Background: Surgical aortic valve replacement (SAVR) is a standard procedure for symptomatic aortic valve disease, however, there was a limited data about this procedure in Thailand especially in terms of long-term outcomes. This study aims to present mid-term results after aortic valve replacement as a single institution.
Methods: A retrospective cohort study was conducted. All 112 consecutive patients who underwent isolated SAVR at Ramathibodi hospital between 2010 – 2015 were enrolled in this study. Patient characteristics, operative procedures, perioperative complications and postoperative outcomes were retrospectively reviewed from medical recording system. The endpoints were overall survival at 30 days, 1 years and 5 years, peri-operative and valve-related complications.
Results: There was 112 patients. Seventy-eight (69%) patients were male. Median age was 66 (IQR 14-87). Median follow-up period was 36 months (IQR 24-60). The most common pre-operative clinical symptoms were congestive heart failure followed by myocardial infarction and angina pectoris. The majority of pathology was degenerative aortic stenosis. Median of Euroscore was 1.5% (0.5-7%). Thirty-day, one-year and three-year survival of isolated SAVR was 98, 96 and 96 % respectively. There were 4.4 % of the patients who required a permanent pacemaker and stroke rate was 1.8%. In subgroup analysis, there was no difference in overall survival between age < 60 and more than 60 years old. (P=0.67)
Conclusion: An isolate aortic valve replacement is a safe procedure with a low post-operative complication and also demonstrate a good long-term outcome.
