At the present time the treatment of choice for postductal coarctation of aorta is percutaneous angioplasty and stenting. One crucial step for successful stenting of coarctation is accurate positioning of the stent across the lesion, which is difficult due to high pressure blood flow at the site of the coarct. To solve this problem, rapid pacing has been used to decrease cardiac output and blood pressure for a few seconds and prevent excessive motion of the stent during deployment. However, if coarctation is combined with pre-excitation syndrome, rapid atrial/ventricular pacing could cause life-threatening tachyarrhythmias. In this paper, we report a 28-year-old woman with combined coarctation of aorta and Wolf-Parkinson-White syndrome who underwent radio frequency catheter ablation of the accessory pathway and then stenting angioplasty of the coarctation was performed without any complication.
