Review
PURPOSE
Aortic stenosis (AS) is a common valvular heart disease with high morbidity and mortality. Recently, the association between peak atrial longitudinal strain (PALS) and AS clinical outcomes has been identified. This systematic review evaluates the prognostic value of PALS for adverse events in AS.
METHODS
We performed a systematic literature review to identify clinical studies that evaluated Speckle-Tracking Echocardiography (STE)-derived PALS to predict adverse outcomes in patients with AS. We excluded studies that compared echocardiography to computed tomography and studies that focused on diseases other than AS.
RESULTS
We included 18 studies reporting on 2660 patients. Patients with symptomatic AS had decreased PALS when compared to patients with asymptomatic AS. Patients with AS who had adverse events had decreased PALS when compared to patients with AS with no events. Each unit increase of PALS was independently associated with decreased risk for the primary endpoint. PALS cut-off values were associated with increased risk for the primary endpoint.
CONCLUSION
This systematic review suggests PALS as an independent predictor for cardiovascular events in patients with AS and highlights the importance of evaluating LA mechanics for AS prognosis.

Meta-Analysis
BACKGROUND
Coronary pressure indices to assess coronary artery disease are currently underused in patients with aortic stenosis due to many potential physiological effects that might hinder their interpretation. Studies with varying sample sizes have provided us with conflicting results on the effect of transcatheter aortic valve replacement (TAVR) on these indices. The aim of this meta-analysis was to study immediate and long-term effects of TAVR on fractional flow reserve (FFR) and nonhyperemic pressure ratios (NHPRs).
METHODS AND RESULTS
Lesion-specific coronary pressure data were extracted from 6 studies, resulting in 147 lesions for immediate change in FFR analysis and 105 for NHPR analysis. To investigate the long-term changes, 93 lesions for FFR analysis and 68 for NHPR analysis were found. Lesion data were pooled and compared with paired tests. Immediately after TAVR, FFR decreased significantly (-0.0130±0.0406 SD, : 0.0002) while NHPR remained stable (0.0003±0.0675, : 0.9675). Long-term after TAVR, FFR decreased significantly (-0.0230±0.0747, : 0.0038) while NHPR increased nonsignificantly (0.0166±0.0699, : 0.0543). When only borderline NHPR lesions were considered, this increase became significant (0.0249±0.0441, : 0.0015). Sensitivity analysis confirmed our results in borderline lesions.
CONCLUSIONS
TAVR resulted in small significant, but opposite, changes in FFR and NHPR. Using the standard cut-offs in patients with severe aortic stenosis, FFR might underestimate the physiological significance of a coronary lesion while NHPRs might overestimate its significance. The described changes only play a clinically relevant role in borderline lesions. Therefore, even in patients with aortic stenosis, an overtly positive or negative physiological assessment can be trusted.

Review
The efficacy and safety of new-generation devices (NGDs) for severe aortic regurgitation (AR) have mostly been based on single-arm studies with limited sample sizes. Our goal was to summarize the current evidence on NGDs and compare the safety and efficacy of 'off-label' and 'on-label' devices in NGDs. We searched MEDLINE, Embase, Cochrane Library, and Scopus for articles on transcatheter aortic valve replacement in patients with AR. A total of 31 studies that included 1851 patients were identified through April 2023. Among these, 1067 (57.6%) patients received treatment with 'on-label' devices (JenaValve and J-Valve). For NGDs, the total device success rate at 30 days was 94.5% (on-label: 97.8%, off-label: 89.9%; P < 0.001), the all-cause mortality was 4.2% (on-label: 2.6%, off-label: 5.1%; P = 0.006), permanent pacemaker implantation (PPI) was 8.8% (on-label: 6.9%, off-label: 18.4%; P < 0.001), and the rate of greater-than-mild paravalvular leak (PVL) was 1.2% (on-label: 0.9%, off-label: 3.8%; P = 0.003). On-label devices showed significantly better safety and efficacy in terms of the success rate, PPI, greater-than-mild PVL, and 30 day mortality than off-label devices.

