[Diastolic murmurs in atrial septal defect (author's transl)].
No correlation was found between the presence of a diastolic murmur in about 50% of patients with artrial septal defect and the calculated shunt volume. A significant correlation was found in respect to the age of the patient, the majority of the murmurs being found in young patients and especially in young patients with tachycardia. Similar murmurs were found in healthy persons and, hence, a functional stenosis of the AV-valve ring could be the reason for this diastolic murmur, which may occur more frequently in patients with atrial septal defect on account of an alteration in the blood stream patterns.
