摘要:

The medical problems in the selection of patients for direct-vision reconstructive operations utilizing the pump-oxygenator of the Gibbon type are discussed. The evaluation of the pulmonary vascular changes is one of the most important medical tasks in many cases. The operative risk for such lesions as ventricular septal defect with high pulmonary flow, tetralogy of Fallot, pulmonary stenosis with intact ventricular septum, and atrial septal defect of the partial atrioventricular canal type is constantly decreasing and is 15 per cent or less at the present time. Heart block and cardiac arrhythmias are still, on occasion, serious postoperative complications. During 1 period of 3 months, subacute bacterial endocarditis (Pseudomonas) occurred in 4 patients but it has not recurred since.

摘要:

Daily water metabolism of 21 patients was studied for 3 days after intracardiac surgery and whole-body perfusion. The average obligatory water losses of these patients were approximately 500, 750, and 750 ml. per M.2of body surface per day on the first, second, and third postoperative day, respectively. A simple system, which combines knowledge of the estimated postoperative water requirement with the known daily change in body weight, was devised to manage accurately water metabolism after intracardiac surgery.

摘要:

Each of 21 patients was noted to have a low concentration of water in the serum immediately after whole-body perfusion. This indicated a loss of water either by the patient or the pump-oxygenator. Investigation suggested that the patient, and not the pump-oxygenator, was the source of water loss. Two of the 21 patients had a profuse, short-lived solute diuresis in the immediate postperfusion period. These phenomena are apparently benign and they require no specific treatment.

摘要:

It is the purpose of this communication to present a case of pre-excitation (Wolff-Parkinson-White syndrome) associated with various arrhythmias, some hitherto not described, and to stress the many features of this unusual case that support the bypass concept of the origin of this syndrome.

摘要:

The diagnosis of Raynaud's disease was suspected in 756 female patients at the Mayo Clinic from 1920 through 1945. The diagnosis was substantiated from the records of the initial examination or from the follow-up data or examination in 474. The clinical characteristics, including diagnostic criteria, clinical course, complications, and sequelae are discussed.

摘要:

Acceleration of impulse formation in the ordinarily subsidiary A-V nodal pacemaker is manifested in clinical electrocardiograms in a paroxysmal and a nonparoxysmal variety. The former occurs as a rule in normal hearts, the latter in pathologic conditions, frequently, but not invariably also causing A-V block. The electrocardiographic and clinical aspects of nonparoxysmal nodal tachycarida were studied in 30 cases and the relative importance of the disturbance was evaluated in 3 conditions in which it is found most frequently, namely, digitalis effect, acute rheumatic fever, and recent posterior wall infarction.

摘要:

Left heart catheterization is proving of increasing importance in the study of a variety of congenital and acquired cardiovascular defects. More than 500 left heart catheterizations have been performed by the transbronchial method without death or serious sequelae. This technic and its usefulness in clinical investigation and in the assessment of valvular heart disease are described.

摘要:

A diverticulum of the pericardium can often be confused with other lesions of the heart and great vessels as well as mediastinal cysts and other masses. Pericardial effusion, sometimes associated with heart lesions causing cardiac enlargement, is a frequent factor in producing diverticular formation. The mode of development of a pericardial diverticulum is better appreciated when certain features of the anatomic structure of the parietal pericardium are understood. Two cases of pericardial diverticulum that illustrate the etiologic, clinical, and roentgen features of the lesion are presented.

摘要:

A microscopic study was made of the lungs of 18 patients with congenital malformations of the heart in which there was obstruction of pulmonary venous drainage. Alterations in various components of the pulmonary vascular bed and of the lung parenchyma were described and correlated with the clinical course and the type of malformation present. A quantitative evaluation of the pulmonary arterial thickening was made by determining the lumen:wall ratio of small vessels. The anatomic alterations found in these children were compared to those of adults with acquired mitral stenosis.
