Background:
Little is known about the echocardiographic characteristics of primary malignant pericardial mesothelioma (PPM) due to its rarity. The aim of this study was to explore the sex-specific echocardiographic patterns of PPM and risk factors for in-hospital mortality.
Methods:
A retrospective information retrieval was conducted for cases of PPM reported from China during 1981 and 2015. The diagnosis was made by histopathological examinations and only cases with echocardiographic descriptions were included. Data on the clinical and echocardiographic findings were collected. Difference in clinical, sex-specific echocardiographic characteristics and findings across different time periods were assessed. Logistic regression analysis was performed to explore echocardiographic risk factors for in-hospital mortality.
Results:
A total of 64 patients with PPM were included, with a mean age of 39.2 ± 15.6 years and minor male dominance (40, 62.5%). The most common echocardiographic presentations were pericardial effusion (55, 85.9%), pericardial masses (36.4%) and thickening (17.3%), respectively. The positive rate of pericardiocentesis was only 20.9%. Six patients (15.4%) died among 39 cases reporting in-hospital outcome. Logistics analysis identified no clinical or echocardiographic parameters associated with in-hospital mortality (all P > 0.05).
Conclusions:
The echocardiographic signs of PPM are basically nonspecific with massive pericardial effusion as the most common sign, although no echocardiographic gender differences or association with in-hospital mortality could be identified.
Insights
Primary malignant pericardial mesothelioma (PPM) rarely shows specific echocardiographic signs, with large pericardial effusion being most common. No echocardiographic factors were linked to in-hospital mortality in this study.
Area of Science:
- Cardiology
- Oncology
- Medical Imaging
Background:
- Primary malignant pericardial mesothelioma (PPM) is rare, limiting understanding of its echocardiographic features.
- Echocardiography is crucial for diagnosing and managing pericardial diseases.
Purpose of the Study:
- To investigate sex-specific echocardiographic patterns of PPM.
- To identify echocardiographic risk factors for in-hospital mortality in PPM patients.
Main Methods:
- Retrospective analysis of 64 histopathologically confirmed PPM cases from China (1981-2015).
- Inclusion criteria: availability of echocardiographic descriptions.
- Logistic regression used to assess mortality risk factors.
Main Results:
- Most common findings: pericardial effusion (85.9%), masses (36.4%), thickening (17.3%).
- Pericardiocentesis positive rate was low (20.9%).
- No significant associations found between clinical/echocardiographic parameters and in-hospital mortality.
Conclusions:
- Echocardiographic signs of PPM are generally nonspecific.
- Massive pericardial effusion is the most frequent echocardiographic manifestation.
- No sex-specific echocardiographic differences or mortality predictors were identified.
