Meta-Analysis
Comparing functional and quality of life outcomes in transcatheter aortic valve implantation and surgical aortic valve replacement for aortic stenosis: a systematic review and meta-analysis.
BACKGROUND
To compare functional and health related quality of life outcomes post-transcatheter aortic valve implantation (TAVI) and surgical aortic valve replacement (SAVR) in patients with critical aortic stenosis (AS) across low to high-risk surgical candidates. These patient-centred factors will be compared between both groups in the short to medium term time frames and will aid in shared decision making between patients and healthcare workers.
MATERIALS AND METHODS
We conducted a systematic review and meta-analysis of randomised controlled trials which compared TAVI with SAVR and reported on quality of life (QoL) and functional scores. The scores used were the Kansas City Cardiomyopathy Questionnaire (KCCQ), Euroqol-5DL (EQ5DL), the short form-36/12 (SF-36/12) and the NYHA.
RESULTS
We identified eight trials with a total of 8898 participants. Both groups showed improvements from baseline at one month. At one month there was a statistically significant difference in standardised mean difference (SMD) in favour of TAVI for EQ5DL (SMD 0.37, 95% CI 0.26,0.49), KCCQ (SMD 0.53,95% CI 0.48, 0.58), SF physical summary (SMD 0.55, 95% CI 0.31 - 0.78) and SF mental summary (SMD 0.34, 95% CI 0.27 - 0.40). At one year there was no statistically significant difference between any of these QoL metrics. For NYHA, no significant difference in odds ratio of class III/IV was observed at one month between TAVI and SAVR (OR 0.94, 95% CI 0.83, 1.07), however, TAVI was associated with reduced odds ratio of NYHA class I/II at one year (OR 0.87, 95% CI 0.78, 0.98).
CONCLUSION
Both groups were associated with improvements in QoL and functional outcomes with TAVI reporting more significant improvements in QoL at one-month post-procedures. No significant improvements between groups were seen at one year. This is the largest meta-analysis comparing post-operative health-related quality of life outcomes post SAVR and TAVI and has major implications in shared decision making for the treatment of aortic stenosis.

Meta-Analysis
Comparisons of different new-generation transcatheter aortic valve implantation devices for patients with severe aortic stenosis: a systematic review and network meta-analysis.
BACKGROUND
Whether there are differences among the new-generation transcatheter aortic valve implantation (TAVI) devices for patients with aortic stenosis remains unclear. The aim of the study was to compare the efficiency and safety of different new-generation TAVI devices for patients with aortic stenosis.
MATERIALS AND METHODS
A comprehensive search of PubMed, Embase and Web of Science from their inception to 1 February 2022. Randomized clinical trials and observational studies that compared two or more different TAVI devices were enroled. Pairwise meta-analysis and frequentist network meta-analysis were conducted to pool the outcome estimates of interest.
RESULTS
A total of 79 studies were finally included. According to the surface under the cumulative ranking, the top two ranked valves for lower rates of events were as follows: direct flow medical (DFM) (4.6%) and Lotus (48.8%) for lower rate of device success; Sapien 3 (16.8%) and DFM (19.7%) for lower mortality; DFM (8.6%) and Sapien 3 (25.5%) for lower rates of stroke; Evolut (27.6%) and DFM (35.8%) for lower rates of major and life-threatening bleeding; Portico (22.6%) and Sapien 3 (41.9%) for lower rates of acute kidney injury; Acurate (8.6%) and DFM (13.2%) for lower rates of permanent pacemaker implantation; Lotus (0.3%) and Sapien 3 (22.7%) for lower rates of paravalvular leak; Evolut (1.4%) and Portico (29.1%) for lower rates of mean aortic valve gradients.
CONCLUSIONS
The findings of the present study suggested that the device success rates were comparable among these new-generation valves except for DFM. After excluding DFM, Sapien 3 might be the best effective for decreased mortality and stroke; Lotus might be the best effective for decreased paravalvular leak; Evolut might be the best effective for decreased major and life-threatening bleeding and mean aortic valve gradients; Acurate and Portico might be the best effective for decreased permanent pacemaker implantation and acute kidney injury, respectively.

