Insights
This case study details the successful palliative resection of a rare, high-grade neuroendocrine heart tumor. Surgical intervention prolonged survival and improved outcomes for a patient with advanced cardiac obstruction.
Area of Science:
- Cardiology
- Oncology
- Surgical Pathology
Background:
- Primary cardiac neuroendocrine tumors are exceedingly rare.
- High-grade neuroendocrine carcinoma of the heart presents a significant surgical challenge due to potential for rapid growth and obstruction.
Observation:
- A 70-year-old male presented with progressive dyspnea due to a large, solitary, high-grade neuroendocrine carcinoma.
- The tumor extensively involved the right atrium, superior and inferior vena cavae, aortic root, and interatrial septum.
Findings:
- Palliative tumor resection, excluding the aortic root and trigone, was performed, followed by reconstruction of the right atrium and interatrial septum.
- The patient recovered well with only minor local recurrence at 18 months post-surgery.
Implications:
- Palliative resection of large neuroendocrine cardiac tumors can achieve favorable outcomes and extend patient survival.
- This case highlights the feasibility of surgical management for primary high-grade neuroendocrine cardiac tumors, even with extensive involvement.
Abstract:
We report the successful resection of a solitary, apparently primary, high-grade neuroendocrine carcinoma of the heart, in a 70-year-old man who had presented with progressive dyspnea. The tumor occupied the right atrium and almost completely obstructed the superior and inferior venae cavae; it also involved the aortic root and the interatrial septum. To postpone the patient's impending cardiac failure, we resected the gross tumor except in the region of the aortic root and the trigone, which we debulked. We completely reconstructed the right atrium with pericardium and the interatrial septum with a pericardial patch. The patient recovered uneventfully; 18 months postoperatively, he had experienced only local recurrence in the tumor bed. This case shows that the palliative resection of large neuroendocrine tumors of the heart can yield good outcomes and prolong patient survival. To our knowledge, ours is the only report of a high-grade neuroendocrine cardiac tumor of apparently primary origin to have been resected with good palliative results.
