Objective To compare perioperative outcomes of minimally invasive aortic valve surgery by a right anterior minithoracotomy (RAMT) and conventional sternotomy. Methods A retrospective analysis of patients who underwent isolated aortic valve surgeries in our hospital between May 2021 and August 2023 with a minimal incision via the right anterior minithoracotomy approach (a RAMT group) or conventional incision via the full sternotomy approach (a conventional group). A propensity score-matching analysis was performed to balance preoperative data and compare perioperative data of the two groups. ResultsThere were 58 patients in the RAMT group, including 46 males and 12 females with an average age of 52.0±14.1 years; 128 patients were enrolled in the conventional group, including 87 males and 41 females with an average age of 60.0±12.4 years. After propensity-score matching, there were 51 patients in each group. The RAMT patients had a longer mean operation time, cross-clamping time and cardiopulmonary bypass time compared to the conventional group (all P<0.05). However, ICU length of stay, ventilator-assisted time and postoperative hospital stay were significantly shorter in the RAMT group (all P<0.05). Patients in the RAMT group had lower 24 hour chest drain output (P<0.05). RAMT was associated with a trend towards a lower blood transfusion rate in comparison to the sternotomy group, although this was not statistically significant (P>0.05). The occurrence of all-cause death, stroke and perioperative complications was also similar in both groups (P>0.05). Conclusion Right anterior mini-thoracotomy is associated with less trauma, faster recovery, less postoperative drainage, and shorter hospital stay than conventional approach. Right anterior mini-thoracotomy in patients undergoing isolated aortic valve surgery is a safe approach and can be performed by a wide range of surgeons.
Objective To compare and analyze the early- to mid-term outcomes of transcatheter aortic valve replacement (TAVR) combined with percutaneous coronary intervention (PCI) versus surgical aortic valve replacement (SAVR) combined with coronary artery bypass grafting (CABG) for the treatment of significant aortic stenosis (AS) and coronary artery disease (CAD). Methods The data of patients with significant AS and CAD who underwent surgical treatment at Central China Fuwai Hospital of Zhengzhou University from January 2018 to July 2023 were collected. These patients were divided into a TAVR+PCI group and a SAVR+CABG group according to the operation method. Propensity score matching (PSM) was used to select patients with close clinical baseline characteristics, and the early- to mid-term outcomes of the two groups were compared. Results A total of 272 patients were enrolled, including 208 males and 64 females, with a mean age of 64.16±8.24 years. There were 47 patients in the TAVR+PCI group and 225 patients in the SAVR+CABG group. After 1∶1 PSM, 32 pairs were selected. There was no statistical difference in baseline data between the two groups (P>0.05). Compared with the SAVR+CABG group, the TAVR+PCI group had significantly shorter operative time, mechanical ventilation time, ICU stay, postoperative hospital stay, and less intraoperative bleeding, and significantly lower postoperative transfusion and complete revascularization rates (P<0.05). The differences in the rates of postoperative in-hospital death, myocardial infarction, stroke, and other complications between the two groups were not statistically significant (P>0.05), and the differences in the rates of severe perivalvular leakage, death, or readmission in the mid-term follow-up were not statistically significant (P>0.05). Conclusion In patients with significant AS and CAD, the early- and mid-term rates of death and complications were similar between those treated with TAVR+PCI and SAVR+CABG, and TAVR+PCI is a safe alternative to SAVR+CABG.
ObjectiveTo explore the clinical efficacy of robot-assisted coronary artery bypass grafting through a small incision in the left intercostal space in the treatment of multivessel coronary disease. MethodsA retrospective analysis was conducted on the clinical data of patients who underwent coronary artery bypass grafting through a small incision in the left intercostal space at Central China Fuwai Hospital of Zhengzhou University from January 1, 2023 to October 15, 2024. Patients were divided into a robotic group and a minimally invasive group based on whether the surgery was assisted by the Da Vinci robot. ResultsA total of 81 patients were included, with 57 in the minimally invasive group, including 41 males and 16 females, with a median age of 65.0 (57.5, 69.5) years; and 24 in the robotic group, including 17 males and 7 females, with a median age of 61.0 (56.0, 69.0) years. There was no statistically significant difference in baseline data between the two groups (P>0.05). The robotic group had less intraoperative bleeding [300 (200, 438) mL vs. 500 (375, 600) mL, P=0.006], shorter postoperative mechanical ventilation time [15.0 (13.3, 23.5) h vs. 22.0 (15.5, 39.5) h, P=0.037], and lower incidence of postoperative pain [8 (33.3%) vs. 33 (57.9%), P=0.043]. The hospitalization cost in the robotic group was higher than that in the minimally invasive group [130491 (123298, 135691) yuan vs. 123892 (115543, 133449) yuan, P=0.023]. There was no statistical difference in postoperative laboratory indicators between the two groups (P>0.05). There was also no statistical difference in the duration of surgery, postoperative 24 h drainage volume, ICU stay time, postoperative hospital stay or incidences of perioperative compications including pleural effusion, transfusion, new-onset atrial fibrillation, acute kidney injury, non-union of incision, major cardiovascular and cerebrovascular adverse events, and reoperation between the two groups (P>0.05). ConclusionCompared with the minimally invasive group, the robotic group shows satisfactory efficacy and can effectively reduce postoperative pain and intraoperative bleeding, and shorten postoperative mechanical ventilation time.
