    Summary of the class action

    On October 26, 2016, Mr. Paul-Aimé Paquin filed a class action suit against the Montreal Heart Institute, Livanova PLC and Sorin Group Deutschland GMBH.

    The proposed class includes all people who had open heart surgery during which a 3T thermal generator was used. The use of this 3T thermal generator can lead to an infection with the bacterium Mycobacterium chimaera.

    Livanova PLC is a United Kingdom company that was born from the merger of Sorin S.p.A and Cyberonics Inc.

    On November 2, 2016, the applicant filed a Motion to discontinue his claim against the Montreal Heart Institute and  to change the class description in order to include all persons who had open heart surgery in one of the listed hospitals.

    On May 24, 2018, the Honourable Judge Donald Bisson rendered a judgement authorizing the applicant’s motion to amend the application to be authorized to bring a class action.