Aortic stenosis (AS) is very common in mid-aged and elderly patients, and it has been reported to have a negative impact on both short and long-term survival with a high mortality rate. The current study identified methods of diagnosis, incidence, and causes of AS, pathogenesis, intervention and management and future perspectives of Asymptomatic and Symptomatic Aortic stenosis. A systematic literature search was conducted using PubMed, Scopus and CINAHL, using the Mesh terms and key words "Aortic stenosis", "diagnostic criteria", "pathogenesis", "incidence and causes of AS" and" intervention and management strategies". Studies were retained for review after meeting strict inclusion criteria that included studies evaluating Asymptomatic and Symptomatic AS. Studies were excluded if duplicate publication, overlap of patients, subgroup studies of a main study, lack of data on AS severity, case reports and letters to editors. Forty-five articles were selected for inclusion. Incidence of AS across the studies ranged from 3 % to 7 %. Many factors have been associated with incidence and increased risk of AS, highest incidence of AS was described after aortic valve calcification, rheumatic heart disease, degenerative aortic valve disease, bicuspid aortic valve and other factors. AS is common and can be predicted by aortic root calcification volume, rheumatic heart disease, degenerative aortic valve disease, bicuspid aortic valve. Intervention and management for AS patients is a complex decision that takes into consideration multiple factors. On the other hand, there is not enough progress in preventive pharmacotherapy to slow the progression of AS.

Valve-in-Valve Transcatheter Aortic Valve Replacement Versus Redo-Surgical Aortic Valve Replacement in Patients With Aortic Stenosis: A Systematic Review and Meta-analysis.
Aortic stenosis is a common and significant valve condition requiring bioprosthetic heart valves with transcatheter aortic valve replacement (TAVR) being strongly recommended for high-risk patients or patients over 75 years. This meta-analysis aimed to pool existing data on postprocedural clinical as well as echocardiographic outcomes comparing valve-in-valve (ViV)-TAVR to redo-surgical aortic valve replacement to assess the short-term and medium-term outcomes for both treatment methods. A systematic literature search on Cochrane Central, Scopus, and Medline (PubMed interface) electronic databases from inception to August 2023. We used odds ratios (OR) for dichotomous outcomes and mean differences (MD) for continuous outcomes. Twenty-four studies (25,216 patients) were pooled with a mean follow-up of 16.4 months. The analysis revealed that ViV-TAVR group showed a significant reduction in 30-day mortality (OR 0.50, 95% confidence interval [CI] 0.43 to 0.58, p <0.00001), new-onset atrial fibrillation (OR 0.34, 95% CI 0.17 to 0.67, p = 0.002), major bleeding event (OR 0.28, 95% CI 0.17 to 0.45, p <0.00001) and lower rate of device success (OR 0.25, 95% CI 0.12 to 0.53, p = 0.0003). There were no significant differences between either group when assessing 1-year mortality, stroke, myocardial infarction, postoperative left ventricular ejection fraction, and effective orifice area. ViV-TAVR cohort showed a significantly increased incidence of paravalvular leaks, aortic regurgitation, and increased mean aortic valve gradient. ViV-TAVR is a viable short-term option for elderly patients with high co-morbidities and operative risks, reducing perioperative complications and improving 30-day mortality with no significant cardiovascular adverse events. However, both treatment methods present similar results on short-term to medium-term complications assessment.

Meta-Analysis
BACKGROUND
Stroke is a feared complication of transcatheter aortic valve replacement (TAVR). Patients undergoing TAVR typically have multiple comorbidities, such as carotid artery stenosis (CAS). We conducted the present meta-analysis to determine the risk of stroke and mortality following TAVR in patients with CAS.
METHODS
We searched PubMed/Medline, Scopus, ScienceDirect, and Cochrane Clinical Trials databases for clinical studies that compared CAS ≥50% and CAS ≥70% versus non-CAS TAVR population. The endpoints included the 30-day incidence of stroke or transient ischemic attack (TIA) and 30-day all-cause of mortality.
RESULTS
We identified seven studies that included 12,418 patients in the CAS group and 102,316 in the control group. CAS ≥50% was not associated with an increased risk of 30-day stroke or TIA after TAVR [risk ratio (RR): 1.38; 95% confidence interval (95% CI): 0.95-2.02; p = 0.09]. However, patients with CAS ≥70% had an increased risk of stroke or TIA (RR: 1.43; 95% CI: 1.02-2.01; p = 0.04). No difference in 30-day all-cause mortality was observed between CAS ≥50% or CAS ≥70% and control groups (RR: 1.09; 95% CI: 0.79-1.52; p = 0.59 and RR: 1.11; 95% CI: 0.85-1.45; p = 0.43, respectively).
CONCLUSIONS
CAS ≥70% was associated with an increased risk of stroke or TIA following TAVR compared with patients without CAS.

