Original Title:
Surveillance par imagerie d’une dilatation dégénérative de l’aorte ascendante chez l’adulte
Authors' objectives:
In collaboration with the Ministère de la Santé et des Services sociaux (MSSS), the
Réseau québécois de cardiologie tertiaire asked the Institut national d’excellence en
santé et en services sociaux (INESSS) to develop clinical guidelines regarding the use of
medical imaging tests, as well as reasonable and safe imaging frequencies, when
monitoring the progression of degenerative dilatation of the ascending thoracic aorta in
adults.
Authors' results and conclusions:
RESULTS: Briefly, an initial follow-up imaging test is indicated 12 months after the discovery or
diagnosis of degenerative dilatation of the ascending aorta. Subsequently, additional
follow-up tests may be indicated, with a surveillance schedule tailored to patient
characteristics and based on the results of the initial follow-up—namely, aortic diameter,
rate of progression of dilatation over time, and the presence of risk factors for
complications.
Authors' recommendations:
The recommendations resulting from this work specifically target degenerative dilatation
of the ascending thoracic aorta, defined as a diameter measuring between 40 mm and
44 mm, or a diameter indexed to body surface area of greater than 22 mm/m². In
contrast, an aneurysm is defined as a significant enlargement of the ascending thoracic
aorta, with a diameter equal to or greater than 45 mm.
Authors' methods:
A rapid review of documents presenting recommendations or clinical indications
regarding the subject under evaluation was conducted in accordance with INESSS
methodological standards.
A consultative committee of primary care clinicians, medical imaging specialists,
cardiologists, and cardiac/vascular surgeons was formed to assess the available
evidence and to provide contextual and experiential information.
