High-speed-camera recordings and image sequence analysis of moving heart-valves
, 2022 S.169-174Heart valve prosthesis and related reconstruction develop problems during clinical course in patients, due to calcification. To analyse and quantify these effects, heart valves of pigs are filmed during motion using a high-speed camera, whereas ...

Clinical experience with the Bicarbon heart valve prosthesis [PDF]
Journal of Cardiothoracic Surgery, 2007 We have previously reported mid-term results of a study, which ended in January 2000, on the Bicarbon valve. The study concluded that the valve showed excellent clinical results, associated with a low incidence of valve-related complications. In the present study, the same patients were prospectively followed for an additional 5 years.Forty-four ...

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 ...

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;
