Endocardial stem cell implantation is an innovative medical procedure aimed at restoring cardiac tissue in patients with severe heart disease. During this procedure, stem cells are delivered directly into the endocardium (the inner layer of the heart wall) to stimulate regeneration of damaged myocardium, improve myocardial perfusion, and enhance overall cardiac function.
Stem cells, due to their capacity for differentiation and self-renewal, are introduced into damaged areas of the heart. They contribute to:
- Tissue regeneration. Replacement of damaged or scarred tissue with newly formed cells.
- Angiogenesis. Formation of new blood vessels, improving blood supply to the heart.
- Reduction of inflammation. Attenuation of inflammatory processes typical of chronic heart disease.
- Improvement of cardiac function. Enhancement of myocardial contractility.
When is stem cell implantation used?
Main indications for the procedure include:
- Chronic heart failure. Progressive weakening of the myocardium due to ischemia or prior myocardial infarction.
- Coronary artery disease (CAD). Improvement of perfusion in affected myocardial regions.
- Cardiomyopathy. Restoration of cardiac function in the presence of structural myocardial changes.
- Myocardial scarring. Treatment of post-infarction sequelae to improve myocardial contractility.
How is endocardial stem cell implantation performed?
- Preparation for the procedure. The patient undergoes a comprehensive evaluation, including ECG, echocardiography, angiography, and blood tests. Stem cells are harvested from the patient’s own bone marrow or adipose tissue, then processed and prepared for administration.
- Procedure. Implantation is performed via cardiac catheterization under local anesthesia. Using a specialized catheter, stem cells are delivered directly into the affected areas of the myocardium (endocardially). Administration is guided by echocardiographic or angiographic imaging.
- The procedure lasts approximately 1–2 hours. After completion, the patient remains under specialist observation.
Advantages of the method
- Minimally invasive. No need for open-heart surgery.
- Physiological restoration. Use of autologous cells minimizes the risk of immune rejection.
- Suitable for patients with contraindications to surgery. An option when other treatments are ineffective or not feasible.
- Improved quality of life. Reduction of symptoms such as dyspnea, fatigue, and chest pain.
Long-term outcomes
- Improved cardiac function. Increase in left ventricular ejection fraction and myocardial contractility.
- Reduced risk of complications. Lower likelihood of recurrent myocardial infarction and progression of heart failure.
- Improved survival. The method may prolong survival in patients with severe forms of heart disease.
Endocardial stem cell implantation is performed in specialized medical centers in Belarus using advanced technologies. Highly qualified specialists ensure precise execution of the procedure and safe cell delivery. This innovative approach can improve quality of life in patients with serious cardiovascular diseases.
