Background: Gerbode's defect is a rare type of congenital defect which permits shunting from the left ventricle to the right atrium. It can either be congenital or acquired. Diagnosis can be made by non-invasive echocardiography.
Case Presentation: We report three cases in our institution who had a congenital type of ventriculoatrial communication. Clinical and echocardiographic findings were reviewed and described. All cases were identified as having a true or direct Gerbode defect. One case was an isolated defect while the other two were accompanied with a patent ductus arteriosus with valvar pulmonic stenosis respectively. Two cases were identified with the use of both transthoracic and transesophageal echocardiogram to confirm its presence in addition to other concomitant abnormalities.
Conclusion: Gerbode's defect is a very rare congenital anomaly which can occur in isolation or may accompany other congenital heart defects. It may complicate these conditions and even lead to misinterpreted diagnosis. These cases underlie the importance of integrating sound clinical assessment as well as meticulous echocardiographic investigation in order to properly diagnose this unusual anomaly. These findings are important most especially in planning surgical repair.
