Learning Objectives / Objectifs d'apprentissage:

At the end of this session participants will be able to / Au terme de cette conférence, vous serez:

apply the most recent understanding of the clinical significance of excessive trabeculations of the left ventricle;
review the clinical implications of non-diagnostic Brugada patterns;
assess the QT interval and integrate the elements required for a diagnosis of long QT; and
recognize the indications and pitfalls of provocative tests for Brugada syndrome.

Workshop Description: As the spectrum of diseases referred to the cardiogenetics clinic drastically increases in the current years, we appreciate more and more the risks of overdiagnosis. This workshop will propose a practical approach to conditions where the classification as having or not a disease has some important pitfalls and can have dramatic consequences on patients. The cases chosen represent frequent challenges for general cardiologists, internists, electrophysiologists and imaging cardiologists managing these patients. The topics of this session will cover 3 different arrhythmic diseases with genetic causes:
1) Excessive trabeculations on cardiac magnetic resonnance: Is this non-compaction?
2) Is this a Brugada syndrome? Dealing with non-diagnostic ECG patterns.
3) Is this long QT syndrome? Pitfalls in QT measurement and diagnosis
The CHRS education committee planned this workshop. Members of this committee include community and academic cardiologists, electrophysiologists, cardiology residents and allied professionals from diverse practices and experience across Canada. The CHRS education committee is composed of representatives from each of the following regions: British Colombia, Prairies, Ontario, Quebec, Atlantic Provinces. The CHRS education committee has developed an objective and balanced representation of the topic of "Overdiagnosis in the cardiogenetics clinic" that is completely free of third-party influence and/or support. A meeting was planned to assess the needs of clinical cardiologists, trainees and internists in the field of arrhythmia management. Selected speakers are representative of diversity in gender and generation as well as the perspective from across Canada.
