Objective:
Isolated tricuspid valve (TV) surgery remains underused despite guideline recommendations. This underuse may be related to perceived high risk in comorbid patients but also to high reported needs for postoperative permanent pacemaker implantation (PPI). It is conceivable that PPI can be prevented by operating on the beating heart (BH). We conducted a systematic review and meta-analysis assessing the influence of BH versus arrested heart (AH) technique on short-term and long-term outcomes after isolated TV surgery with a specific focus on PPI requirements.
Methods:
Three databases were assessed. The primary outcome was the rate of postoperative PPI. Secondary endpoints included short-term and long-term survival, cardiopulmonary bypass (CPB) and procedural duration, intensive care unit (ICU) and hospital stay, and postoperative stroke incidence. Hazard ratios, odds ratios, and 95% confidence intervals were calculated. A pooled Kaplan-Meier survival curve after reconstruction analysis was generated for the endpoint of long-term survival. Random-effects models were used.
Results:
A total of 1,157 studies were identified. Six observational studies from different countries were included in the analysis. The cohorts receiving either BH or AH technique for isolated TV surgery showed no significant differences in the rate of PPI (range: 6.3% to 18.2%) or any secondary outcomes, including short-term and long-term survival, CPB and procedural duration, ICU and hospital stay, or stroke incidence.
Conclusions:
Our meta-analysis suggests that performing TV surgery on the BH is not likely to be associated with a reduced risk of postoperative PPI or with different incidences of major clinical endpoints.
