Assessment of Papillary Muscle Function in Patients with Inferior Wall Myocardial Infarction Using Doppler Tissue Imaging

Clinical significance of papillary muscle late enhancement detected via cardiac magnetic resonance imaging in patients with single old myocardial infarction

“…Recently, it was reported that late enhancement (LE) of PMs was detected by contrast-enhanced MRI in patients with several types of heart disease [7][8][9][10][11][12][13]. PM-LE is thought to indicate PM necrosis or fibrosis, and has been confirmed to correspond with contractile dysfunction of PMs [8]. However, many of the reports on PM-LE were single case studies or used small sample sizes.…”