Moderate Aortic Valve Stenosis Is Associated With Increased Mortality Rate and Lifetime Loss: Systematic Review and Meta-Analysis of Reconstructed Time-to-Event Data of 409 680 Patients.
BACKGROUND
The mortality risk attributable to moderate aortic stenosis (AS) remains incompletely characterized and has historically been underestimated. We aim to evaluate the association between moderate AS and all-cause death, comparing it with no/mild AS (in a general referral population and in patients with heart failure with reduced ejection fraction).
METHODS AND RESULTS
A systematic review and pooled meta-analysis of Kaplan-Meier-derived reconstructed time-to-event data of studies published by June 2023 was conducted to evaluate survival outcomes among patients with moderate AS in comparison with individuals with no/mild AS. Ten studies were included, encompassing a total of 409 680 patients (11 527 with moderate AS and 398 153 with no/mild AS). In the overall population, the 15-year overall survival rate was 23.3% (95% CI, 19.1%-28.3%) in patients with moderate AS and 58.9% (95% CI, 58.1%-59.7%) in patients with no/mild aortic stenosis (hazard ratio [HR], 2.55 [95% CI, 2.46-2.64]; <0.001). In patients with heart failure with reduced ejection fraction, the 10-year overall survival rate was 15.5% (95% CI, 10.0%-24.0%) in patients with moderate AS and 37.3% (95% CI, 36.2%-38.5%) in patients with no/mild AS (HR, 1.83 [95% CI, 1.69-2.0]; <0.001). In both populations (overall and heart failure with reduced ejection fraction), these differences correspond to significant lifetime loss associated with moderate AS during follow-up (4.4 years, <0.001; and 1.9 years, <0.001, respectively). A consistent pattern of elevated mortality rate associated with moderate AS in sensitivity analyses of matched studies was observed.
CONCLUSIONS
Moderate AS was associated with higher risk of death and lifetime loss compared with patients with no/mild AS.

Review
Efficacy and outcomes of antiplatelet therapy versus oral anticoagulants in patients undergoing transcatheter aortic valve replacement: a systematic review and meta-analysis.
BACKGROUND
Recent guidelines suggest that antiplatelet therapy (APT) is the standard of care in the absence of long-term oral anticoagulation (OAC) indications in patients post-transcatheter aortic valve replacement (TAVR). The superiority of one method over the other remains controversial.
MATERIALS AND METHODS
Several databases, including MEDLINE, Google Scholar, and EMBASE, were electronically searched. The primary endpoint was the all-cause mortality (ACM) rate. Secondary endpoints included cardiovascular death, myocardial infarction (MI), stroke/TIA, haemorrhagic stroke, bleeding events, systemic embolism, and valve thrombosis in post-TAVR patients receiving APT and oral anticoagulants (OACs). Forest plots were generated using Review Manager version 5.4, with a value less than 0.05 indicating statistical significance. Subgroup analysis was performed to explore potential sources of heterogeneity.
RESULTS
Twelve studies were selected. No significant differences were observed in APT and OAC group for ACM [risk ratio (RR): 0.67; 95% CI:0.45-1.01; =0.05], cardiovascular death [RR:0.91; 95% CI:0.73-1.14; =0.42], MI [RR:1.69; 95% CI:0.43-6.72; =0.46], Stroke/TIA [RR:0.79; 95% CI:0.58-1.06; =0.12], ischaemic stroke [RR:0.83; 95% CI:0.50-1.37; =0.47], haemorrhagic stroke [RR:1.08; 95% CI: 0.23-5.15; =0.92], major bleeding [RR:0.79; 95% CI:0.51-1.21; =0.28], minor bleeding [RR:1.09; 95% CI: 0.80-1.47; =0.58], life-threatening bleeding [RR:0.85; 95% CI:0.55-1.30; =0.45], any bleeding [RR:0.98; 95% CI:0.83-1.15; =0.78], and systemic embolism [RR:0.87; 95% CI:0.44-1.70; =0.68]. The risk of valve thrombosis was higher in patients receiving APT than in those receiving OAC [RR:2.61; 95% CI:1.56-4.36; =0.0002].
CONCLUSIONS
Although the risk of valve thrombosis increased in patients receiving APT, the risk of other endpoints was comparable between the two groups.

