Color 2-D Doppler echocardiography combined with pulsed Doppler method was performed in 100 consecutive patients for assessment of catheter-induced aortic regurgitation (AR) before and 48 hrs after cardiac catheterization. All patients used in the present study had no significant AR (<II°) before catheterization. In 91 patients no AR was confirmed pre- and postcardiac catheterization. In seven of the remaining 9 patients, mild AR (I°) was revealed by color 2-D Doppler echocardiography before catheterization, and the grade of AR was unchanged after catheterization. In only two patients who had mild AR before catheterization (I°), the grade of AR was slightly increased following catheterization (I° → II°). They were a 43-year-old man who suffered from coarctation of aorta and a 79-year-old woman with mild calcification of the aortic valve. The incidence of catheter-induced AR was not influenced by the types of catheters used during catheterization, but might be influenced by the aortic valvular organic lesions such as aging-induced change or congenital factors.
