Leaflet Free Edge Detection for the Automatic Analysis of Prosthetic Heart Valve Opening and Closing Motion Patterns from High Speed Video Recordings

...The valve orifice area over time, which informs on the opening and closing motion patterns, constitutes a key quality metric for PHV assessment... ...In this paper, we propose a novel orifice segmentation approach for automatic prosthetic heart valves quantitative performance analysis, based on the detection of the leaflet free edges to accurately extract the actual orifice area.