BACKGROUND
Subclinical hypothyroidism (SCH) is associated with major adverse cardiovascular events. Despite the recognized negative impact of SCH on cardiovascular health, research on cardiac postoperative outcomes with SCH has yielded conflicting results, and patients are not currently treated for SCH before cardiac surgery procedures.
METHODS
We performed a study-level meta-analysis on the impact of SCH on patients undergoing nonurgent cardiac surgery, including coronary artery bypass grafting and valve and aortic surgery. The primary outcome was operative mortality. Secondary outcomes were hospital length of stay (LOS), intensive care unit (ICU) stay, postoperative atrial fibrillation (POAF), intra-aortic balloon pump (IABP) use, renal complications, and long-term all-cause mortality.
RESULTS
Seven observational studies, with a total of 3445 patients, including 851 [24.7%] diagnosed with SCH and 2594 [75.3%] euthyroid patients) were identified. Compared to euthyroid patients, the patients with SCH had higher rates of operative mortality (odds ratio [OR], 2.57; 95% confidence interval [CI], 1.09-6.04; = .03), prolonged hospital LOS (standardized mean difference, 0.32; 95% CI, 0.02-0.62; = .04), a higher rate of renal complications (OR, 2.53; 95% CI, 1.74-3.69; < .0001), but no significant differences in ICU stay, POAF, or IABP use. At mean follow-up of 49.3 months, the presence of SCH was associated with a higher rate of all-cause mortality (incidence rate ratio, 1.82; 95% CI, 1.18-2.83; = .02).
CONCLUSIONS
Patients with SCH have higher operative mortality, prolonged hospital LOS, and increased renal complications after cardiac surgery. Achieving and maintaining a euthyroid state prior to and after cardiac surgery procedures might improve outcomes in these patients.

Improved tricuspid regurgitation after transcatheter aortic valve replacement is associated with better survival: Systematic review and meta-analysis with reconstructed time-to-event data.
BACKGROUND
This meta-analysis compared survival outcomes among patients experiencing improvement in untreated significant tricuspid regurgitation (TR) following transcatheter aortic valve replacement (TAVR) for severe aortic stenosis, in contrast to those without improvement.
METHODS
MEDLINE and EMBASE were searched through January 2024. Pooled hazard ratios (HR) with 95% confidence intervals (CI) were computed. Employing network meta-analysis, a comparison involving four post-procedural TR categories (improved, no improvement, worsened, and no change) was executed. Subsequently, these categories were amalgamated into two groups (less TR after TAVR and same or greater TR after TAVR), and a standard meta-analysis was conducted. Kaplan-Meier curves depicting long-term all-cause mortality were reconstructed utilizing individual patient data derived from the studies.
RESULTS
A systematic review identified seven non-randomized studies encapsulating 698 patients. Network meta-analysis revealed that improved TR after TAVR correlated with significantly lower long-term all-cause mortality compared to the remaining cohorts. Similarly, pooled all-cause mortality of standard meta-analysis demonstrated significant reduction in patients whose TR was sub-baseline than those exhibiting same or greater TR after TAVR (HR [95% CI] = 0.43 [0.32-0.58], < .01). The hazard ratio, derived from reconstructed time-to-event data, showed a lower long-term all-cause mortality in patients with less TR after TAVR relative to the other cohort (HR [95% CI] = 0.46 [0.32-0.67], < .01).
CONCLUSION
This meta-analysis revealed that improved TR after TAVR correlates with superior long-term survival. The benefits of simultaneous or staged intervention on the tricuspid valve in individuals undergoing TAVR warrant validation in future investigations.
