“…They also reported less pressure gradient in patients with AVNeo than in those with AVR. 18 Yoshikawa et al have reported the usefulness of measurements of the aortic annulus diameter using speckle-tracking transesophageal echocardiography. Figure 5 shows 3 measurements during the cardiac cycle.…”

“…Also, studies that compared AVNeo with the aortic valve replacement reported that greater effective aortic valve area and smaller aortic valve pressure gradient pressure were obtained with AVNeo procedure [23] [24]. In addition, aortic annular dimensions after AVNeo were found similar to the dimensions of normal aortic valves [23].…”

Background: Aortic neo-cuspidization (AVNeo) procedure has been adopted by limited centers with the publication of the mid-long term successful results. The aim of this study was to present initial experience of the AVNeo procedure of a single center. Methods: The medical records of 24 patients who underwent AVNeo with or without concomitant cardiac surgery between February 2019 and February 2021 at our tertiary hospital were scanned retrospectively. Results: The mean age of patients was aged 58.21 ± 13.14 years and 16 (66.7%) of them were men. 16 patients were operated on for aortic stenosis (66.67%). Morphology of the aortic valve was tricuspid in 21 (87.5%) and bicuspid in 3 (12.5%) of the patients. Additional cardicac surgery was performed in 13 (54.17%) patients. No patients needed reoperation for bleeding, pacemaker implantations, conversion to classical prosthetic aortic valve replacement, or infective endocarditis. Two patients died due to non-cardiac reasons. Preoperative peak and mean aortic valve pressures improved significantly at 1 st and 6 th months (

“…In terms of valve function, they reported that postoperative echocardiography showed a peak TPG of 15.2 ± 6.3 mmHg at 8 years postoperatively. Other studies have shown that the patients undergoing AVNeo had less TPGs and larger EOA than those with conventional AVR, and that physiological motion of the aortic annulus was preserved after AVNeo [ 23 ]. Moreover, AVNeo has some advantages including large EOA in small aortic valve annulus, and anticoagulation-free postoperative management [ 10 ].…”

Background Aortic valve neocuspidization (AVNeo) has emerged as a promising aortic valve procedure, and is expected to have a larger effective orifice area (EOA) than commercially available bioprostheses. It is, however, unclear which indices could facilitate left ventricular (LV) reverse remodeling after AVNeo. The aim of this study is to verify the impact of global left ventricular afterload on the LV reverse remodeling following AVNeo. Methods Data-available consecutive 38 patients (median age, 77; interquartile range, 72.8–82.0) undergoing AVNeo for severe aortic stenosis were enrolled in this study. Preoperative and the last follow-up echocardiographic data were retrospectively analyzed including the valvuloarterial impedance (Zva), a marker of global LV afterload. Reduction in LV geometry index (LVGI) and relative wall thickness (RWT) were used as an indicator for LV reverse remodeling. Results The Zva reduced in 24 patients (63.2%) during the follow-up period (median, 12 months). Reduction in Zva significantly correlated to improvement of LV geometry (LVGI (r = 0.400, p = 0.013) and RWT (r = 0.627, p < 0.001)), whereas increase in EOA index did not significantly correlate to LVGI (r = 0.009, p = 0.957), or RWT (r = 0.105, p = 0.529)). The reduction in Zva was the multivariate predictor of LV reverse remodeling. Conclusions Low global LV afterload led to significant LV reverse remodeling even after AVNeo, which could achieve better valve performance than the conventional bioprostheses.
