Comparison between mitral valve and concomitant mitral with tricuspid valve operations: A retrospective
analysis
Steven T Leung
Wake Forest Baptist Medical Center, USA
Background:
Differences in opinion for the treatment of
tricuspid regurgitation secondary to mitral regurgitation
exist. This study compares the mortality and morbidity of
concomitant mitral and tricuspid valve operations to mitral
valve operations alone.
Methods:
Between 2004 and 2012, 153 mitral valve
operations were performed. In this group, 130 patients
(age, 58.2±13.6) underwent mitral valve repair only, and 23
patients (age, 70.6±7.7) underwent joint mitral and tricuspid
valve repairs. The results between these two groups were
compared using Pearson’s chi-square and propensity score
analyses.
Results:
Patients undergoing combined valve operations
were more elderly (ages 58.2 vs 70.6, p<0.001), and more
commonly female (73.9% vs 44.6%, p=0.010). When
performing Pearson chi-squared test, the combined valvular
operation group had a similar operative mortality (0.0% vs
1.5%, higher incidence of prolonged ventilation (30.4% vs
11.5%, p=0.017), and higher postoperative length of stay
(9.7 days vs 6.4 days, p=0.039). On the contrary, there were
no statistically significant differences in major complications
rate (43.5% vs 16.2%, p=0.103) or aortic cross-clamp time
(114.9 min vs 119.7 min, p=0.566) between the two groups.
However, due to the disparity between our two groups,
propensity score analyses were also performed, which
did not demonstrate any differences between outcomes
measured in this study.
Conclusions:
The postoperative mortality and morbidity
is similar between patients undergoing mitral valve repair
only and patients undergoing mitral and tricuspid valve
repairs. Given the decreased quality of life from progressing
tricuspid regurgitation and similar postoperative mortality
and morbidity rates, a concomitant valvular procedure is
a reasonable approach for selected patients with severe
tricuspid regurgitation secondary to mitral valve pathology.
