Abstract:
Objective To evaluate the feasibility and efficiency of transthoracic echocardiography(TTE) combined with real-time three dimensional echocardiography(RT-3DE)in guiding transcatheter closure of atrial septal defect(TCASD)without X-ray.Methods Eleven patients with atrial septal defects(ASD)underwent the procedure of TCASD guided by TTE combined with RT-3DE.The position of the catheter and transporting sheath,the location and deploying of ASD occluder(ASO)were monitored by muhisection echoscan.especially in RT-3DE.The results were compared with those guided by conventional method(TTE and X-ray).Results All the operations were held successfully.The complications of cardiac tamponade,shedding of occluder,residual shunt,atrioventricular valve regurgitation,embolism and arrhythmia were not observed.Compared with the conventional procedure of the control group,the operation time was significantly prolonged[(65.76±14.15)min versus(45.50±20.88)min,P＜0.000)].Conclusions TCASD was tested to be safe and efficient guided by TTE combined RT-3DE without X-ray,especially for children and pregnant women.It may be expected used widely in the future independently from X-ray.
