Heart Transplantation
Conditions
Brief summary
The goal of this prospective randomized single blind multicenter phase II study is to compare organ perfusion with Custodiol-N and Custodiol in heart transplantation in children of all ages (birth to \<18 years) being listed on the waiting list for heart transplantation. The main question it aims to answer is: to compare the safety of Custodiol-N in heart transplantation in children in comparison to its precursor product Custodiol. Participants will receive either a heart to be transplanted, either perfused with Custodiol-N or Custodiol to Researchers will compare the two solutions to see if the new solution Custodiol-N is safe in heart transplantation in children.
Detailed description
Orthotopic Heart transplantation (or cardiac transplantation) is a procedure performed in patients with end stage heart failure when other treatments have failed. The surgical procedures for orthotopic heart transplantation are essentially the same in adult and paediatric patients . Due to anatomical variants in congenital heart disease the procurement procedure may be modified with regard to the extent of the Vena cava superior and the great vessels. In implantation most frequently the bicaval technique is used but the biatrial technique which is leaving the back wall of both atria in situ may also be employed. A main difference between adult and paediatric heart transplantation (HTx) are the indications for transplantation: In adults the majority of patients undergo HTx as treatment of end stage heart failure due to cardiomyopathy or severe coronary artery disease when other treatments have failed. Infants younger than one year of age congenital heart disease (CHD) is the most common diagnosis representing more than every second case followed by dilated cardiomyopathy (DCM) in more than one third of cases. In older patients DCM is the most frequent underlying diagnosis. CHD may include patients who have undergone corrective surgery and in whom myocardial dysfunction develops later .
