Key result
Mechanical AVR carries ~9% in-hospital mortality with ~59% five-year survival in octogenarians.
Why the study?
Long-term outcomes of mechanical aortic valve replacement in octogenarian patients were not well characterized.
Observational (n=23)
No
Mechanical aortic valve replacement in octogenarians is associated with acceptable hospital mortality and midterm survival, suggesting it remains a viable option for selected elderly patients.
Supports evaluation of mechanical AVR in selected octogenarians; leaves open need for larger comparative studies before broader adoption.
Aim: This study analyzes the long-term outcomes of mechanical aortic valve replacement in octogenarian patients. Material and Method: A retrospective review was performed on 23 octogenarian patients who underwent mechanical aortic valve replacement. Hospital mortality, postoperative intensive care unit stay, hospital stay and long-term results was examined. Estimates of the cumulative event mortality rate were calculated by the Kaplan-Meier method. Results: The mean age of all patients was 82.9±2.3 years and most were men (65.22%). The median ejection fraction was 45%. 73.91% of patients were in New York Heart Association class III-IV. Thirteen patients (56.52%) in this study underwent combined procedure, the remaining 10 (43.48%) patients underwent isolated aortic valve replacement. The most common valve size was 23 mm. The mean intensive care unit stay was 1.76±1.14 days. The mean hospital stay was 9.33±5.06 days. No complications were observed in 56.52% patients during their hospital stay. The overall hospital mortality was 8.7%. Follow-up was completed for all 23 patients. Median follow-up time was 33 months (1-108 months). Actuarial survival among discharged from hospital was 59% at 5 years. Discussion: Mechanical aortic valve replacement is a safe procedure in octogenarian patients and can be performed safely even in combined procedure.

İrfan Taşoğlu (2014) conducted an observational in Aortic valve disease (n=23). Mechanical aortic valve replacement was evaluated on Hospital mortality. Mechanical aortic valve replacement in octogenarians demonstrated an overall hospital mortality of 8.7% and a 5-year actuarial survival of 59% among discharged patients.
