Aortopathy Relationship To Imagery and Kinocardiography Features (ARTIK)
Kinocardiography (KCG) is a portable measurement technique developed to estimate cardiac mechanical performance by studying the vibrations produced by myocardial contraction during each heartbeat and transmitted to the body surface.

The goal of this observational study is to learn about kinocardiography in patients with aortic valve disease (AVD) or thoracic aortic aneurysm (TAA). The investigators believe that this technology will enable us to diagnose aortic valve disease and aortic aneurysm.

In patients with AVD of different severities or TAA, the investigators will collect informations from echocardiography and/or cardiac magnetic resonance imaging and KCG recordings. Researchers will also compare subjects without any AVD nor TAA to better understand these effects on KCG.
