Neovasc Participates in Round-Robin Study Evaluating In-Vitro Pulsatile Flow Testing of Prosthetic Heart Valves

Company Joined by Other Industry Leaders as Part of ISO Cardiac Valves Working Group


VANCOUVER, July 15, 2019 /CNW/ – Neovasc, Inc. ("Neovasc" or the "Company") (NASDAQ: NVCN) (TSX: NVCN), a leader in the development of minimally invasive transcatheter mitral valve replacement technologies and in the development of minimally invasive devices for the treatment of refractory angina, today announced its participation in a round-robin study evaluating prosthetic heart valve hydrodynamic performance measurements among the 13 leading participating international laboratories.  Aaron J. Chalekian, Neovasc’s Vice President of Product Development & Manufacturing Engineering, was as an author on a recently published paper in Cardiovascular Engineering and Technology highlighting the study.  The paper can be found here:

Hydrodynamic performance testing is one of the core in vitro assessments required by the ISO 5840 series of standards for all prosthetic heart valves. A round-robin study carried out in 2005 in accordance with ISO 5840:2005 revealed significant variabilities in prosthetic heart valve hydrodynamic performance measurements among the participating laboratories. In order to re-examine the interlaboratory variability based on the ”state-of-the-art” under ISO 5840-1 and 5840-2:2015, the ISO Cardiac Valve Working Group decided in 2016 to repeat the round-robin study. 

The ISO Cardiac Valves Working Group consists of one academic laboratory (Helmholtz Institute of the RWTH University, Aachen, Germany), three testing service providers (BDC Laboratories; Medical Implant Testing Lab; ViVitro Laboratories), eight heart valve manufacturers (Boston Scientific; Edwards Lifesciences, Surgical Heart Valve Therapy; Edwards Lifesciences, Transcatheter Heart Valves; Medtronic; Neovasc; Sorin Group Italia s.r.l. (fully owned by LivaNova Plc); St Jude Medical; W. L. Gore), and the Food and Drug Administration Office of Science and Engineering Laboratories.

"We are extremely gratified to be setting the stage for the science in this field, together with such a distinguished group of industry leaders," said Fred Colen, CEO of Neovasc. "This important work will help refine prosthetic heart valve hydrodynamic performance testing.  Neovasc looks forward to continuing to collaborate with the other members of the ISO Cardiac Valves Working Group to achieve further advancements in the design of prosthetic heart valves."

The study revealed improved reproducibility when compared to the previous round-robin study, yet significant variability among different laboratories still exists. It also revealed that prosthetic heart valve hydrodynamic performance testing involves not only ”science,” but also ”art,” especially in the tuning of flow and pressure waveforms. It was determined that it is important to exercise care in the testing by carefully tuning the pulse duplicator system in order to minimize the variations and obtain valid and repeatable measurements. This information allowed the ISO Working Group to incorporate improved language into the ISO 5840-1, -2, and -3 standards that are currently under revision. The results can also be used by the testing laboratories to benchmark pulse duplicator systems, as well as to train and certify testing personnel.
