Abstract

Background: Mean age of patients with valves diseases is significantly increasing, and, in the near future, cardiac surgeons will have to deal with a considerable number of patients aged more than 80 years. The remarkable results gained by the minimally invasive approach have encouraged its application in more complex and fragile patients, such as older people. This study aimed to identify the rate of early mortality and major complications, and independent predictors for mid-term mortality in octogenarians undergoing minimally invasive valve surgery.

Methods: Octogenarian patients undergoing right mini-thoracotomy mitral and/or tricuspid valve surgery between 2006 and 2020 were included. Primary endpoint was to identify independent predictors for mid-term mortality, and secondary endpoints were operative morality, stroke, independent predictors for early composite outcome, and quality of life at follow-up.

Results: Analysis was performed on 130 patients. Stroke occurred in one patient (0.8%), while operative mortality was 6% (eight patients). One-year and five-year survival were 86% and 64%, respectively. Logistic regression identified age and creatinine level as independent predictors of mid-term mortality, survival analysis showed that age ≥ 84 years and creatinine level ≥ 1.22 mg/dL were the cut-off points for worst prognosis. Female gender and hypertension were found to be independent predictors of early composite outcome.

Conclusions: Results of the present study show that age alone should not be considered a contraindication for minimally invasive valve surgery. Identifying patients who are most likely to have survival and functional benefits after surgery is decisive to achieve optimal health outcomes and prevent futile procedures.