Meta-Analysis
BACKGROUND
Currently, transcatheter aortic valve implantation (TAVI) is presently a recognized treatment modality for patients with severe aortic stenosis who are often old, disabled, frail, and have low exercise capacity (ExCap). It is further expected from this therapy to improve quality of life by improving of the cardio function performance. The aim of this study is to evaluate the effect of exercise-based cardiac rehabilitation (CR) on patients after TAVI.
METHODS
PubMed, Embase, Cochrane Library, and Web of Science were searched from inception to December 10, 2022 for relevant studies that evaluated the effect of CR on patients after TAVI. The primary outcome was the improvement of 6-minute walked distance and Barthel index score after CR. The secondary outcomes included other parameters such as SF-12 scale, HADS score, Morse Fall Scale, Frailty-Index, ExCap, and FIM score. All statistical analyses were performed using the standard statistical procedures provided in Review Manager 5.2.
RESULTS
A total of 12 observational studies were identified, with 2365 participants. Pooled data indicated that CR programmers significantly improved the 6-minute walked distance (SMD 0.65; 95% confidence intervals [CI] 0.51-0.79) and Barthel index score (SMD 0.83; 95% CI 0.61-1.06). In addition, compared with admission, patients experienced significant improvement in SF-12 scale at CR discharge, with a pooled mean differences (MD) of 2.74 (95% CI 0.86-4.61) in physical component score and 2.76 (95% CI 0.59-4.93) in mental component score. Similar results were also observed in ExCap (MD 8.10 W; 95% CI 1.57 W-14.63 W) and FIM score (MD 11.0; 95% CI 6.22-15.78).
CONCLUSIONS
Our analysis indicated that exercise-based CR programmers had significant effect on patients after TAVI in improving exercise tolerance and functional independence.

Meta-Analysis
AIMS
The mortality risk of patients with moderate aortic stenosis is not well known, but recent studies suggested that it might negatively affect prognosis. We aimed to assess the natural history and clinical burden of moderate aortic stenosis and to investigate the interaction of patients' baseline characteristics with prognosis.
METHODS
Systematic research was conducted on PubMed. The inclusion criteria were inclusion of patients with moderate aortic stenosis; and report of the survival at 1-year follow-up (minimum). Incidence ratios related to all-cause mortality in patients and controls of each study were estimated and then pooled using a fixed effects model. All patients with mild aortic stenosis or without aortic stenosis were considered controls. Meta-regression analysis was performed to assess the impact of left ventricular ejection fraction and age on the prognosis of patients with moderate aortic stenosis.
RESULTS
Fifteen studies and 11 596 patients with moderate aortic stenosis were included. All-cause mortality was significantly higher among patients with moderate aortic stenosis than in controls in all timeframes analysed (all P < 0.0001). Left ventricular ejection fraction and sex did not significantly impact on the prognosis of patients with moderate aortic stenosis ( P = 0.4584 and P = 0.5792), while increasing age showed a significant interaction with mortality (estimate = 0.0067; 95% confidence interval: 0.0007-0.0127; P = 0.0323).
CONCLUSION
Moderate aortic stenosis is associated with reduced survival. Further studies are necessary to confirm the prognostic impact of this valvulopathy and the possible benefit of aortic valve replacement.

