Transcatheter edge-to-edge repair in mitral regurgitation: A comparison of device systems and recommendations for tailored device selection. A systematic review and meta-analysis.
BACKGROUND
Mitral valve transcatheter edge-to-edge repair (M-TEER) is a minimally invasive method for the treatment of mitral regurgitation (MR) in patients with prohibitive surgical risks. The traditionally used device, MitraClip, showed both safety and effectiveness in M-TEER. PASCAL is a newer device that has emerged as another feasible option to be used in this procedure.
METHODS
We searched for observational studies that compared PASCAL to MitraClip devices in M-TEER. The electronic databases searched for relevant studies were PubMed/MEDLINE, Scopus, and Embase. The primary outcomes were technical success and the grade of MR at follow-up. Secondary outcomes included all-cause mortality, bleeding, device success and reintervention.
RESULTS
Technical success (PASCAL: 96.5% vs MitraClip: 97.6%, p = 0.24) and MR ≤ 2 at 30-day follow-up (PASCAL: 89.4vs MitraClip 89.9%, p = 0.51) were comparable between both groups. Both devices showed similar outcomes including all-cause mortality (RR: 0.68 [0.34, 1.38]; P = 0.28), major bleeding (RR: 1.87 [0.68, 5.10]; P = 0.22) and reintervention (RR: 1.02 [0.33, 3.16]; P = 0.97). Device success was more frequent with PASCAL device (PASCAL: 86% vs MitraClip 68.5%; P = 0.44), however, the results did not reach statistical significance.
CONCLUSION
Clinical outcomes of PASCAL were comparable to those of MitraClip with no significant difference in safety and effectiveness. The choice between MitraClip and PASCAL devices should be guided by various factors, including mitral valve anatomy, etiology of regurgitation, and device-specific characteristics.

Review
Structural valve deterioration after aortic root replacement (ARR) surgery may be treated by transcatheter valve-in-valve (ViV-TAVI) intervention. However, several technical challenges and outcomes are not well described. The aim of the present review was to analyze the outcomes of ViV-TAVI in deteriorated ARR. This review included studies reporting any form of transcatheter valvular intervention in patients with a previous ARR. All forms of ARR were considered, as long as the entire root was replaced. Pubmed, ScienceDirect, SciELO, DOAJ, and Cochrane library databases were searched until September 2023. Overall, 86 patients were included from 31 articles that met our inclusion criteria out of 741 potentially eligible studies. In the entire population, the mean time from ARR to reintervention was 11.0 years (range: 0.33-22). The most frequently performed techniques/grafts for ARR was homograft (67.4%) and the main indication for intervention was aortic regurgitation (69.7%). Twenty-three articles reported no postoperative complications. Six (7.0%) patients required permanent pacemaker implantation (PPI) after the ViV-TAVI procedure, and 4 (4.7%) patients had a second ViV-TAVI implant. There were three device migrations (3.5%) and 1 stroke (1.2%). Patients with previous ARR present a high surgical risk. ViV-TAVI can be considered in selected patients, despite unique technical challenges that need to be carefully addressed according to the characteristics of the previous surgery and on computed tomography analysis.

Meta-Analysis
BACKGROUND
Transcatheter edge-to-edge repair (TEER) may have potential benefits in the treatment of atrial functional mitral regurgitation (AFMR), but robust evidence is currently lacking. We conducted a systematic review and meta-analysis to investigate the clinical outcomes of TEER for AFMR, including comparisons to ventricular functional MR (VFMR).
METHODS
MEDLINE and EMBASE were searched through January 2023 to identify studies eligible for analysis. The primary outcome was postprocedural MR severity. Postprocedural New York Heart Association (NYHA) functional class classification and all-cause mortality were also evaluated. Outcomes were stratified into short term (postprocedure to 6 months) and long term (6 months to 2 years).
RESULTS
A total of eight observational studies met the inclusion criteria, enrolling 539 AFMR and 3486 VFMR patients. Postprocedural MR grade ≤2 in the AFMR group was observed in 93.7% (454/491 patients; 95% confidence interval (CI), 91.1%-96.2%, I = 24.3%) and 97.1% (89/93 patients; 95% CI, 92.9%-100%, I = 26.4%) in short- and long-term follow-up, respectively. There was no difference in the rates of postprocedural MR grade ≤2 between AFMR and VFMR either in short-term (risk ratio [RR], 1.00 [95% CI, 0.95-1.06]; p = 0.90; I = 53%) or long-term follow-up (RR, 1.08 [95% CI, 0.89-1.32]; p = 0.44; I = 22%). Similarly, no difference was observed between AFMR and VFMR in the rates of postprocedural NYHA class ≤2 or all-cause mortality.
CONCLUSION
TEER provides similar clinical outcomes for AFMR and VFMR. A high rate of MR grade ≤2 was observed in patients at both short- and long-term follow-ups. Further prospective studies with TEER versus medical therapy and/or rhythm control for AFMR are warranted.

