Description
Objective: Valve-sparing aortic root replacement (VSARR) is a favored method for repairing aortic root aneurysms in patients with suitable anatomy and a reasonable life expectancy, as numerous studies have demonstrated excellent long-term outcomes. Despite the increasing use of minimally invasive techniques in cardiac surgery, there is limited data on minimally invasive VSARR. This study aimed to compare the long-term survival and durability of repairs between VSARR performed via full sternotomy (FS) or ministernotomy (MS).
Methods: We gathered data prospectively of all VSARR procedures at two high-volume tertiary centers. Starting in 2014, one center adopted a MS approach for aortic root aneurysms below 65 mm. The primary endpoint was long-term mortality, while the secondary endpoint involved repair durability, measured by the degree of aortic insufficiency at the longest follow-up, perioperative complications, and the need for further intervention.
Results: Ninety-four patients were included in the study (21 in the MS group and 73 in the FS group). The median age [interquartile range, IQR] of patients was 46 [32-62], and the median EuroSCORE II was 2.48 [1.29-3,36]. The aortic cross clamp duration was 35 minutes longer in the MS group [median 160 (143-184) vs. 195 (171-212), p=0.011]. There were no differences in perioperative complications, including kidney failure requiring dialysis (p=0.399), re-exploration for bleeding (p=0.705), neurological complications (p>0.999), or ICU stay (p=0.700). The 30-day mortality was 4.1% (3 out of 73) in FS group and 0% in MS group (p>0.999). In a median clinical follow-up of 5.1 years, there were no differences in survival between the groups (logrank test, p=0.260). Four patients (5.4%) in the FS group and no patients in MS required re-intervention during follow-up (p=0.572). Similarly, in a median echocardiographic follow-up of 2.0 years, there were no differences in the progression to ≥moderate aortic regurgitation between the groups (p>0.999).
Conclusions: Minimally invasive VSARR appears to be safe and shows comparable survival and durability to the FS approach among patients with aortic root aneurysms below 65 mm.
