Phonocardiographic analysis of diastolic flow murmurs in secundum atrial septal defect and ventricular septal defect.

چکیده
The presence oflow frequency diastolic murmurs, presumably due to increased flow through the respective atrio-ventricular valves, has been recognized in patients with atrial and ventricular septal defects for many years. The murmur in ventricular septal defect was reported by Laubry and Pezzi in 1921 and emphasized by Wood (1950). A publication from this institute drew attention to this phenomenon in atrial septal defect (Nadas and Alimurung, 1952). The time of onset of this "rumbling" diastolic murmur was of some interest to one of us, and the clinical impression that the "flow rumble" of atrial septal defect occurs relatively early in ventricular diastole has been mentioned (Nadas, 1963). The present study was undertaken to investigate, by

Prevalence and Etiology of Heart Murmurs in 2-24-Months-Old Infants Kerman, Iran
Background & aim: Congenital heart disease is one of the most common malformations at birth that require timely recognition and treatment. The aim of this study was to determine the prevalence and etiology of detected heart murmurs and association between congenital heart disease and heart murmurs. Recognition of murmurs etiology would help us to manage and treat them properly. Methods: In this...
متن کاملIntegrated Percutaneous Atrial Septal Defect Occlusion and Pulmonary Balloon Valvuloplasty
Introduction: Atrial Septal Defect (ASD) is one of the most common congenital heart diseases during childhood. Today, ASD closure is done by occlutech device via cardiac catheterization. ASD repair with transcatheter technique has shown high closure rate. However, coexistence of severe pulmonary stenosis and large defect in atrial septum is rare. When these two problems coexist, the result is i...

Introduction: In this study, we sought to illustrate our experience in urgent surgical management for embolized cardiac septal occlude devices resulting from trans-catheter closure of atrial septal defect and ventricular septal defect. Mathrials and Methods: We retrospectively reviewed four patients aged 2–10 years who underwent urgent surgery due to cardiac septal occluder embolization between...
متن کاملAssessment of left ventricular function in secundum atrial septal defect by computer analysis of the M-mode echocardiogram.
Left ventricular function in 53 patients with secundum atrial septal defect was assessed by computer-assisted analysis of the left ventricular echocardiogram and by cardiac catheterization. The patients were divided into two groups, those younger and those older than 60 years, to investigate the effect of aging on left ventricular function. Cavity size was significantly smaller than normal (p l...
متن کاملEcho-phonocardiographic and contrast studies in conditions associated with systemic arterial trunk overriding the ventricular septum: truncus arteriosus, tetralogy of Fallot, and pulmonary atresia with ventricular septal defect.
Echocardiography was performed in 62 patients--20 with truncus arteriosus, 14 with tetralogy of Fallot, and 28 with pulmonary atresia with ventricular septal defect. Features common in all three groups were: large single systemic arterial trunk overriding the ventricular septum, mitral-semilunar continuity, large right ventricular dimension, and normal septal motion. Indocyanine green contrast ...
