Key result
TEE provides superior visualization over TTE for diagnosing papillary muscle rupture complicating acute MI.
Why the study?
Papillary muscle rupture is a life-threatening complication of acute myocardial infarction requiring swift diagnosis and prompt surgical intervention, where transesophageal echocardiography plays an important role.
Does transesophageal echocardiography improve the identification of papillary muscle rupture complicating acute myocardial infarction compared to transthoracic echocardiography?

Does transesophageal echocardiography improve the identification of papillary muscle rupture complicating acute myocardial infarction compared to transthoracic echocardiography?
Transesophageal echocardiography is a crucial imaging modality for the accurate diagnosis and anatomic characterization of papillary muscle rupture complicating acute myocardial infarction, especially when transthoracic echocardiography is inconclusive.
May warrant TEE when TTE inconclusive for suspected post-MI papillary muscle rupture; leaves open need for prospective validation.
Papillary muscle rupture (PMR) is a rare but potentially life-threatening complication of acute myocardial infarction (AMI). Optimal outcomes require swift diagnosis and prompt surgical intervention, and transesophageal echocardiography (TEE) plays an important role in the process. We present a missed diagnosis case of PMR in the initial procedure and review the literature, focusing on the features of diagnosis, which may be beneficial in clinical management.

Peng et al. (2022) conducted a case report in Papillary muscle rupture complicating acute myocardial infarction (n=25). Transesophageal echocardiography (TEE) vs. Transthoracic echocardiography (TTE) was evaluated. Transesophageal echocardiography provides superior visualization of the submitral apparatus and is essential for accurately diagnosing papillary muscle rupture complicating acute myocardial infarction.
