Insights
Surgical resection of cardiac myxoma offers excellent long-term survival rates with a low risk of recurrence. This 30-year study confirms the safety and efficacy of myxoma removal surgery.
Area of Science:
- Cardiovascular Surgery
- Cardiac Oncology
- Thoracic Surgery
Background:
- Primary cardiac tumors are rare, with myxoma being the most frequent type.
- This study reviews 30-year clinical outcomes of surgical myxoma resection.
Purpose of the Study:
- To summarize long-term clinical outcomes and recurrence rates after surgical myxoma resection.
- To evaluate the impact of surgical approach on patient outcomes.
Main Methods:
- Retrospective analysis of 93 patients undergoing surgical myxoma resection between 1986 and 2015.
- Data collected on patient demographics, tumor characteristics, surgical techniques, and follow-up outcomes.
- Surgical approaches included biatrial approach, atrial septotomy, and left atriotomy.
Main Results:
- Mean follow-up was 9.9 years; in-hospital mortality was 3.2%.
- Common postoperative complication was atrial fibrillation (4.3%).
- Excellent 5-, 10-, and 30-year survival rates of 92.9%, 87.2%, and 75.5% respectively; recurrence rate was 2.1%.
Conclusions:
- Long-term survival following surgical myxoma resection is excellent.
- Recurrence of cardiac myxoma after resection is rare.
- The surgical method employed did not significantly impact patient outcomes.
Background:
Primary cardiac tumors are rare and myxoma constitutes the majority. The present study summarizes our 30-year clinical outcomes of surgical myxoma resection.
Methods:
Between January 1986 and December 2015, 93 patients (30 men, 63 women; mean age, 54.7 ± 16.6 years) underwent surgical myxoma resection. The most common origin site was the left atrium. Surgery was performed via a biatrial approach in 74.2%, atrial septotomy through right atriotomy in 17.2%, and left atriotomy only in 8.6%. Mean myxoma size based on longest length was 4.73 ± 1.92 cm (range, 1.2-11.0 cm).
Results:
The mean follow-up duration was 9.9 ± 7.8 years (range, 0-29 years). In-hospital mortality was 3.2%. The most common postoperative complication was atrial fibrillation (4.3%). The 5-, 10-, and 30-year survival rates were 92.9%, 87.2%, and 75.5%, respectively. Recurrence occurred in two patients (2.1%), which were detected at 20 and 79 months after the first surgery, respectively.
Conclusions:
Long-term survival after myxoma resection was excellent and recurrence was rare. Based on our experience, surgical method did not affect the outcome.
