We estimated the association between RAR and the primary outcome using the univariable and multivariable Cox proportional hazards regression models. For variables with missing values under 5%, the corresponding mean or median was imputed. Baseline characteristics were compared using the one-way ANOVA tests or Kruskal-Wallis H-tests for continuous variables and the chi-square or Fisher’s exact test for categorical variables. Continuous variables were presented as means ± standard deviations (SD) or median and interquartile ranges (IQR) and categorical variables as frequencies and percentages (%). The included patients were divided into three groups according to the tertiles of RAR level. Therefore, this study aimed to explore the association between RAR and all-cause mortality in patients with TAVR and to evaluate whether RAR contributes to risk stratification. However, the relationship between RAR and outcomes in patients undergoing TAVR is uncertain. RAR is a better prognostic marker than either albumin or RDW alone in patients with heart failure, stroke, cancer, aortic aneurysms, diabetic ketoacidosis, and diabetic foot. Linking RDW and nutritional parameters better reflects the geriatric characteristics of these patients. The RDW-to-albumin ratio (RAR), an innovative and comprehensive biomarker, combines systemic inflammation and nutritional status to reflect essential aspects of frailty. Previous research has found that hypoalbuminemia is a powerful predictor of post-TAVR death. Besides, albumin, a known marker for frailty, was related to malnutrition and chronic inflammation. also reported that a baseline of higher RDW and growing RDW were substantially associated with a higher risk of mortality in TAVR patients. Moreover, RDW was an independent predictor of frailty in older adults with coronary heart disease. Recent research has found a link between red cell distribution width (RDW) and the body’s systemic inflammatory response. Studies have shown that inflammation is linked with the progression of aortic valve disease and frailty. Accurate frailty assessment may reduce mortality and readmissions after TAVR.

This can assist clinicians in risk-stratifying TAVR patients and making timely individualized interventions.įrailty is an aging syndrome that frequently occurs in elderly individuals and increases the risk of mortality and disability in the population undergoing TAVR. Therefore, as more patients qualify for TAVR, identifying high-risk patients becomes increasingly essential. Although TAVR benefits many patients in terms of survival and symptoms, some patients have died or been readmitted within one year of the procedure. Further studies may be needed to examine whether indeed the flutter device can be of additional benefit to preventing post-operative pulmonary complications.With the improvement of operator techniques and medical technology, the indications for transcatheter aortic valve replacement (TAVR) are expanding to patients with moderate and low surgical risk, making it an acceptable alternative to surgical aortic valve replacement. This was attributed to the small sample size and to the 'dilution' effect of subjecting both groups to incentive spirometry. In the end, there were no differences noted between those who just received incentive spirometry as compared to those who also underwent use of the flutter device, using several clinical and laboratory parameters.

In addition, 17 were also taught how to use the flutter device All were subjected to incentive spirometry and post-operative pulmonary rehabilitation. A total of 31 patients who had undergone upper abdominal surgery (cholecystectomy) were included. However, unlike the blow bottle, its unique metal ball valve design intermittently opens and closes at a rapid rate, thus producing not only alveolar inflation but also an oscillating pressure across the airways. The flutter (VRP1) device is a new device that creates increased positive alveolar pressures thus producing lung inflation just like the blow bottle. One of the newer approaches is examined in this study.

At the moment, so-called incentive spirometry remains the standard by which effectiveness of new treatments are evaluated. Even up to this time there remains no single effective intervention that could eliminate this situation. Pulmonary complications post-operatively are quite common.
