Mean age was 81.6\u2009\u00b1\u20095.5\u2009years, mean STS score was 6.1\u2009\u00b1\u20093.7. Device success rate was 100%. Aim of the technique was to rotationally deploy the TAVR device with a commissure lying on the bisector between the coronary ostia as calculated on the pre\u2010procedural CT\u2010scan. At post\u2010TAVR CT\u2010scan, coronary clearance was achieved in 98% of patients with no cases of severe coronary artery overlap. In 42 out of 45 patients, THV was aligned or, at most, mildly misaligned; there were 2 cases of moderate misalignment without any case of severe misalignment. Post\u2010TAVR selective coronary artery engagement was attempted and succeeded in all patients (100%).<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>Our CT\u2010scan
