Cardiac Tumor Within the Left Ventricle: Thrombus or Something Else?

Area of Science:

• Cardiovascular Medicine
• Cardiac Pathology
• Diagnostic Imaging

Background:

• Papillary fibroelastoma is a rare, benign primary cardiac tumor.
• It most commonly originates from the endocardium of heart valves.
• Embolic complications are a primary concern, often necessitating surgical resection.

Purpose of the Study:

• To present a clinical case of a papillary fibroelastoma located at the left ventricular apex.
• To illustrate the diagnostic challenges posed by this tumor, particularly when visualization is limited on advanced imaging.
• To emphasize the utility of a multimodality imaging approach in managing such cases.

Main Methods:

• Transthoracic echocardiography for initial detection of the cardiac mass.
• Multimodality imaging, including advanced techniques, for detailed characterization.
• Multidisciplinary team approach for diagnosis and treatment planning.

Main Results:

• A 1.3 x 1.1 cm mobile, sessile mass was identified at the left ventricular apex.
• The tumor presented diagnostic challenges due to suboptimal visualization on higher-resolution imaging.
• Successful management involved a coordinated team and comprehensive imaging strategy.

Conclusions:

• Left ventricular papillary fibroelastomas, though rare, require careful diagnostic consideration.
• Multimodality imaging is crucial for accurate characterization and management planning.
• A multidisciplinary approach ensures optimal patient care for challenging cardiac tumor presentations.
