The International Thoracic Organ Transplant (TTX) Registry was created to provide on-going, current data regarding patient, donor, and transplant characteristics as well as post-transplant outcomes.  Our Registry is the only one of its kind.  All institutions and countries performing heart, heart-lung, and/or lung transplantation are invited to submit data to the TTX Registry.
