Summary
Complete surgical resection and cardiomyoplasty offer a promising alternative to heart transplantation for large ventricular tumors. This approach led to improved patient function and no recurrence in long-term follow-up.
Area of Science:
- Cardiovascular Surgery
- Surgical Oncology
- Regenerative Medicine
Background:
- Complete surgical resection of ventricular tumors is challenging.
- Cardiac transplantation is an option but has limitations.
- Ventricular reconstruction following tumor resection is desirable for improved outcomes.
Purpose of the Study:
- To evaluate the efficacy of extensive surgical resection and dynamic cardiomyoplasty for ventricular tumors.
- To assess the feasibility of ventricular reconstruction as an alternative to heart transplantation.
- To determine the long-term prognosis for patients undergoing this procedure.
Main Methods:
- Seven patients with ventricular tumors underwent complete resection.
- Surgical steps included tumor resection, coronary artery bypass grafting (if needed), valvular reconstruction/replacement, and ventricular reconstruction using a pericardial patch and latissimus dorsi muscle flap.
- The latissimus dorsi muscle flap was electrostimulated to create a neomyocardium.
Main Results:
- All patients survived the initial surgery, with two late deaths.
- Early complications included arrhythmias, heart block, respiratory insufficiency, and heart failure.
- Postoperative follow-up showed significant improvement in functional status, from NYHA class 2.8 to 1.2.
Conclusions:
- Dynamic cardiomyoplasty following extensive tumor resection is a viable alternative to heart transplantation.
- The procedure demonstrated excellent long-term results without tumor recurrence or significant ventricular dysfunction.
- This approach offers a better prognosis for patients with malignant ventricular tumors.
