False Tendon in Cardiovascular Diseases: Friend Foe or Bystander?

摘要

In this issue, Presti et al.1) reports the protective role of left ventricular (LV) false tendon against LV remodeling and functional mitral regurgitation (MR) after acute myocardial infarction. Unfortunately, the authors did not obtain positive results that false tendon has a protective effect against adverse LV remodeling and ischemic MR. There are many limitations in this study, such as a small study group, a retrospective design, participants with a mild degree of LV systolic dysfunction on baseline echocardiography, low echocardiographic sensitivity to detect the presence of false tendons, and weak consideration of the differences in the anatomical characteristics of false tendon. Therefore, it is difficult to generalize the results of this study. If a new study is carried out with a modified design to address these shortcomings, however, other interesting results might be obtained.
