“…Additionally, in our study we report 2 permanent pacemaker implantations and 7 new cases of left bundle branch block. Ozaki and colleagues 18 and Krane and colleagues 23 reported a lower incidence of conduction abnormalities; however, we performed 9 myomectomies, a well-known risk factor for induction of conduction abnormalities. We also report longer duration of in-hospital stay than usual.…”

“…Whereas root aneurysm is initially limiting, a recent report has shown feasibility and efficacy in root replacement combined with AV neocuspidization (AVneo). 18 Moreover, this technique offers the advantage of using only autologous tissue and also allows attainment of systolic/diastolic root dynamics and effective orifice areas nearly similar to physiologic conditions. 19,20 Therefore, in 2016, after following live cases and dry lab training, we started an AVneo program in our institution.…”

Objectives: Bioprosthetic valve deterioration remains a major limitation following aortic valve replacement. Favorable results have been reported with an autologous pericardium aortic valve neocuspidization.Methods: Seventy patients (31 women and 39 men) (mean age, 62 AE 12 years) with aortic stenosis (n ¼ 52 [74%]) or aortic regurgitation (n ¼ 18 [26%]) underwent the aortic valve neocuspidization procedure. Thirty-four patients (49%) had a tricuspid valve, 35 (50%) had a bicuspid valve, and 1 (1%) had a monocuspid valve. European System for Cardiac Operative Risk Evaluation and Society of Thoracic Surgeons scores were, respectively, 2.2% AE 2% and 2.0% AE 1.8%. Four patients (6%) had active endocarditis and 2 (3%) had endocarditis sequelae. One patient (1%) had fibroelastoma. A combined procedure was performed in 33 patients (46%). Results:The follow-up period was 24 AE 12 months. One patient (1%) died in hospital and 1 patient (1%) underwent conventional valve replacement for significant aortic regurgitation. Postoperative peak and mean pressure gradients were respectively 14 AE 5 and 8 AE 3 mm Hg. Aortic valve area was 2.5 AE 0.6 cm 2 . During follow-up, no patients died. Reintervention occurred in 2 patients (3%). At last follow-up, peak pressure gradient was 13 AE 7 mm Hg, mean pressure gradient was 7 AE 4 mm Hg, and aortic valve area was 2.3 AE 0.7 cm 2 . There was 1 recurrence of moderate aortic stenosis (1%). All patients were in New York Heart Association functional class I (90%) or II (10%). Freedom from major valve-related events was 92.1%, (98.5% for death, 95.2% for reintervention, and 95.2% for endocarditis).

“…Komarov and associates previously reported a Bentall operation using an Ozaki conduit. 10 Most surgeons in low socioeconomic countries create the valved conduit for the RV-to-PA connection either with native or bovine pericardium inside a synthetic tube graft. Due to the high demand for RV-to-PA conduits and very limited supply, we have applied tricuspid Ozaki valved conduits on the right side of the heart for RV-to-PA connection during repair of complex congenital heart anomalies.…”

Various types of autologous materials are used in heart valve surgery, particularly the aortic valve, and this article describes their historical development. The evolution of the use of various autogenous tissues, such as the aortic wall, fascia lata of the thigh, pericardium and others is described and discussed in detail. This paper presents the results of experimental and clinical publications devoted to the surgical techniques and the outcomes of heart valve reconstruction using such materials. The negative aspects of the use of a wide range of autografts are discussed, including the short service life and low strength, which led to declining interest in this group of reconstructive interventions. The method for treating the autopericardium with glutaraldehyde, proposed in 1986 by C.S. Love, J.W. Love and colleagues, raised the use of autologous materials in the reconstruction of heart valves to a new level, allowing surgeons to strengthen the autopericardial flaps and increase resistance to hemodynamic stress. Many surgeons, their interest in such treatment methods increased by this discovery, then reported their observations and further developed ways of using the treated autopericardium in aortic valve surgery. Particularly, the method of neocuspidisation of the aortic valve, introduced into wide practice by M.G. Duran and S. Ozaki, has become the quintessential reconstructive valve surgery involving the use of autologous materials.Received 14 March 2021. Revised 26 April 2021.
