Introduction: Despite the importance that was assessed in this section, we found in our review that so far no study has evaluated the effectiveness of this type of surgery as well as the recurrence of endocarditis after surgery. Therefore, the aim of this study was to evaluate the effectiveness of heart valve surgery in injecting drug users with infectious endocarditis referred to Tabriz University Center (Shahid Madani Hospital) retrospectively and prospectively, in which patients in the period 2015 to 2020 as a group. Studies have been evaluated and reviewed
Material and Methods: This retrospective study was performed in the period from 2015 to 2020 with the participation of patients addicted to narcotics and endocarditis after heart surgery in Shahid Madani Hospital in Tabriz. The results of these patients were reported in this study.
Results: 5 patients (26.3%) had recurrence of endocarditis after surgery and the overall mortality of patients was equal to 9 patients (47.4%). Of these patients, 4 patients (21.1%) died at the time of hospitalization, 8 patients (42.2%) died less than one year after surgery and 1 patient (2.5%) died one year after surgery. The lack of mortality in this plan was equal to 10 cases (52.6%).
Conclusion: Considering the mortality and high probability of recurrence in injecting drug users with endocarditis, it can be concluded that surgery in this group of patients is associated with high risk and should be more careful in selecting patients requiring surgical treatment.
