Natural biomaterials in the management of the aortic valve pathology. Biomedical and clinical aspects: A review.

Heart valve diseases are a prevalent cardiovascular pathology worldwide, affecting nearly 2.5% of the population. Degenerative aortic stenosis is the most common form of heart valve disease.

Complete Aortic Valve Reconstruction with Autologous Pericardium: Analysis of Mid-Term Results of Single-Center Experience with AVNeo Procedure.

Purpose: Aortic valve neocuspidization (AVNeo) is a relatively recent advancement in surgical AV replacement. Data on its performance beyond the short term are limited. We assessed the mid-term outcomes in patients undergoing AVNeo, focusing on feasibility, perioperative details, and its role in AV pathology treatment.

A personalized aortic valve replacement using computed tomography-guided aortic valve neocuspidization. Analysis of mid-term results compared to standard Ozaki technique.

Background: The original Ozaki technique involves sizing the neovalve cusps during cross-clamp. It leads to prolonging the ischemic time compared to standard surgical AVR. Measurements taken on the collapsed Aortic Root (AR) may also be inaccurate.

Computed tomography-guided aortic valve neocuspidization: details of preoperative assessment and surgical technique.

The original Ozaki technique involves sizing and trimming the neovalve cusps during cross-clamp. It leads to prolongation of the ischaemic time, as compared to standard aortic valve replacement. We use preoperative computed tomography scanning of the patient's aortic root to develop personalized templates for each leaflet.

Pulmonary valve neocuspidization and tricuspid valve replacement in intravenous drug abusers with infective endocarditis: Report of two cases.

Right-sided infective endocarditis accounts for 5-10% of endocarditis cases. It occurs predominantly among intravenous drug abusers. The pulmonary valve is involved in fewer than 2% of patients with endocarditis.

[COMPARISON OF LEVELS OF MYOCARDIAL INJURY MARKERS AND THE STATE OF THE OXYGEN BUDGET IN PATIENTS WITH MITRAL INSUFFICIENCY DURING SURGICAL CORRECTION, DEPENDING ON THE METHOD OF CARDIOPROTECTION].

The aim of our study was to compare the levels of myocardial damage markers and the state of the oxygen budget in patients with mitral valve insufficiency during its surgical correction, depending on the method of cardioprotection. We examined 85 patients with mitral valve insufficiency who underwent mitral valve replacement (MVR) surgery and anesthetic management according to the traditional method, the difference was only in the method of cardioprotection. In the I group (n=40) crystalloid cardioplegia (Bernsteinder's solution) was used, in the II group (n=45) - electrical fibrillation of the heart and intermittent clamping of the aorta.
