GW24-e2150 The value of colour doppler echocardiography in occlusion of elderly with atrial septal defect

Objectives To investigate the value of colour Doppler echocardiography (CDE) in occlusion of elderly with atrial septal defect (ASD). Methods In total of 64 cases of elderly ASD, observe the location, size and residual edge using two-dimensional echocardiography (2DE), observe the atrial septal colourful shunt bunch flow signal and the heart valve colourful regurgitation bunch flow signal using colour Doppler flow imaging (CDFI) and measure the pulmonary artery pressure using continuous Doppler (CW) before the occlusion. If the patient had atrial fibrillation or multiple ASDs, transesophageal echocardiography (TEE) examination should be used to screen the patients according to the indication of ASD occlusion. During the procedure of occlusion of ASD, 2DE was used to monitor the position of occluder, CDFI was used to monitor residual shunt through the atrial septum and CDE was used to determine the efficacy of occlusion. Results According to the results of CDE, we selected 64 cases of elderly ASD, the implementation of all ASD occlusion were successful and the efficacy was satisfactory. Conclusions CDE plays a important role in ASD occlusion. Before ASD occlusion, 2DE is recommedated to observe the location, size and residual edge, CW is recommedated to measure the pulmonary artery pressure. TEE is the key to screen according to the indications of ASD occlusion for the patients with atrial fibrillation or multiple ASDs. All elderly patients with ASD should undergo coronary angiography before the occlusion to exclude the patients with coronary artery disease who can’t treat by stenting.
