Objective: Aortic interleaflets triangles annuloplasty (AITA) reduces interleaflet triangles' circumferential extent through properly placed sutures. To achieve aortic root functional unit (ARFU) stabilization, we aimed at quantifying the effect of suture extent (SE) on aortic valve function and at

In-body tissue, architecture technology represents a promising approach for the development of living heart valve replacements and preparation of a series of biovalves. To reduce the degree of regurgitation and increase the orifice ratio, we designed a novel mold for a type VI biovalve. The mold had

Annals of Thoracic and Cardiovascular Surgery 17(2), 153-159, 2011
… Objective: The aim of this study was to determine the impact of patient-prosthesis mismatch (PPM) after mitral valve replacement (MVR) on the late clinical outcome, evaluated from the referred value and measured mitral valve area in the echocardiograph. … Exclusions were patients who had a repeat MVR or concomitant aortic valve surgery. …

… In such a control system, an actuator and a driving device such as a control valve are mounted on the human body. … In this condition, the size and weight of the control valve become serious problems. … At the same time, the valve should be operated with lower energy consumption because of using a limited electrical power. … The typical electro magnetic solenoid valve drives its spool using a larger solenoid to open the valve. …
