Transcatheter aortic valve replacement (TAVR) is used for the treatment of aortic stenosis (AS). Besides major bleeding, conduction blocks, stroke or atrial fibrillation, complications include cardiac perforation with possible left-to-right-shunts. Herein is reported the sixth case of a left-to-right shunt in an 87-year-old man who underwent TAVR using a 29 mm Edwards SAPIEN S3 prosthesis to treat AS. Soon after the procedure, a small channel evolving from the right coronary cusp could be detected on echocardiography. The patient was managed medically.
