Surgical Management of Primary and Metastatic Cardiac Malignancies: A 20-Year Single-Center Experience

Key Result

Surgical resection of malignant cardiac tumors resulted in a median overall survival of 11 months, with complete (R0) resection achieved in 20% of patients and no 30-day mortality.

Key Points

To evaluate the outcomes of surgical management for primary and metastatic malignant cardiac tumors over a 20-year period.
Reviewed surgical cases from a single institution over 20 years
Analyzed patient outcomes related to primary and metastatic cardiac tumors
Evaluated efficacy of surgical resection for symptom relief and survival
Surgical resection performed on both primary and metastatic cardiac tumors
Efficacy of surgical intervention for improving prognosis was found to be limited
Symptom relief achieved but overall survival benefits were not significantly enhanced

Study Design

Type

Observational (n=15)

Multicenter

Structured PICO

Population

Patients with primary and metastatic malignant cardiac tumors

Intervention

Surgical resection

Limitations

Retrospective design is susceptible to selection bias
Small sample size of 15 patients collected over 2 decades limits statistical power
Long study period introduces heterogeneity in diagnostic imaging, surgical techniques, and adjuvant therapies

Abstract

Purpose: Malignant cardiac tumors are rare and have a poor prognosis. Surgical resection is performed for symptom relief and survival benefit, but its efficacy is limited. We reviewed our 20-year single-institution experience with primary and metastatic malignant cardiac tumors.
