The native valve was crossed and the prosthetic aortic valve was properly positioned in all cases and implanted in the correct position. No patient underwent post‐dilatation and trivial AR was present in four patients. There were no adverse events (death, need for pacemaker, myocardial infarction, or stroke). At 30 days post‐procedure, all patients were alive and had significant clinical improvement.</p> </sec> <sec id="ccd24766-sec-0005" sec-type="section"> <title>Conclusions</title> <p>Direct implantation of Edwards SAPIEN XT without prior BV in selected cases is feasible and safe.
