Insights
A large invasive cardiac tumor obstructing heart outflow was diagnosed using intracardiac echocardiography (ICE) guided biopsy. This minimally invasive technique proved effective for diagnosing malignant lymphoma in the heart.
Area of Science:
- Cardiology
- Oncology
- Medical Imaging
Background:
- Cardiac tumors are rare and can present with diverse symptoms.
- Accurate diagnosis is crucial for effective treatment planning.
Observation:
- A 63-year-old female presented with chest discomfort and edema, indicative of potential cardiac compromise.
- Transthoracic echocardiography identified a large, invasive tumor obstructing the right atrium and ventricle.
Findings:
- Transvenous intracardiac echocardiography (ICE) guided a biopsy of the cardiac tumor.
- Histopathological analysis confirmed the diagnosis of malignant lymphoma.
Implications:
- ICE-guided biopsy offers a minimally invasive approach for diagnosing cardiac tumors.
- This technique facilitates timely diagnosis and management of life-threatening cardiac conditions.
Abstract:
A 63-year-old woman was admitted to hospital with the chief complaint of new onset chest discomfort and pretibial pitting edema. Transthoracic echocardiography revealed a large invasive tumor on the heart protruding into the right atrium and right ventricle, which obstructed the outflow tract. She underwent transvenous 9Fr, 9-MHz ultra intracardiac echocardiography (ICE) (EP Technologies, Boston Scientific Corporation, San Jose, CA, USA) guided biopsy, and a diagnosis of malignant lymphoma was established from the specimen obtained. ICE-guided cardiac tumor biopsy may be one of the most useful strategies for diagnosis of cardiac tumors.
