N2 - Aims: In addition to patients with pure/predominant aortic stenosis (PAS), real-world transcatheter aortic valve implantation (TAVI) referrals include patients with mixed aortic valve disease (MAVD; severe stenosis+moderate-severe regurgitation). We sought to compare TAVI outcomes in patients with MAVD vs. PAS. Methods and results: Out of 793 consecutive patients undergoing TAVI, 106 (13.4%) had MAVD. Patients with MAVD were younger and had a higher operative risk, a more severe adverse cardiac remodelling, and a worse functional status than patients with PAS. Moderate-severe prosthetic valve regurgitation (PVR) was significantly more frequent in patients with MAVD than in patients with PAS (15.7% vs. 3.6%, p=0.003), even after propensity-score and multivariable adjustments. Moderate-severe PVR was associated with increased one-year mortality in patients with PAS (log-rank p=0.002), but not in patients with MAVD (log-rank p=0.27). Eventually, all-cause and cardiac mortality as well as the functional capacity were similar in the two study groups up to one year. Conclusions: A significant proportion of patients referred for TAVI in a real-world registry has MAVD. Moderate-severe AR at baseline can influence the rate and modify the clinical sequelae of post-TAVI PVR. Eventually, clinical outcomes in patients with MAVD are comparable to those in patients with PAS in the acute and midterm phases, in spite of a baseline higher risk. MAVD should not be considered a contraindication for TAVI
