The learning curve effect on outcomes with frozen elephant trunk technique for extensive thoracic aorta disease

Objective The purpose of this study was to analyze the learning curve effect on hospital mortality, postoperative outcomes, freedom from reintervention in the aorta and long-term survival after frozen elephant trunk (FET) operation. Methods From July 2009 to June 2018, 79 patients underwent surgery with the FET technique. They had type A aortic dissection (acute 7.6%, chronic 33%), type B aortic dissection (acute 1.26%, chronic 34.2%), and...
