Coronary angiography and coronary stent implantation are two procedures in one. First, coronary angiography is used to confirm the presence and severity of coronary artery disease, and stent implantation is chosen based on the results of the coronary angiography. Generally, if the coronary angiography results show a stenosis greater than 75% and evidence of ischemia, stenting is recommended. The cost of a coronary angiogram is approximately between$4,000 and$5,000. If a stent is placed and the procedure goes well, the overall cost is approximately between$30,000 and$40,000. These costs include the cost of the procedure; the cost of the guidewire, catheter, balloon, and stent. In the case of complex lesions, more balloons and guidewires may be used and the cost will rise. The costs given so far are approximate and will be determined by the local economy and the pricing of the hospital.
