Background: The aim of this study was to compare the early results of rapid deployment aortic valves (RD-AVR) and aortic valve neocuspidization (AVNeo) techniques.
Methods: Between December 2019 to May 2022, 104 patients were operated on with aortic stenosis by RD-AVR (N = 52) and AVNeo (N = 52) techniques. Patients with isolated aortic valve stenosis and aortic stenosis concomittant with planned other cardiac surgeries were included.
Results: The mean age of patients in the RD-AVR and AVNeo groups were 67.4 ± 7.8 vs. 62.9 ± 8.7, respectively. Aortic cross-clamp time in the RD-AVR group was 56.7 ± 23.3 minutes, while it was 104.1 ± 27.9 minutes in the AVNeo group (P < 0.001). Cardiopulmonary bypass time in the RD-AVR group and in the AVNeo group was 89.8 ± 27.6 minutes and 141.8 ± 36.7 minutes, respectively (P < 0.001). Permanent pacemaker become necessary in four patients in the RD-AVR group secondary to type 2 AV block. Paravalvular leak was observed in six patients, who underwent RD-AVR, while grade 2 central aortic regurgitation was observed in one patient in the AVNeo group. Hospital mortality was 8% in the RD-AVR group and 6% in the AVNeo group (P = 0.696).
Conclusions: AVNeo procedure is a feasible technique in all age groups of patients with successful hemodynamic results in the early postoperative period and with the advantage of not requiring anticoagulants. It also can be applied with other cardiac surgical interventions.

Background: Rapid deployment aortic valve replacement (RD-AVR) has been recently introduced with encouraging results. Outcomes of isolated RD-AVR include good hemodynamic profile, facilitation of minimally invasive techniques, and reduction of surgical times. However, role of this prosthesis in concomitant surgery is not well known.

Background: We evaluated the incidence, prognosis, and predictive factors of new onset of persistent left bundle branch block (NOP-LBBB) after rapid-deployment aortic valve replacement (RD-AVR).
Methods: This was an observational, retrospective, single-center study of 274 consecutive patients with no baseline ventricular conduction disorder and no previous permanent pacemaker implantation (PPI) who underwent RD-AVR with an INTUITY valve (n = 55) or INTUITY Elite Valve (n = 219) (Edwards Lifesciences). Transthoracic echocardiography and 12-lead electrocardiography was performed preoperatively, at discharge, and at 1-month and 1-year intervals.
