Problems in the diagnosis and surgical treatment of pulmonic stenosis with intact ventricular septum.

چکیده
Obstruction to pulmonary blood flow may occur in the pulmonic valve, in the infundibulum or in both. Cardiac catheterization aids in the determination of the site of obstruction. Criteria for the differentiation at operation of valvular and infundibular pulmonic stenosis are enumerated, and the usefulness of accurate pressure tracings during operation is emphasized. The accurate identification of the site or sites of obstruction to pulmonary blood flow is essential to proper surgical management. A correctly selected operation must be carried out in as complete a manner as possible.

Diagnosis and surgical treatment of infants with critical pulmonary outflow obstruction. Study of thirty-four infants with pulmonary stenosis or atresia, and intact ventricular septum.
The records of 15 infants with pulmonary atresia and 19 infants with critical pulmonic stenosis and intact ventricular septum, all under 1 year of age, have been reviewed. Symptoms started earlier and were more severe in the group with pulmonary atresia. All patients showed arterial unsaturation, and many had congestive heart failure. The electrocardiogram was the most helpful tool in different...

متن کاملSevere Pulmonic Stenosis with Intact Ventricular Septum and Right Aortic Arch.
IT HAS BEEN assumed that patients with pulmonic stenosis and a right aortic arch practically always have a ventricular septal defect as well. As a matter of fact, in the differential diagnosis of pulmonic stenosis and right-to-left shunt, the presence of a right aortic arch often was taken as conclusive evidence of a tetralogy of Fallot-type lesion. -3 A review of the literature revealed among ...
متن کاملPulmonic stenosis with intact ventricular septum; treatment utilizing extracorporeal circulation.
Pulmonic stenosis unassociated with a ventricular septal defect of significant size is often a complex abnormality. The stenosis may be valvular, infundibular, or both, and may be associated with an atrial septal defect or even with a small ventricular septal defect. Preoperative studies cannot accurately predict these variations. The surgical approach selected for such patients should permit t...
