Small Ventricular Septal Defect
نویسنده
چکیده
T HE auscultatory and phonocardiographic characteristics of ventricular septal defects have been the subject of several studies,'-5 none of them dealing specifically with the features of small defects. The present study represents an attempt to define the phonocardiographic pattern of ventricular septal defect with a small left-to-right shunt and normal pulmonary artery pressure. It was hoped that this might provide the clinician with a means of differentiating the murmur of a small ventricular septal defect from the " innocent " or " functional " murmur and from the murmur of mild infundibular pulmonic stenosis.

Herein, we present the case of a 10-year-old child suffering from right-sided infective endocarditis with ventricular septal defect. Echocardiography revealed multiple rare large vegetations on the pulmonary valve extending into pulmonary artery along with a large vegetation over the septal leaflet of the tricuspid valve.

When the pulmonary stenosis is mild, whether the ventricular septal defect is small or large, a left-to-right shunt is always present, giving the clinical picture of a ventricular septal defect. On the other hand, if the stenosis is severe and the ventricular septal defect ...
متن کاملSmall ventricular septal defect associated with severe pulmonary hypertension.
A small ventricular septal defect in an 18 year old man was shown by serial cardiac catheterisation to be associated with a progressive increase in pulmonary arterial pressure. Surgical closure of the defect had no effect on the increased pulmonary arterial pressure. Whether pulmonary hypertension occurred secondary to the haemodynamics of the ventricular septal defect or as an independent even...
