OBJECTIVES: Older patients are more prone to postoperative morbidity and mortality after mitral valve (MV) surgery. Minimally invasive MV surgery (MIMVS) is increasingly adopted worldwide, with a potential benefit in the elderly. This study compares short-term and mid-term outcomes in patients above 70 years, undergoing MIMVS versus median sternotomy (MST), in a nationwide registry.
METHODS: All patients above 70 years undergoing primary elective MV surgery (±tricuspid valve [TV] surgery, atrial septal defect closure, rhythm surgery) between 2013 and 2021 were included. All data were extracted from the Netherlands Heart Registration. Primary outcomes were short-term morbidity, mortality, and 5-year survival.
RESULTS: In total, 1418 patients were included (MST n = 797, MIMVS n = 621). No statistically significant differences in baseline characteristics were found. Median Logistic EuroSCORE I was 6.3 [4.7-8.5] vs 6.0 [4.6-8.5], P = .27 for MST and MIMVS, respectively. Mitral valve repair (77.7% vs 64.7% P < .001) and concomitant TV surgery (43.9% vs 18.2%, P < .001) was more frequently performed in MST. Lower 30-day mortality was observed in MIMVS (0.6% [n = 4] vs 2.5% [n = 21], P = .01). Furthermore, the incidence of pneumonia, prolonged intubation, readmission to intensive care unit, kidney failure, and new-onset arrhythmia were lower for MIMVS. No difference in 5-year survival was found (MST: 89.1 ± 4.6% vs MIMVS: 91.6 ± 4.7% Log-Rank P = .51).
CONCLUSIONS: Minimally invasive MV surgery in patients above 70 years may be associated with lower 30-day mortality and incidence of postoperative complications compared with sternotomy.
