Impact of 3D TEE guided ASD transcatheter closure on procedure outcome and radiation exposure

Abstract

Abstract Background Transcatheter ASD device closure of secondum ASD is widely accepted in closure of ASD. Radiation exposure increases the risk of cancer for both patients and staff members, fusion of 3- D TEE and fluoroscopy has helped us decrease radiation exposure during whole procedure. Aim to assess feasibility of 3 D TEE guidance in transcatheter ASD closure and assess its value in reducing radiation exposure as compared to control patients. Methods This study was conducted on 30 patients with secundum ASD referred to cardiology department - Ain Shams University for percutaneous ASD device closure under 3D TEE guidance and 54 control patients who performed percutaneous ASD device closure using conventional method. we calculated total procedure time (min), total DAP (mGy/cm2), (FT) fluoroscopy time (min), total air kerma (mGy), maximum ASD diameter (mm) and we recorded implanted device size and device type for all the patients. Results There was no significant difference between both groups regarding FT, total air kerma, dose area product. Operative time of study group was significantly longer than control group although FT reduced significantly in last case of the study. In the last 10 cases of the study radiation exposure decreases and was significantly lower than control group. Conclusion The Use of 3 D-TEE by well-trained imaging cardiologist on tracking catheter during percutaneous ASD device closure decrease significantly radiation exposure of patients as well as medical personnel.
