A pregnant woman with a right atrial tumor underwent successful surgical removal after delivery. Pathology confirmed a cavernous hemangioma, highlighting the need for tumor excision to prevent arrhythmias and malignant transformation.
Area of Science:
- Cardiology
- Obstetrics
- Surgical Oncology
Background:
- Pregnancy can present unique challenges in diagnosing and managing cardiac tumors.
- Right atrial tumors, though rare, require careful consideration due to potential complications.
Purpose of the Study:
- To report a case of a large right atrial tumor diagnosed during pregnancy.
- To discuss the management and surgical outcomes of cardiac tumors in pregnant patients.
- To emphasize the importance of tumor removal to prevent adverse cardiac events.
Main Methods:
- Case presentation of a 42-year-old pregnant woman diagnosed with a right atrial tumor.
- Surgical tumor resection performed postpartum.
- Histopathological analysis of the resected tumor.
Main Results:
- A large right atrial tumor was diagnosed in the third trimester of pregnancy.
- The patient underwent successful surgical removal of the tumor three weeks after a full-term delivery.
- Postoperative recovery was uneventful.
- Pathology confirmed the tumor as a cavernous hemangioma.
Conclusions:
- Cavernous hemangiomas of the heart require surgical intervention.
- Timely removal of cardiac neoplasms is crucial to prevent potentially life-threatening complications such as severe arrhythmias.
- Surgical management of cardiac tumors can be safely performed postpartum.
