Key result
Secondary structural cardiac damage in mitral regurgitation leads to excess mortality, prompting staging classification to assess prognosis in transcatheter edge-to-edge repair.
Registry study evaluates cardiac damage staging in primary mitral regurgitation, highlighting the prognostic impact of extra-valvular damage after transcatheter repair.
Mitral regurgitation (MR) is often associated with significant secondary structural cardiac damage which leads to excess mortality. There are limited data on the staging of MR based on the degree of extra-valvular cardiac damage and impact on prognosis.
