regarding the incidence of these anastomoses in normal and abnormal hearts. The problem has therefore been reinvestigated by means of a technic of infusion of saline solution and injection of wax spheres of known size. The results of these observations in 75 hearts are presented and their significance is discussed.

摘要:

The ultimate aim of surgical treatment of Fallot's tetralogy is complete anatomic repair by removal of the obstruction to pulmonary blood flow and closure of the ventricular septal defect. This ideal has been achieved by a small number of surgeons using a pump oxygenator and cardiac arrest. Until it can be realized by all, less complete operations will be performed that will improve the condition without correcting it. Considerable clinical improvement follows infundibular resection by open cardiotomy with or without pulmonary valvotomy. Paradoxically some of these patients may develop a syndrome of heart failure due to the development of a left-to-right shunt through the ventricular septal defect.

摘要:

The clinical applicability of the routine electrocardiogram and the chest roentgenogram in assessing advanced pulmonary emphysema is shown by a correlative study on 150 adults with moderately severe and severe pulmonary emphysema determined by pulmonary function studies. From these data a rather uniform electrocardiographic pattern has emerged entitled "the electrocardiographic pentalogy of pulmonary emphysema" which by itself suggests the presence of an advanced emphysematous state.

摘要:

In complete transposition of the great vessels, survival is possible only when a route of access exists by means of which venous blood may enter the lungs. This report concerns 2 patients in relatively good health in whom a high degree of mixing of venous and arterial blood occurred through an atrial septal defect. The diagnosis was established in both patients by cardiac catheterization.

摘要:

Disproportionately high pulmonary artery pressures and pulmonary vascular resistance in acquired heart disease, particularly mitral stenosis, have been repeatedly observed. Seventeen patients with pulmonary hypertension secondary to elevated left atrial pressure have been studied by the method of temporary unilateral pulmonary artery occlusion: Resistances calculated before and after occlusion showed no change in most cases. The data show that despite very high initial resistance, increase in flow in the lung can occur with rapid reduction in resistance. It is suggested that "tone" of the pulmonary vasculature is operative even at very high pressure levels.

摘要:

The clinicopathologic findings are described in 2 children in whom a localized arteritis of the abdominal aorta had occluded both renal artery orifices to produce hypertension. The relation to primary arteritis of the aortic arch or Takayashu's syndrome is discussed.

摘要:

A simple, reproducible, physiologic technic is delineated for the production and study of thromboembolism. The method is based on the observation that the infusion of serum, in striking contrast to plasma, induces massive thrombosis in vascular segments containing stagnant blood far removed from the site of infusion. Data are presented on the nature of the thrombosis-inducing activity of canine and human serum, on the effect of serum infusions on recipient animals, and on the morphology of the induced thrombus. The adaptability of this method to the study of a variety of thromboembolic phenomena in man is described.

摘要:

Indicator-dilution curves recorded from a systemic artery after injection in the right heart may show the presence of a left-to-right shunt but will not localize it. Injections into the left side of the heart with arterial sampling or into the pulmonary artery with right heart sampling provide accurate and sensitive methods for localization but the technics are inconvenient and sometimes impossible to apply. A simplified indicator method for the localization of left-to-right circulatory shunts is described.
