Abstract
Abstract
Background
The advantage of minimally invasive sternotomy (MS) over full sternotomy (FS) for isolated aortic valve replacement (AVR) is still controversial. We aimed to examine if J-shaped MS is a safe alternative to FS in patients undergoing primary isolated AVR. This study is a retrospective and restricted cohort study that included 137 patients who had primary isolated AVR from February 2013 to June 2015. Patients with previous cardiac operations, low ejection fraction (< 40%), infective endocarditis, EuroSCORE II predicted mortality > 10%, and patients who had inverted T or inverted C-MS or right anterior thoracotomy were excluded. Patients were grouped into the FS group (n=65) and MS group (n=72). Preoperative variables were comparable in both groups. The outcome was studied, balancing the groups by propensity score matching.
Results
Seven (9%) patients in the MS group were converted to FS. Cardiopulmonary bypass (98.5 ± 29.3 vs. 82.1 ± 13.95 min; p ≤ 0.001) and ischemic times (69.1 ± 23.8 vs. 59.6 ± 12.2 min; p = 0.001) were longer in MS. The MS group had a shorter duration of mechanical ventilation (10.1 ± 11.58 vs. 10.9 ± 6.43 h; p = 0.045), ICU stay (42.74 ± 40.5 vs. 44.9 ± 39.3; p = 0.01), less chest tube drainage (385.3 ± 248.6 vs. 635.9 ± 409.6 ml; p = 0.001), and lower narcotics use (25.14 ± 17.84 vs. 48.23 ± 125.68 mg; p < 0.001). No difference was found in postoperative heart block with permanent pacemaker insertion or atrial fibrillation between groups (p = 0.16 and 0.226, respectively). Stroke, renal failure, and mortality did not differ between the groups. Reintervention-free survival at 1, 3, and 4 years was not significantly different in both groups (p = 0.73).
Conclusion
J-ministernotomy could be a safe alternative to FS in isolated primary AVR. Besides the cosmetic advantage, it could have better clinical outcomes without added risk.
