Abstract:
Objective To study the value of transthoracic echocardiography (TTE) in interventional treatment of congenital heart diseases. Methods TTE was used to identify patients with atrial septal defect (ASD, n=26), ventricular septal defect (VSD, n=23) or ductus arteriosus (PDA, n=16). They received interventional treatment with domestic made nitinol occluder. The TTE was then used to monitor the entire process of the surgery and to assess the effect of the surgery. Results The treatment with indigenous nitinol occluder failed in five patients, including two with ASD, two with VSD, and one with PDA. The other sixty-one patients were freated successfully with the occluder. Once the procedure was completed, those patients were found to have neither abnormal valvular regurgination as shown by TTE, nor any shunt flow around the occluder as shown by both TTE and angiocardiography. One month later, TTE demonstrated that the position of all the occluclers remained stable, and no residual leakage or shunt was detected by TTE in all of the sixty-one patients, and the same results were obtained after three months. However, two days after the surgery, ECG showed that three of the patients with VSD suffered from different degrees of atrioventricular block on the second postoperative day, but they eventually recovered after treatment. The successful rate of the procedure was 93.8% (61/65). Conclusions Transthoracic echocardiography may play an important role at three stages (pre-, during- and after), i.e. to select the most suitable patients before the procedure, accurately identify the location, and release of the occluder at the end of the operation; and finally, it serves as a promising method to evaluate the treatment result in patients during their follow-up period.
