Surgery for primary cardiac tumors. Clinical experience and surgical results in 60 patients.
BACKGROUND
We reviewed our clinical experience with primary cardiac tumors, attempting to clarify the surgical management of these rare entities.


METHODS
Between October 1978 and November 1999, we experienced 60 surgical cases of primary cardiac tumors. There were 23 male and 37 female patients (age range, 7 months to 84 years). Tumors included the following 3 groups: myxomas (n=49), nonmyxoma benign tumors (n=3), and malignant tumors (n=8). We reviewed the presenting symptoms, diagnostic data, anatomical findings, and surgical techniques, and evaluated the surgical RESULTS. Late follow-up was 95% complete (mean follow-up, 7.7+/-7.1 years).


RESULTS
Tumors produced obstructive, embolic, and/or constitutional symptoms in most cases. Generally, echocardiography alone gave sufficient information for operation. Full-thickness excision was performed in 42 patients with myxoma. Complete excision was achieved in all of the nonmyxoma benign tumors and in none of the malignancies. Early mortalities in the 3 groups were 8.2% (4/49), 0% (0/3), and 12.5% (1/8), respectively. Late mortalities were 9.5% (4/42), 0% (0/3), and 100% (7/7), respectively. One patient with myxoma had recurrence, the cause of which was likely to be inadequate resection. The late deaths in patients with malignancies were due to metastasis or local recurrence.


CONCLUSIONS
Benign tumors are generally curable if surgically excised. Preoperative refractory cardiac dysfunction or embolism should be avoided by the accurate evaluation on echocardiography. The prognosis of malignant tumors is poor if they are only debulked. However, aggressive surgery that can palliate obstruction and allow time for adjuvant therapy should be carried out.
