BACKGROUND: Primary cardiac tumors are rare but have favorable surgical prognosis. Previous studies have been small series studies with limited surgical approaches. To date, few studies have examined the clinical features associated with different surgical procedures.
MATERIAL AND METHODS: In a search of the cardiovascular surgery database of our institution, we retrospectively identified 225 patients who had cardiac tumor resection from January 1993 to May 2016. The patients’ clinical characteristics and operation information were reviewed, and the operation parameters, postoperative complications, and short-term prognosis among robotic, mini-thoracotomy, and conventional procedures in our center were compared.
RESULTS: A total of 228 operations were performed, including 156 traditional open surgeries (68.4%), 60 robotically assisted neoplasm resections (26.3%), and 12 mini-thoracotomy procedures (5.3%). Among 232 lesions, myxoma (94.8%) was the most common neoplasm, and the remainders were fibroma (1.3%) and lipoma (0.9%). Operative complications occurred in 36 patients (15.8%). Arrhythmia (8.8%) was the first common complication, and delayed mechanical ventilation (4.8%) ranked second. The overall risk of recurrence of myxoma was 2.7%. The cardiopulmonary bypass (CPB) time in the mini-thoracotomy group was longer than in the robotic group (p=0.034) and the conventional group (p=0.002). There were no significant differences in cross clamp time (p=0.266) or complications (p=0.835) among the three groups. The in-hospital survival rate was 100% in all patients. There were no significant differences in main adverse events among the three groups at six-month follow-up (p=0.285).
CONCLUSIONS: Prognosis for cardiac neoplasm surgical resection is favorable for primary cardiac tumors. The minimally invasive surgery of cardiac tumor resection can be an alternative to conventional operations in selected patients.
