ABSTRACT

Objective:

To investigate the difference between the short-term and long-term survival rates of patients undergoing tricuspid valve replacement with biological and mechanical valves.

Methods:

273 patients who received tricuspid valve replacement were selected from our Hospital from November 1993 to August 2018. The mean follow-up time was(8.2±5.6) years. The total follow-up rate was 95%. Kaplan-Meier method was used to make survival curves of the two groups and log rank test was used to compare the differences between the two groups. In addition, this study made the comparison of preoperative, intraoperative and postoperative information and long-term survival rate between these two groups.

Results:

There was no significant difference in demographic characteristics and baseline between mechanical valve group and biological valve group. 16 patients died in the mechanical valve group and 22 in the biological valve group. In the mechanical valve group, 14 cases died of postoperative low cardiac output syndrome and 2 cases died of gastrointestinal hemorrhage. 22 patients were died of low cardiac output syndrome. The auxiliary time in the mechanical valve group was longer than that in the biological valve group[(151.76±70.30)min vs.(131.62±60.25)min, P=0.013)]. There was no significant difference in long-term survival rate between the two groups in Kaplan- Meier survival curve( P=0.234).

Conclusion:

There is no difference in short-term and long-term survival rate between mechanical valve and biological valve in tricuspid valve replacement.
