Cardioplasty according to Marwedel for the correction of congenital heart disease is not a new surgical technique, but at the same time it is widely practiced in leading specialized cardiac surgery centers in different countries. Approaches to performing this operation, the scope and indications for it remain the subject of discussion among cardiac surgeons over the years, based on the experience and modernity of research.
The first mention of cardioplasty in infancy during surgery for a ventricular septal defect dates back to the mid-20th century; it was performed simultaneously with oval correction (Fallot’s triad), and the patch area reached up to 60% of the LV area (and sometimes even more) – like a conical “ball”. The operation is a LV plastic surgery. It arose as a consequence of the colossal scientific breakthrough of Academician B.V. Petrovsky, representing the specialized Republican Children's Republican Clinical Cardiology Center. In 1993, the first work in Russia using this method was published with a detailed description of the examination complex and surgical treatment plan for a child with Down syndrome in combination with an atrial septal aneurysm. It was a wonderful experience, although at that time I did not know the volume of the upcoming operation, which amounted to about 30% of the total area of the LV with subsequent complications that were critical for this patient. Prior to this, a group of foreign scientists led by N. Semperger used more modest patch sizes while maintaining the radial orientation of the sinus node, but they recommended limiting the LV area to at least 50%. Surgical interventions in children over one year of age were performed in the Department of Cardiothoracic Surgery of the Stavropol State Medical University - Professor S.
