Resumen
La insuficiencia de la válvula cardíaca mecánica debido a la fuga del prospecto se produjo en dos pacientes que recibieron prótesis de TRI Technologies. Esta falla de la válvula estructural, causada por la fractura del prospecto, condujo a una parada en el programa de implantación.
Área de la Ciencia:
- Cirugía cardiovascular La cirugía cardiovascular es una cirugía cardiovascular.
- Ingeniería Biomédica Ingeniería Biomédica.
- Ciencia de los materiales Ciencia de los materiales.
Sus antecedentes:
- El escape de folleto es un modo crítico de falla estructural en las válvulas cardíacas mecánicas.
- Informes anteriores documentaron esta complicación en varios diseños de válvulas mecánicas.
- Este estudio detalla dos casos de fuga de folleto con prótesis de válvula de TRI Technologies.
Objetivo del estudio:
- Informar y analizar dos casos de fuga del prospecto en pacientes con prótesis de válvula de TRI Technologies.
- Para investigar la causa de la falla de la válvula estructural en estos dispositivos específicos.
- Evaluar las implicaciones para el uso continuo de las prótesis de válvula de TRI Technologies.
Principales métodos:
- Análisis retrospectivo de pacientes que recibieron prótesis de válvula de TRI Technologies.
- Revisión de los datos clínicos, incluida la demografía de los pacientes, los procedimientos quirúrgicos y los resultados.
- Examen de prótesis explantadas para determinar el mecanismo de fallo.
Principales resultados:
- 36 prótesis de válvula de TRI Technologies fueron implantadas en 34 pacientes entre noviembre de 2000 y febrero de 2002.
- Dos pacientes experimentaron un catastrófico escape del prosthetic leaflet debido a la fractura del sistema de pivote del leaflet.
- Un paciente murió postoperatoriamente, mientras que el otro requirió una reoperación de emergencia.
Conclusiones:
- Las fallas de válvulas estructurales observadas plantean preocupaciones significativas sobre la durabilidad de las prótesis de válvulas de TRI Technologies.
- El alto riesgo de fallo provocó la interrupción del programa de implantación.

01:23Pivot Bearings
2.8K
In mechanical systems, bearings are crucial in facilitating relative motion between two components while minimizing friction and wear. They help distribute various loads (radial, axial or a combination of both loads) across machinery parts, ensuring smooth and efficient operation.
A pivot bearing is a specialized type of bearing designed to support axial loads on a rotating shaft. The bearing surface, or the pivot, is positioned at the end of a shaft to support the axial thrust. The pivot may...

14.9K
The human heart is a complex organ with an intricate system of valves that regulate blood flow. There are two main types of valves: atrioventricular (AV) valves and semilunar valves.
The AV valves prevent the backflow of blood from the ventricles to the atria during ventricular contraction. These valves function with the assistance of the chordae tendineae and papillary muscles. When the ventricles are relaxed, the chordae tendineae are slack, allowing blood to flow from the atria into the...

Mechanical systems are analogous to to electrical networks where springs and masses play similar roles to inductors and capacitors, respectively. A viscous damper in mechanical systems functions similarly to a resistor in electrical networks, dissipating energy. The forces acting on a mass in such systems include an applied force in the direction of motion, counteracted by forces from the spring, a viscous damper, and the mass's acceleration. This interplay of forces is mathematically...

686
Mitral regurgitation (MR) is characterized by retrograde blood circulation from the left ventricle into the left atrium due to inadequate mitral valve closure. The severity of the condition, symptoms, and underlying cause determine treatment strategies.Monitoring and Pharmacological TreatmentPatients with mild to moderate MR typically do not need immediate intervention but regular monitoring to assess progression and guide treatment. Patients with mild MR should have an echocardiogram every 3-5...

Mitral stenosis, a condition marked by the narrowing of the mitral valve, necessitates an integrated approach for effective management. This approach includes preventative measures, medical therapy, and surgical interventions to reduce symptoms and prevent complications.PreventionPrevention of mitral stenosis primarily focuses on reducing the incidence of bacterial infections, particularly streptococcal infections, which can lead to rheumatic fever and subsequent valvular damage.
