Objectives: The aim of this study is to investigate the role and short-term results of balloon aortic valvuloplasty (BAV) before noncardiac surgery in a high selected cohort of patients.
Background: Aortic stenosis is one of the most common valvular heart diseases and a well recognized risk factor for perioperative mortality.
Methods: Between May 2012 and July 2013 we enrolled 15 consecutive patients with severe aortic stenosis to allow urgent major noncardiac surgery. They had been excluded from surgical aortic valve replacement and transcatheter aortic valve implantation.
Results: Fifteen patients underwent BAV as a bridge to noncardiac surgery. They were elderly (mean age 81 ± 5 years) and predominantly men (66%) with high surgery risk (mean logistic EuroSCORE: 31.1 ± 18.2%). Three patients underwent vascular surgery, five underwent thoracic surgery, five were subjected to major abdominal surgery and in the last two patients orthopedic surgery and mastectomy were performed. No adverse events were observed in the perioperative period. Six patients (40%) were in New York Heart Association class III or IV. Mean aortic valve area was 0.52 ± 0.1 cm/m; mean aortic pressure gradient was 55.6 ± 10.8 mmHg. BAV was performed successfully in all patients. The mean peak-to-peak gradient assessed by catheterization significantly reduced after BAV (from 69.0 ± 22.1 to 29.7 ± 9.3 mmHg; P < 0.0001). The echocardiographic mean gradient was also significantly improved (from 55.6 ± 10.8 to 33.8 ± 7.9 mmHg; P < 0.0001). Survival at 30 days and at 6 months' follow-up respectively was 100%. At 6 months' follow-up clinical status according to New York Heart Association class was significantly improved (P < 0.0001).
Conclusion: BAV is well tolerated and effective in high-risk patients with severe aortic stenosis undergoing noncardiac surgery with good short-term survival. It could represent a valid choice of treatment prior to noncardiac surgery in these high-risk patients.

Assessing the use of the Index of Consciousness (IoC) as a monitoring tool for the sedative effects of ciprofol during general anesthesia induction: a prospective observational study.

Background: We investigated the consistency and accuracy of the Index of Consciousness (IoC) and the Bispectral Index (BIS) in monitoring the sedative effect of ciprofol during the induction of general anesthesia. There is extensive literature that reports good consistency and correlations between the IoC1 and the BIS in reflecting the sedation levels induced by propofol and sevoflurane but not by ciprofol.
Objective: The aim was to compare the consistency and accuracy of the IoC and BIS in monitoring the sedative effect of ciprofol during the induction of general anesthesia.
Effect of different intraoperative blood pressure regulation levels on postoperative myocardial injury in patients undergoing radical mastectomy for breast cancer after receiving neoadjuvant chemotherapy: a study protocol for a randomised controlled trial.

Introduction: For patients with breast cancer receiving preoperative neoadjuvant chemotherapy with anthracyclines, there is an increased risk of postoperative myocardial injury due to the cardiotoxicity of the chemotherapeutic agents. The optimal intraoperative blood pressure regulation regimen for these patients is unclear. This study is being conducted to determine whether targeting mean arterial pressure (MAP) to 100%-120% of the patient's baseline blood pressure reduces the incidence of myocardial injury after non-cardiac surgery (MINS) compared with targeting MAP to 80%-100%.

Background: Rehabilitation therapists are sometimes unaware of the possibility of undiagnosed atrial fibrillation (AF) and the importance of AF detection. Thus, we aimed to increase awareness among rehabilitation therapists of the importance of AF detection at rehabilitation hospitals during regular pulse checks of patients with ischemic stroke.
Methods: In this multicenter prospective observational study, we enrolled patients with noncardiac stroke.

Background: Optimised use of kidney function information might improve cardiac risk prediction in noncardiac surgery.
Methods: In 35,815 patients from the VISION cohort study and 9219 patients from the POISE-2 trial who were ≥45 yr old and underwent nonurgent inpatient noncardiac surgery, we examined (by age and sex) the association between continuous nonlinear preoperative estimated glomerular filtration rate (eGFR) and the composite of myocardial injury after noncardiac surgery, nonfatal cardiac arrest, or death owing to a cardiac cause within 30 days after surgery. We estimated contributions of predictive information, C-statistic, and net benefit from eGFR and other common patient and surgical characteristics to large multivariable models.
Individualised acute normovolaemic haemodilution for non-cardiac surgery with anticipated high-dose red cell transfusion: study protocol for a randomised controlled trial in West China Hospital of Sichuan University.

Introduction: Acute normovolaemic haemodilution (ANH) is a perioperative blood management technique involving the removal of whole blood and simultaneous infusion of colloids or crystalloids to achieve haemodilution while maintaining normovolaemia. However, its efficacy in reducing the requirement for perioperative allogeneic blood transfusion remains controversial due to inconsistent findings in the literature. An individualised red cell transfusion strategy, guided by the West China Liu's Score, has demonstrated effectiveness in reducing the need for allogeneic red cell transfusion.
