Abstract
We conduct the study to assess device position, cardiovascular structure and
morphology in patients who underwent transcatheter closure of atrial septal defect
(ASD).
METHODS:
Electron-bean computerized tomography (CT) was performed in 31 patients who
had undergone transcatheter ASD closure in this institution. The interval between
ASD closure and CT imaging study ranged from 6 months to 3.3 years. Of the the 31
patients, Sideris device was deployed in 7, Starflex device in 10 and Amplatzer device
in 14 patients. Three-dimensional reconstruction of the CT images was performed to
evaluate the device position, patency of systemic and pulmonary venous pathway and
morphology atrioventricular valves.
RESULTS:
Partial obstruction of a pulmonary vein was observed in 4 patients (2 with
Sideris device, 1 with Starflex device and 1 with Amplatzer device). Migration of one
arm to a pulmonary vein was observed in 1 with Sideris device. Migration of one arm
to inferior vena cava was found in one with Sideris device. Impingement on
atrioventricular septum by one arm of Starflex device was found in 1. One had one
arm of Starflex device penetrating atrioventricular septum. One had residual shunt.
None had systemic vena cavae or coronary sinus obstruction. None had impingement
of device on mitral or tricuspid valve leaflets. Cross-sectional and Doppler
echocardiographic studies in the 31 patients showed none had significant pulmonary
or systemic venous pathway obstruction. A small left ventricle to right atrial shunt
was found in the patient who had impingement on the atrioventricular septum.
Trivial-to-mind residual shunt was found on the echocardiogram in 4 with Sideris
device.
CONCLUSION:
CT images can be useful in the assessment of device position and systemic and
pulmonary venous pathway in ASD patients following transcatheter closure.