Meta-Analysis
AIMS
In recent years, extensive literature has been produced demonstrating inferior outcomes for women when compared with men undergoing heart valve interventions. Herein, we seek to analyze the literature comparing outcomes between men and women undergoing surgical aortic valve replacement (SAVR).
METHODS
A systematic literature search of PubMed, MEDLINE, and Embase was conducted for articles comparing differences in outcomes between adult men and women undergoing SAVR. One thousand nine hundred and ninety titles were screened, of which 75 full texts were reviewed, and a total of 19 manuscripts met the inclusion criteria and were included in this review.
RESULTS
Pooled estimates of mortality demonstrated that women tended to have lower rates of survival within the first 30 days post-SAVR, although mid-term and long-term mortality did not differ significantly up to 10 years postoperatively. Pooled estimates of postoperative data indicated no difference in the rates of stroke and postoperative bleeding. Rates of aortic valve reoperation and acute kidney injury favored women.
CONCLUSION
Despite the inferior outcomes for women post-SAVR that have been reported in recent years, the results of this meta-analysis demonstrate comparable results between the sexes with comparable mid- to long-term mortality in data pooled from the literature. Although mortality favored men in the short term, rates of aortic valve reoperation and acute kidney injury favored women. Future investigation into this field should focus on identifying discrepancies in diagnosis and initial surgical management in order to address any potential factors contributing to discrepant short-term outcomes.

Meta-Analysis Review
While TAVI is widely used, optimal medical therapy to reduce the mortality rate after transcatheter aortic valve implantation (TAVI) is still unclear. We performed a systematic review and meta-analysis to evaluate the impact of statins on mortality following TAVI. Present systematic review of the literature was performed using Medline, Embase, Scopus, and Web of Science; all studies reported all-cause mortality in patients who underwent TAVI and received or did not receive statin therapy. Data were analyzed using random-effects models. Seventeen articles (21 380 patients) were included in the meta-analysis. Statin therapy was associated with a reduction of all-cause mortality (Hazard ratio [HR] = .78, 95% Confidence interval [CI] .68-.89, < .001). Moderate between-study heterogeneity was observed (I = 45.2). High-intensity statin therapy was more effective than low or moderate intensity statin therapy in reduction of all-cause mortality (Risk ratio [RR] = .62, 95% CI 0.45-.85, = .003, I = .0). Statin therapy could reduce the mid-term all-cause mortality rate following TAVI. However, all included studies were observational and, therefore, randomized controlled trials are still needed to assess the effect of statin therapy on mortality after TAVI.

