This case was a 78-year-old woman characterized exertional dyspnea and diagnosed with severe aortic stenosis. Preoperative evaluation revealed that the patient had a very high surgical risk, so transcatheter aortic valve replacement (TAVR) was proposed. But this patient was at high risk of coronary obstruction. After weighing advantages and disadvantages, the heart team decided to choose TAVR under the protection of guide wire and balloon at last. Left coronary ostia obstruction happened after self-expanding valve released during TAVR. Then, emergency “chimney” stent implantation was performed. Finally, TAVR and coronary revascularization was successfully completed. The patient’s condition was improved after TAVR and being good in follow-up. Based on this case, risk factors of coronary obstruction during TAVR and effectiveness and safety of “chimney” stent technique was discussed.
