The plaintiff underwent open-heart surgery to remove a mass that was pre-operatively diagnosed as a likely myxoma (tumor) but was post-operatively confirmed to be a thrombus (blood clot).
The plaintiff brought a medical negligence action against the involved cardiologists, cardiac surgeon, and cardiac anaesthetist, alleging they breached the standard of care by failing to diagnose the mass as a clot and treat it medically, and by failing to obtain informed consent.
The Superior Court of Justice dismissed the action, finding that the physicians met the standard of care in their differential diagnosis and treatment plan, as the mass had unusual features suggestive of a tumor and required surgical removal regardless.
The court also found that causation was not established and that informed consent was properly obtained.
