STS has developed an MVRR composite performance measure that will be used for participant feedback, quality performance assessment and improvement, and voluntary public reporting.

In contemporary patients, concomitant TVr is not associated with a risk-adjusted increase in mortality, regardless of TR severity. A more liberal approach to TVr at the time of MVRR may be justified when long-term benefits are thought to outweigh incremental short-term morbidity risk. Further investigation of longitudinal TVr outcomes is warranted.

CABG mortality rates vary directly with FTR, but complication rates have little relation to death. FTR rates derived from The Society of Thoracic Surgeons data can serve as national benchmarks. Predicted FTR rates may facilitate patient counseling, and FTR O/E ratios have promise as valuable quality metrics.
