WebThe PISA (proximal isovelocity surface area) method has been used, among other useful parameters, for assessing mitral regurgitation (MR) as: a) a specific sign of severity, which would make it possible to distinguish between mild and severe MR when the radius value (R) is 0.4 or >0.9 for an aliasing velocity (Va) of 40 cm/s, and b) a ... WebMr Shaun Robinson, first author and Consultant Clinical Scientist at North West Anglia NHS Foundation Trust, said “We are excited for the publication of the new MV guideline that provides a comprehensive overview of echocardiography in mitral valve disease. With descriptions of two and three-dimensional trans-thoracic, transoesophageal and ...
