Diagnosis of endocardial cushion defect with cross-sectional and M-mode scanning echocardiography. Differentiation from secundum atrial septal defect.
Key result
Echocardiography showed discontinuity between the anterior mitral valve and interatrial septum in all 12 cases of endocardial cushion defect, differentiating it from secundum atrial septal defect.

Can cross-sectional and M-mode echocardiography differentiate endocardial cushion defect from secundum atrial septal defect?

Cross-Sectional (n=80)
Structured PICO
Can cross-sectional and M-mode echocardiography differentiate endocardial cushion defect from secundum atrial septal defect?
P
Population
80 subjects including 12 cases of endocardial cushion defect, 20 healthy subjects, 18 cases of mitral valvular disease, 4 cases of congestive cardiomyopathy, 1 case of partial anomalous pulmonary venous drainage, and 25 cases of atrial septal defect of secundum type.
I
Intervention
Cross-sectional echocardiography (ultrasono-cardiotomography, two-dimensional echocardiography, B-scan echocardiography) and M-mode scan along a horizontal section of the heart
C
Comparator
Comparison among different anatomical conditions (endocardial cushion defect, secundum atrial septal defect, normal anatomy, and other cardiac diseases)
O
Outcome
Echocardiographic features differentiating endocardial cushion defect from secundum atrial septal defect and normal anatomysurrogate
Cross-sectional and M-mode echocardiography can reliably differentiate endocardial cushion defects from secundum atrial septal defects based on the continuity of the anterior mitral valve and interatrial septum echoes.
Cite This Study
Beppu et al. (1976) conducted a cross-sectional in Endocardial cushion defect and secundum atrial septal defect (n=80). Cross-sectional and M-mode scanning echocardiography was evaluated on Echocardiographic features differentiating endocardial cushion defect from secundum atrial septal defect and normal anatomy. Echocardiography showed discontinuity between the anterior mitral valve and interatrial septum in all 12 cases of endocardial cushion defect, differentiating it from secundum atrial septal defect.