OBJECTIVE
Subclinical leaflet thrombosis (SLT) develops in 15% of patients undergoing trans-catheter aortic valve replacement (TAVR). TAVR is a procedure in which a faulty aortic valve is replaced with a mechanical one. An aortic valve replacement can be done with open-heart surgery; this is called surgical aortic valve replacement (SAVR). A significant problem is defining the best course of treatment for asymptomatic individuals with SLT post-TAVR, including the use of oral anticoagulation (OAC) in it.
STUDY DESIGN
Systematic review.
METHOD
The most pertinent published research (original papers and reviews) in the scientific literature were searched for and critically assessed using the online, internationally indexed databases PubMed, Medline, and Cochrane Reviews. Keywords like "Transcatheter valve replacement" and "Subclinical leaflet thrombosis" were used to search the papers. Selected studies were critically assessed for inclusion based on predefined criteria.
RESULTS
The review examined the prevalence and characteristics of SLT after TAVR. To note, the incidence of SLT is seen to be higher in TAVR compared SAVR. Dual antiplatelet therapy, which is utilized in antithrombotic regimens post-TAVR, can possibly hasten SLT progression which could result in the impaired mobility of leaflets and the worsening of pressure gradients.
CONCLUSION
The use of dual antiplatelet drugs in routine antithrombotic therapy tends to accelerate initial subclinical leaflet thrombosis after TAVI, which results in a developing restriction of leaflet mobility and an increase in pressure differences.

Meta-Analysis Review
Recent randomised trials have shown that clinical outcomes with transcatheter aortic valve implantation (TAVI) are non-inferior to surgical aortic valve replacement (SAVR) in patients with symptomatic aortic stenosis at intermediate to low risk. Health-related quality of life (HrQoL) outcomes in these patient groups remain uncertain. A systematic search of the literature was conducted that included nine trials and 11,295 patients. Kansas City Cardiomyopathy Questionnaire (KCCQ), a heart-failure-specific measure and EuroQol-5D (EQ-5D) (a generic health status tool) changes were the primary outcomes. New York Heart Association (NYHA) classification was the secondary outcome. Improvement in KCCQ scores was greater with TAVI (mean difference (MD)=13.56, 95% confidence interval (CI) 11.67-15.46, p<0.001) at 1 month, as was the improvement in EQ-5D (MD=0.07, 95% CI 0.05-0.08, p<0.001). There was no difference in KCCQ (MD=1.05, 95% CI -0.11 to 2.21, p=0.08) or EQ-5D (MD=-0.01, 95% CI -0.03 to 0.01), p=0.37) at 12 months. NYHA functional class 3/4 was lower in patients undergoing TAVI at 1 month (MD=0.51, 95% CI 0.34-0.78, p=0.002), but there was no difference at 12 months (MD=1.10; 95% CI 0.87-1.38, p=0.43). Overall, TAVI offers early benefit in HRQoL outcomes compared with SAVR, but they are equivalent at 12 months.

Review
Transcatheter aortic valve replacement (TAVR) is currently the treatment of choice for patients aged ≥75 years with severe aortic stenosis. Preoperative anemia is present in a large proportion of patients and may increase the risk of post-procedural complications. The purpose of this prognostic systematic review was to analyze the impact of baseline anemia on short- and mid-term outcomes following TAVR. A computerized search was performed on PubMed and Web of Science databases for studies published between January 2013 and December 2022. Primary outcomes were 30-day need for transfusion, acute renal failure, 30-day and mid-term mortality, and readmission during the first year post-TAVR. Data were analyzed via random effects model using inverse variance method with 95% confidence intervals. Eleven observational studies met our eligibility criteria and included a total of 12,588 patients. The prevalence of baseline anemia ranged between 39% and 72%, with no relevant sex differences. Patients with preprocedural anemia received more blood transfusions [OR: 2.95 (2.13-4.09)]), and exhibited increased rates of acute kidney injury [OR:1.74 (1.45-2.10)], short-term mortality [OR: 1.47 (1.07-2.01], and mid-term [OR: 1.89 (1.58-2.25)] mortality following TAVR compared with those without anemia. Baseline anemia determined an increased risk for blood transfusion, acute kidney injury, and short/mid-term mortality among TAVR recipients.

