h.TRAIPTA

The transatrial intrapericardial tricuspid annuloplasty (TRAIPTA) system is an external indirect annuloplasty device. It consists of an adjustable nitinol guide that is advanced through the inferior vena cava to the atrium and penetrating the pericardium through a puncture in the right appendage. Once within the pericardial space, it is positioned in the atrioventricular sulcus, adjusting its size and thus reducing the diameter of the tricuspid ring and improving coaptation of the leaflets. The first experience was with a porcine model, in which a decrease in TR was achieved, with improvement of coaptation and reduction of the diameter of the ring, without serious complications [52]. The puncture zone was sealed with an atrial septal occluder (Amplatzer, St. Jude Medical, St. Paul, Minnesota or Lepu Medical, Beijing, China) in all cases. Although no results in humans are yet available, a new version of the device will be evaluated in a feasibility trial in the coming years.
