Diagnostic Pitfalls in Papillary Muscle Rupture-Associated Acute Mitral Regurgitation after Acute Myocardial Infarction

Figure 3

Transthoracic and transesophageal echocardiogram on day 5. (a) A fluttering mass in the left ventricle (LV), suggestive of papillary muscle rupture (white arrow) on apical two-chamber view. (b) Systolic-phase view with color doppler showing systolic jet towards the probe, indicative of mitral regurgitation. (c, d) Systolic- and diastolic-phase images of the completely ruptured posterior papillary muscle moving between the LV and left atrium (white arrow).
