“…Conventional echocardiography can detect only fibrosis and calcification of papillary muscles. 22 Strain analysis of papillary muscle requires special echocardiography equipment and good echocardiographic images. Conventional nuclear medicine equipment lacks sufficient spatial resolution to visualize the papillary muscle reliably except in patients with hypertrophic cardiomyopathy.…”

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 PapMI without rupture using late gadolinium-enhanced magnetic resonance imaging (MRI) in patients with ST-segment elevation myocardial infarction. Methods and Results-One hundred eighteen ST-segment elevation myocardial infarction patients with primary percutaneous coronary intervention underwent cardiac MRI twice 9Ϯ4 days and 8Ϯ1 months (nϭ104) after myocardial infarction. MR was categorized by echocardiography. Of these patients, 40% were found to have late gadolinium enhancement of papillary muscle, in which the posterior papillary muscle was involved more frequently than the anterior papillary muscle (77% versus 26%; PϽ0.001). PapMI was encountered more frequently in patients with left circumflex and right coronary artery lesions compared with left anterior descending artery lesion (78%, 48%, and 13%; PϽ0.001).By multiple logistic regression analysis, only coaptation height was identified as an independent predictor of the presence of MR. The second cardiac magnetic resonance imaging showed that the infarct size had a positive correlation with left ventricular end-diastolic volume (rϭ0.41, PϽ0.001) and that PapMI was not associated with left ventricular remodeling (Pϭ0.31). Deterioration of MR was not observed in patients with PapMI. Conclusions-PapMI is more frequent than previously thought yet appears to have significant clinical latency. The size of the myocardial infarction, but not the presence of PapMI, seems to affect left ventricular remodeling, and PapMI is not obligatorily associated with MR.

“…This shortening of the papillary muscles results in an abnormal pulling on the chordae tendineae leading to moderate–to‐severe valve regurgitation and complete rupture of the papillary muscle in some cases . Therefore, when valve regurgitation or coronary artery occlusions are discovered, papillary muscle injury and calcification should be considered as a co‐occurrence, having some association with the concomitant pathology . It has been shown that echocardiography can be advantageous in evaluating patients who present with these conditions.…”

Intrinsic and Extrinsic Cardiac Pseudotumors: Echocardiographic Evaluation and Review of the Literature

et al. 2015

Echocardiography is the most common imaging modality for the assessment of cardiovascular tumors, followed by more advanced imaging modalities, such as cardiac computed tomography or cardiac magnetic resonance imaging. Non-neoplastic lesions that may simulate a true neoplasm on imaging are termed "cardiac pseudotumors." As echocardiography is the initial imaging modality where pseudotumors are identified, it is imperative to have a fundamental understanding of pseudotumors evaluation using echocardiography. There is paucity of the literature describing the different kinds of pseudotumors. This review is an attempt to describe common cardiac pseudotumors and to classify them based on their origin. The tumors arising from cardiac structures, such as epicardium, endocardium, or myocardium, were termed as "intrinsic" while the pseudotumors with no cardiac origin were termed as "extrinsic." The more common pseudotumors are described in detail with pertinent echocardiographic features and examples.