Meta-Analysis
OBJECTIVES
While current data show a clear trend towards the use of bioprosthetic valves during aortic valve replacement (AVR), durability of bioprosthetic valves remains the most important concern. We conducted a 1st systematic review of all available evidence that analysed early and mid-term outcomes after AVR using the Inspiris RESILIA™ bioprosthesis.
METHODS
A systematic literature search was performed to identify all relevant studies evaluating early and mid-term outcomes after AVR using the Inspiris RESILIA bioprosthesis and including at least 20 patients with no restriction on the publication date. Subgroup meta-analysis was performed to compare Inspiris RESILIA and PERIMOUNT Magna Ease bioprosthesis and to pool the early postoperative mortality and stroke rates.
RESULTS
A total of 416 studies were identified, of which 15 studies met the eligibility criteria. The studies included a total of 3202 patients with an average follow-up of up to 5.3 years. The average age of patients across the studies was 52.2-75.1 years. Isolated AVR was performed in 39.0-86.4% of patients. In-hospital or 30-day postoperative mortality was 0-2.8%. At the mid-term follow-up, freedom from all-cause mortality was up to 85.4%. Among studies with mid-term follow-up, trace/mild paravalvular leak was detected in 0-3.0%, while major paravalvular leak was found only in up to 2.0% of patients. No statistically significant differences in terms of mortality (P = 0.98, odds ratio 1.02, 95% confidence interval 0.36-2.83) and stroke (P = 0.98, odds ratio 1.01, 95% confidence interval 0.38-2.73) between the Inspiris RESILIA bioprosthesis and PERIMOUNT Magna Ease bioprosthesis were observed in the subgroup meta-analysis.
CONCLUSIONS
Mid-term data on the safety and haemodynamic performance of the novel aortic bioprosthesis are encouraging. Further comparative studies with other bioprostheses and longer follow-up are still required to endorse durability and safety of the novel bioprosthesis.

Meta-Analysis Review
Although surgical ablation has been shown to produce excellent outcomes at follow-up for patients with atrial fibrillation who underwent mitral valve replacement/repair (MVR), this procedure is not commonly performed. Our objective was to conduct a systematic review and meta-analysis to evaluate the outcomes of concomitant surgical ablation during MVR. Three databases were systematically reviewed for randomized clinical trials published by August 2022. The primary outcome was sinus rhythm (SR) at 12 months. Secondary outcomes included SR at discharge and 6 months, all-cause mortality, permanent pacemaker implantation, and stroke and thromboembolic events. A random-effects meta-analysis was performed, calculating odds ratios (ORs) for each outcome. Thirteen studies were included, involving 1,089 patients comparing patients who underwent either isolated MVR ("MVR-only") or concomitant surgical ablation during MVR ("MVR+Ablation"). The odds of SR were significantly higher in the MVR+Ablation group at discharge (OR 9.62, 95% confidence interval [CI] 4.87 to 19.02, I = 55%), at 6-month follow-up (OR 7.21, 95% CI 4.30 to 12.11, I = 34%), and at 1-year follow-up (OR 8.41, 95% CI 5.14 to 13.77, I = 48%). All-cause mortality was not different in the groups, as were stroke and thromboembolic events, whereas the odds of permanent pacemaker implantation were slightly higher in the MVR+Ablation group (OR 1.87, 95% CI 1.11 to 3.17, I = 0%). Concomitant surgical ablation during MVR showed excellent outcomes at short-term follow-up, despite a slightly higher rate of permanent pacemaker implantation. Further studies with longer follow-ups are needed to assess if the SR is maintained over the years.

Meta-Analysis
INTRODUCTION
This study aims to investigate the effect of concomitant tricuspid valve surgery (TVS) during left ventricular assist device (LVAD) implantation due to the controversy over the clinical outcomes of concomitant TVS in patients undergoing LVAD.
METHODS
A systematic literature search was performed in PubMed and EMbase from the inception to 1 August 2023. Studies comparing outcomes in adult patients undergoing concomitant TVS during LVAD implantation (TVS group) and those who did not (no-TVS group) were included. The primary outcomes were right heart failure (RHF), right ventricular assist device (RVAD) implantation, and early mortality. All meta-analyses were performed using random-effects models, and a two-tailed P <0.05 was considered significant.
RESULTS
Twenty-one studies were included, and 16 of them were involved in the meta-analysis, with 660 patients in the TVS group and 1291 in the no-TVS group. Patients in the TVS group suffered from increased risks of RHF [risk ratios (RR)=1.31, 95% CI: 1.01-1.70, P =0.04; I2 =38%, pH =0.13), RVAD implantation (RR=1.56, 95% CI: 1.16-2.11, P =0.003; I2 =0%, pH =0.74), and early mortality (RR=1.61, 95% CI: 1.07-2.42, P =0.02; I2 =0%, pH =0.75). Besides, the increased risk of RHF holds true in patients with moderate to severe tricuspid regurgitation (RR=1.36, 95% CI: 1.04-1.78, P =0.02). TVS was associated with a prolonged cardiopulmonary bypass time. No significant differences in acute kidney injury, reoperation requirement, hospital length of stay, or ICU stay were observed.
CONCLUSIONS
Concomitant TVS failed to show benefits in patients undergoing LVAD, and it was associated with increased risks of RHF, RVAD implantation, and early mortality.