Review
The aim of this meta-analysis is to assess the effect of different independent predictors on acute kidney injury (AKI) after transcatheter aortic valve implantation (TAVI). This meta-analysis adhered to the guidelines of the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA). A comprehensive database search was conducted using PubMed, Web of Science, and Scopus for the period from January 1, 2015, to August 15, 2023. The following key terms were employed: "transcatheter aortic valve implantation" OR "transcatheter aortic valve replacement" AND "acute kidney injury" OR "acute renal failure." Our search was limited to studies published exclusively in the English language. The statistical analysis was conducted using RevMan version 5.4.1 (The Cochrane Collaboration). Estimates were presented as odds ratio (OR) with 95% confidence interval (CI) for categorical variables, while continuous variables were reported as mean difference (MD) with 95% CI. A total of 19 studies met the selection criteria and were included in the meta-analysis. The pooled incidence of AKI was reported as 20% (95% CI: 18-20%). Factors significantly associated with post-TAVI AKI encompass hypertension, chronic kidney disease (CKD), low estimated glomerular filtration rate (eGFR), high baseline creatinine levels, peripheral vascular disease (PVD), Society of Thoracic Surgeons (STS) score, European System for Cardiac Operative Risk Evaluation (EUROscore) II, and the transfemoral surgical approach.

Review
BACKGROUND
In 2014, Ozaki introduced the neo-cuspidation (Ozaki procedure), a new valve from the pericardium, to reduce or even prevent the risk of chronic autoimmune inflammation and subsequent rejection or valve degeneration. Thus, the authors aimed to assess the safety and efficacy of the Ozaki technique in treating aortic valve diseases.
MATERIALS AND METHODS
A comprehensive search was performed via PubMed, the Cochrane Library, Scopus, and the Web of Science up to 20 February 2022. Random-effects meta-analysis models were employed to estimate the pooled mean and SD or event to the total of the Ozaki procedure. Relevant records were retrieved and analyzed by OpenMeta analyst software.
RESULTS
A total of 2863 patients from 21 studies were finally included in our analysis. Ac. Ozaki technique showed statistical significance in terms of mean cardiopulmonary bypass time of 148 mins (95% CI 144-152.2, <0.001), mean aortic cross-clamp time of 112.46 mins (95% CI 105.116, 119.823, <0.001), reoperation with a low risk of 0.011 (95% CI 0.005, 0.016, =0.047), conversion to aortic valve replacement with a low risk of 0.004 (95% CI -0.001, 0.008, =0.392), finally ICU stay (days) and hospital length of stay (days) with a mean of 2.061 days (95% CI 1.535, 2.587, <0.001) and 8.159 days (95% CI 7.183-9.855, <0.001), respectively.
CONCLUSION
The Ozaki procedure provides a safe surgical technique with low mean cardiopulmonary bypass time and aortic cross-clamp time; moreover, a mean of 2-day-postoperative hospital stay was observed with the Ozaki procedure with a low risk of conversion to aortic valve replacement, reoperation, ICU and hospital stay, and death.

Meta-Analysis Review
Transcatheter aortic valve replacement (TAVR) has become a widely used therapy for patients with severe aortic stenosis. Carbohydrate antigen 125 (CA-125) is a promising biomarker in some cardiovascular diseases. This systematic review aims to assess the prognostic role of CA-125 in patients undergoing TAVR. We searched electronic databases from inception to March 2023 to include cohort studies evaluating the association between preprocedural CA-125 levels and mortality or heart failure (HF) readmission at 12 months in patients undergoing TAVR. We pooled crude (cHR) and adjusted hazard ratios (aHR) with their 95% confidence interval (CI) using a random-effects model. The risk of bias was evaluated using the QUIPS tool. The certainty of the evidence was assessed using the GRADE approach. We included five cohort studies involving 1594 patients. Higher levels of CA-125 were significantly associated with an increased risk of mortality or HF readmission using crude (cHR 2.79, 95% CI 1.45-5.36, I = 72%) and adjusted (aHR 3.27, 95% CI 2.07-5.18, I = 0%, high certainty) effect estimates compared with lower levels. Similarly, there was also associated with increased mortality using crude (cHR 2.68, 95% CI 1.99-3.60, I = 0%) and adjusted (aHR 2.17, 95% CI 1.54-3.07, I = 0%, high certainty) effect estimates. The risk of bias varied between low to moderate across studies. Our meta-analysis suggests that CA-125 has incremental prognostic value in patients undergoing TAVR. Further studies are needed to determine the clinical utility of CA-125 in guiding treatment decisions in this population.
