Introduction:

The mid and long term survival rate is a necessary parameter to evaluate the outcomes of heart valve surgery.

Objectives:

To determine the five-year survival of patients who underwent aortic and/or mitral valve surgery, and the variables that could independently predict a lower survival in the follow-up.

Method:

A cohort study was conducted for evaluating 139 patients who underwent a heart valve surgery, in the period 2010-2012, at the Instituto de Cardiología y Cirugía Cardiovascular of Havana, Cuba, all of which survived the postoperative period, and were followed up to five years after the surgery. A Kaplan-Meier curve was performed to determine the survival after surgery. Also, a multivariate Cox regression was carried out to determine the variables that were independently associated with a lower survival rate. The statistical significance level used was p<0.05.

Results:

The sample was homogeneous according to clinical and demographic variables. The overall survival rate was 93% at the end of the study, with a mean follow up of 5.8 years. The older age (HR=1.15; p=0.001) and the history of perioperative low cardiac output syndrome (HR= 3.54; p=0.037) were the variables independently associated to lower survival in the follow-up.

Conclusions:

The patients’ survival when concluded the follow-up was high. The older age and the perioperative low cardiac output syndrome were the variables independently associated to lower survival.