Meta-Analysis Comparative Study Review
Rheumatic Heart Disease (RHD) remains a leading cause of cardiovascular death (CVD) globally. Mitral Valve repair (MVP) and mitral valve replacement (MVR) are the two most commonly and successfully used techniques to treat the disease. MVP is associated with reduced post-operative complications compared to MVR; however, it carries the risk of valvular fibrosis and scarring. Given the lack of recommendations, inconsistent findings, and paucity of pathophysiological evidence at present, we aimed to conduct a meta-analysis and systematically review the available literature to determine the efficacy and safety of MVP compared to MVR in improving clinical outcomes among patients with RHD. A comprehensive literature search was conducted on MEDLINE (PubMed), Cochrane Central and Scopus from inception till September 2023. The primary objective was early mortality defined as any cause-related death occurring 30 days following surgery. Secondary outcomes included long-term survival defined as the time duration between hospital discharge and all-cause death. Infectious endocarditis, thromboembolic events (including stroke, brain infarction, peripheral embolism, valve thrombosis, and transient ischemic attack), and haemorrhagic events (any serious bleeding event that required hospitalisation, resulted in death, resulted in permanent injury, or required blood transfusion) were all considered as post- operative complications. Additionally aggregated Kaplan-Meier curves were reconstructed for long term survival, freedom from reoperation, and freedom from valve-related adverse events by merging the reconstructed individual patient data (IPD) from each individual study. A significant decrease in early mortality with MV repair strategy versus MV replacement [RR 0.63; P = 0.003) irrespective of mechanical or bioprosthetic valves was noted. The results reported significantly higher long-term survival in patients undergoing MVP versus MVR (HR 0.53; P = 0.0009). Reconstructed Kaplan-Meier curves showed that the long term survival rates at 4, 8, and 12 years were 88.6, 82.0, 74.6 %, in the MVR group and 91.7, 86.8, 81.0 %, in the MVP group, respectively. MVP showed statistically significant reduction in early mortality, adverse vascular events, and better long-term survival outcomes compared to the MVR strategy in this analysis.

Meta-Analysis
OBJECTIVES
Adjunctive rifampicin for implant-associated infections is controversial. This study investigated the clinical outcomes of rifampicin combination therapy compared with monotherapy in treating prosthetic joint infection (PJI) or prosthetic valve endocarditis (PVE) due to staphylococci and streptococci.
METHODS
A systematic search was performed from inception to 13 June 2022 in Embase, MEDLINE, Cochrane and Web of Science to investigate the clinical outcomes of rifampicin combination therapy compared with monotherapy in treating staphylococcal and streptococcal PJI or PVE. Randomised controlled trials (RCTs) and observational studies were included in the systematic review and meta-analysis.
RESULTS
Fourteen studies were included. A moderate quality of evidence was found in favour of rifampicin in patients with staphylococcal PJI who underwent a debridement, antibiotics and implant retention (DAIR) procedure [odds ratio = 2.49, 95% confidence interval (CI) 1.93-3.23]. Including the two RCTs only, adding rifampicin to the antibiotic regimen after DAIR was also in favour of rifampicin, but this was not statistically significant (risk ratio = 1.27, 95% CI 0.79-2.04; n = 126). Pooling data for patients with staphylococcal PJI who underwent a two-stage procedure showed that adding rifampicin was not associated with therapeutic success. Limited evidence was found for the use of rifampicin for PVE caused by staphylococci.
CONCLUSIONS
Adding rifampicin in the treatment of staphylococcal PJI treated by DAIR clearly increased the likelihood for therapeutic success. The clinical benefit of adjunctive rifampicin in the treatment of other staphylococci and streptococci implant-associated infections is still unclear.
