Author’s Reply: Further expanding possibilities of successful stem cell transplantation in coronary artery disease/An alternative approach of stem cell delivery to myocardium: combined usage of antegrade coronary arterial infusion and retrograde venous obstruction

We thank the authors for the interest and supportive letter on our case report “An alternative approach of stem cell delivery to myocardium: combined usage of antegrade coronary arterial infusion and retrograde venous obstruction” (1). Cardiac stem cell therapy is a novel, promising method for the treatment of cardiovascular disease. Many previous studies demonstrated the beneficial effects of stem cells on left ventricular function after acute or chronic ischemic injury (2-4).
