Heart Tumor Removal Surgery: Approaches, Risks and Recovery

Written and medically reviewed by Dr. Baraa Alnahhal, MD · Last reviewed: November 2026 · How we review

Quick Answer

Heart tumor removal surgery treats tumors in the heart, most of which are benign, such as myxomas and papillary fibroelastomas. Surgery is advised when a tumor causes symptoms, affects heart function, grows quickly or raises complication risk. Approaches include open-heart, minimally invasive and robotically assisted surgery. Benign tumors are usually removed completely with excellent results.

What the research says

• Robotic myxoma removal meant a faster recovery: in 94 people having a left atrial myxoma removed, robotic surgery had no deaths and led to less drainage, shorter time on a ventilator, a shorter hospital stay and faster return to exercise than sternotomy, though bypass time was longer and cost higher (Liu Y et al., Asian Journal of Surgery, 2024) [2]

• Small-port robotic tumor removal was safe: in 18 robotic heart tumor removals through five 8-mm ports, there were no deaths during surgery or reoperations for bleeding, and the median hospital stay was 4.5 days (Rosen JL et al., Journal of Cardiac Surgery, 2022) [3]

Key takeaways

• Most heart tumors are benign, mainly myxomas and papillary fibroelastomas.

• Surgery removes tumors that cause symptoms or raise stroke risk.

• Options are open, minimally invasive and robotic surgery.

• Robotic surgery offers a shorter stay and faster recovery.

• Benign tumors are usually removed completely.

What is heart tumor removal surgery?

Cardiac tumors that start in the heart are rare, and most are benign. Cancerous ones, such as cardiac angiosarcoma, are extremely rare and often aren't treated with surgery. The surgery may include valve repair or replacement. Sources: [1]

Why it's done

Myxomas and papillary fibroelastomas are the most common.

• Benign tumors that cause symptoms.

• Tumors that affect heart or valve function.

• Tumors that raise the risk of blood clots or stroke.

• Tumors that grow quickly.

• Cancerous tumors, to ease symptoms. Sources: [1]

Surgical approaches

Robotic surgery offers the fastest recovery.

Approach	How it's done	Notes
Open-heart	Incision through the breastbone	Used for complex tumors
Minimally invasive	Small incisions	Lower complication risk
Robotic	Several tiny cuts between the ribs	Shortest stay and fastest recovery

Sources: [1, 2, 3]

How to prepare

• Tests may include CT, an echocardiogram, MRI and a coronary angiogram.

• Follow instructions about medicines and fasting.

• Quit smoking and tobacco in the weeks before. Sources: [1]

What happens during surgery

Valve repair or replacement may be done at the same time.

1. You get general anesthesia.

2. A heart-lung machine takes over so the heart can be stilled.

3. The surgeon makes one or more chest incisions.

4. The tumor is removed, and any repair is done.

5. The incisions are closed. Sources: [1]

Risks

• Allergic reaction to anesthesia.

• Abnormal heart rhythms.

• Bleeding.

• Temporary confusion.

• Damage to blood vessels or organs.

• Infection.

• Stroke. Sources: [1]

Minimally invasive and robotic methods lower complication risk. Sources: [1, 2]

Recovery

• You'll spend one or more days in the ICU.

• A robotic surgery hospital stay is typically three to four days.

• Robotic surgery has less pain and bleeding and a faster recovery.

• Return to activities and work when you're ready. Sources: [1, 2, 3]

Outlook

Surgery eases symptoms, lowers complication risk and improves quality of life. Benign myxomas and papillary fibroelastomas are usually removed completely with very successful results. Complex or cancerous tumors may be only partly removable. Sources: [1, 2]

When to call your provider

• Chest pain that doesn't improve.

• Fever.

• Nausea and vomiting.

• Shortness of breath.

• Redness or oozing at the incision.

• Slurred speech or other stroke signs. Sources: [1]

Conclusion

Heart tumor removal surgery can cure most benign heart tumors and prevent strokes and valve damage. Robotic options let many people recover faster with smaller scars.
