Structural validation of novel bileaflet mechanical heart valve hinge mechanism - Dylan Goode, Usama Ishtiaq, Dahlia Mohammadi, Hadi Mohammadi, 2025 The structural performance of hinges in mechanical heart valves (MHVs) is essential for durability and reliability. This study evaluates the iValve, a novel bil...

Paige and Mathew are demonstrating the hand tremor attenuator technology to the ENGR 387 class.

Control valves and flow velocity waveforms are closely related. The time-dependent flow velocity is calculated by dividing the volumetric flow rate by the valve's Projected Open Area (POA). On the POA waveforms, dashed ovals mark the moments when the valve closes. The areas highlighted in blue indicate where shock water hammer and transient negative flow velocities occur.

HVPL member: Dr. Dylan Goode, who serves as the lab manager and specializes in the design and testing of medical devices.

HVPL member: Dahlia Mohammadi, undergraduate research assistant, specializing in instrumentation, signal processing, and monitoring.

Meet Dahlia Mohammadi, a second-year student in the Bachelor of Applied Science (BASc) Computer Engineering program at UBC Okanagan’s School of Engineering.

With a passion for computer programming, Dahlia pursued computer engineering and intends on pursuing masters programs in computer engineering and business, with a goal of working for a major tech company.

"After my first year, I came to realize that Engineering is much more than just solving equations and building bridges. There are so many different specializations within the field, and I was fascinated by the wide range of areas where Engineering has a profound impact. It made me truly appreciate how essential Engineering is to the functioning and advancement of society."

Please take a look at our recent publication on flow visualization through mechanical heart valves. This work is the result of a valuable collaboration between the Heart Valve Performance Lab (HVPL) and the esteemed research group of Dr. Kibret Mequanint at Western University.

A novel approach to flow visualization through mechanical heart valves - Dylan Goode, Ruby Dhaliwal, Jaymes Schmidt, Kibret Mequanint, Hadi Mohammadi, 2025 Mechanical heart valves (MHVs) are indispensable in managing valvular disease, yet they often lack the hemodynamic efficiency of native valves and require lifel...
