Prognostic significance of papillary muscle infarction detected by late gadolinium-enhanced MRI in acute reperfused ST-segment elevation myocardial infarction

چکیده
Background The frequency and prognostic significance of papillary muscle infarction (PapMI) have not been investigated in a large multicenter study of patients with acute reperfused ST-elevation myocardial infarction (STEMI) because papillary muscle necrosis is difficult to visualize premortem. Noninvasive investigation by late gadoliniumenhanced magnetic resonance imaging (LGE-MRI) enables the detection of PapMI with high tissue contrast and spatial resolution. Aim of the study was to assess the exact frequency and clinical characteristics of PapMI using LGE-MRI in patients with STEMI.

Background—The frequency of papillary muscle infarction (PapMI) without rupture has not been fully investigated in vivo. Furthermore, the relationship between papillary muscle dysfunction and mitral regurgitation (MR) has been controversial in patients with ST-segment elevation myocardial infarction. Therefore, the aim of this study was to assess the frequency and clinical characteristics of Pa...
