RISInsights From In-Vitro Flow Visualization Into the Mechanism of Systolic Anterior Motion of the Mitral Valve in Hypertrophic Cardiomyopathy Under Steady Flow Conditions
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Hypertrophic obstructive cardiomyopathy is a heart disease characterized by a thickened interventricular septum which narrows the left ventricular outflow tract, and by systolic anterior motion ...
Quantification of Mitral Regurgitation Using Corrected Doppler Measurements

Quasisteady Behavior of Pulsatile, Confined, Counterflowing Jets: Implications for the Assessment of Mitral and Tricuspid Regurgitation
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Mitral and tricuspid regurgitation create turbulent jets within the atria. Clinically, for the purpose of estimating regurgitant severity, jet size is assumed to be proportional to peak jet flow ...
Pulsatile Flow Computational Simulations of Mitral Regurgitation
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The noninvasive quantification of mitral regurgitation remains an important clinical goal. Recently, the flow convergence method was developed to estimate the regurgitant flow rate. This study ...
Design of a Catheter-Based Device for Performing Percutaneous Chordal-Cutting Procedures
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this paper we detail the rapid design, fabrication and testing of a percutaneous catheterbased device that is envisioned to enable externally controlled manipulation and cutting of specific ...
