About the trial
What the trial wants to find out
The objective of this prospective registry study is to comprehensively characterize the prevalence, (semi-) quantitative parameters, and associated clinical outcomes of mitral (MR) and tricuspid regurgitation (TR) in patients diagnosed with transthyretin amyloid cardiomyopathy (ATTR-CM). The study further aims to develop and implement new grading standards for the quantitative assessment of regurgitation severity, tailored to the distinct hemodynamic profile of ATTR-CM. This approach seeks to address the limitations of current regurgitation severity classifications, which do not adequately reflect the unique pathophysiology of a restrictive phenotype as seen in ATTR-CM.
