ARISE clinical study presented at the 31st Annual Meeting of the European Association For Cardio-Thoracic Surgery (EACTS) 2017 in Vienna

Brazilian group reports results of decellularised allografts used for RVOT construction during the ROSS operation

Training workshop for young surgeons held in Barcelona in November 2017

Prof. Dr. Samir Sarikouch presented the current status of the ARISE clinical study during a Focus Session on “Alternative surgical approaches for aortic valve replacement” at the 31st EACTS Meeting in Vienna, Austria on Tuesday 10th of October 2017. He gave an overview about the current inclusion to the clinical trial. So far, 99 patients have been operated within the trial. 14 more operations are already scheduled, which means that the calculated minimal sample size of 120 study participants can be safely achieved in 2018 well ahead of the study schedule.

During the same congress Prof. Francisco da Costa presented the results of “Fresh decellularized versus standard cryopreserved pulmonary allografts for RVOT reconstruction during the Ross operation” operated by his group from Curitiba, Brasil (Abstract No. 0349). He presented data of 190 decellularized allografts used for pulmonary valve replacement with a mean follow-up time of 3.7 ▒ 2.5 years. Freedom from late peak gradients ≥ 40 mmHg was significantly better for the dCell group (95.8%, CI 95%  = 87.9 – 98.6%)  than in the standard cryopreserved group  (88.5%, CI95%  = 82.6- 92.5%) at  10 years (p=0.04). He concluded that “although longer follow-up is still necessary, this study demonstrated that decellularized allografts have superior hemodynamic performance at 10 years when compared to conventional cryopreserved allografts”.

On Friday the 18th of November 28, 2017 the ARISE partners conducted a training workshop for young surgeons focusing on the techniques for the implantation of decellularized homografts for aortic valve replacement. Under the patronage of the former EACTS president Prof. Jose Luis Pomar the workshop was held at the Hospital Clinic Barcelona, Spain.
