Abstract
Background: The non-invasive tests like X-ray, ECG and Echocardiography are viewed as an
extension of clinical art in cardiology and have become an integral part of history taking, physical
examination and other diagnostic method.Atrial Septal Defect (ASD) of secundum type is defined as
a through and through communication at atrial level. Previously the diagnosis and decision of
surgery for ASD, mandatorily advocate cardiac catherization.Now cardiologist and cardiac surgeon
very hardly asked for cardiac catheterization. Non-invasive diagnosis with the help of ECG, X-ray
and Echo is sufficient for its diagnosis and treatment for surgery. In Bangladesh there is no study
upon it. Considering this ground the study is perform on Bangladeshi patients.
Methods: Forty six consecutive patients with clinical (auscultatory and electrocardiographic) signs
of uncomplicated atrial septal defect of secundum type were examined by chest x-ray, ECG and
echocardiography, before right heart catheterisation.
Result: Thirty four (74%) had ASD, four patients (9%) had insignificant pulmonary stenosis, and
eight subjects (17%) were normal. No false positive diagnosis of atrial septal defect was made by
chest x-ray examination, whereas increased vascular markings were incorrectly interpreted as
pulmonary congestion in one case. Eight patients had x-ray films showing questionable signs of
left-to-right shunt. Twelve of 30 patients with a large left-to-right shunt were correctly selected for
surgery based on radiological findings.
Conclusion: Analysis of non invasive diagnosis and management of ASD secundum conform the
usually described pattern in western literature.
