The pathology of fresh and cryopreserved homograft heart valves: An analysis of forty explanted homograft valves [PDF]
, 2002 Objective: Tissue degeneration reduces the durability of aortic and pulmonary homograft heart valves. Homograft valves can evoke cellular and humoral immune responses that might be detrimental to the valve tissue.

Clinical periodontal diagnosis
Periodontology 2000, EarlyView., 2023 Abstract Periodontal diseases include pathological conditions elicited by the presence of bacterial biofilms leading to a host response. In the diagnostic process, clinical signs such as bleeding on probing, development of periodontal pockets and gingival recessions, furcation involvement and presence of radiographic bone loss should be assessed prior ...

Cylindrical prosthetic valves for the tricuspid position: prospects and limitations
Вестник трансплантологии и искусственных органовTricuspid valve (TV) replacement for primary regurgitation is a relatively rare procedure. Bioprosthetic valves are generally preferred because they do not require anticoagulant therapy and tend to degenerate more slowly in the tricuspid position than in

Prosthetic heart valves : selection of the optimal prosthesis and long-term management
, 2009 The introduction of valve replacement surgery in the early 1960s has dramatically improved the outcome of patients with valvular heart disease. Approximately 90 000 valve substitutes are now implanted in the United States and 280 000 worldwide each year;
