Chronic Dissection of the Abdominal Aorta. Endovascular Therapy with Novel Stent-Graft in-situ Fenestration

within 7–10 days in about half of survivors probably after edema resolution, as it is one of the probable mechanisms of conduction disturbances. Permanent pacemaker implantation was indicated in about 50% of the patients due to recurrent or permanent complete AVB and mortality rate was 20%. (8) In our case, the patient presented complete AVB with QRS morphology of complete RBBB. Once the sinus rhythm was restored, the conduction abnormality was a complete LBBB because the left branch was the fascicle injured by the blunt cardiac injury, and persists even 6 months after the accident, which turns the case exceptional. Given the lack of specific recommendations on the need for pacemaker, we believe that reporting this type of case will allow the possibility of making recommendations in the future based on the knowledge of the natural history of patients with cardiac injury after a closed chest injury.
