Transcatheter aortic valve implantation (TAVI) is a novel method for patients with severe aortic stenosis at high surgical risk. Although short- and medium-term outcomes after TAVI are encouraging, long-term data on valve function and clinical outcomes are limited. Hence, our case can make a contribution to literature. An 80-year-old patient with severe aortic stenosis underwent TAVI in our clinic in October 2015. After 5 months, she admitted to our emergency department with severe dyspnea. Her symptoms were started within 2 days and getting worse day by day. Echocardiography revealed us a severe aortic regurgitation due to dislocation of the valve to the left ventricular outflow tract side. After diagnosis, aortic regurgitation was treated by valve-in-valve technique. TAVI may provide an alternative therapeutic approach to ineligible or poor surgical candidates of degenerative aortic stenosis. However, this technique also has some complications such as mortality, atrioventricular (AV) block, stroke, and coronary obstruction. Valve embolization is an another rare complication of this procedure and usually can be prevented by careful preprocedure annulus measurements, stable lead positioning for rapid pacing, optimal valve positioning, full balloon inflation at the time of valve deployment, and complete balloon deflation before stopping rapid pacing. At this point, our case became important for the complication literature with its time, about 5 months. Because it is the more recently used technique, we need much more time to detect the usefulness and complications of TAVI and learn how to avoid these complications.
