How geometry drives innovation in aortic valve repair

Understanding the geometry and thus the possibility of repairing the aortic valve (AV) has evolved over time thanks to the integration of historical insights and technological advances. The aortic root geometry has proven to be central to understanding valve function. Today with modern finite element models and flow studies, supported by four-dimensional magnetic resonance imaging, we have provided a better understanding of the importance of the sinuses of Valsalva in blood flow dynamics, confir
