Project description:BackgroundLimited data are available regarding clinical outcomes of valve-in-valve (ViV) transcatheter aortic valve implantation (TAVI) following the United States Food and Drug Administration approval of ViV TAVI in 2015.AimsThe aim of this study was to evaluate in-hospital, 30-day, and 6-month outcomes of ViV TAVI versus repeat surgical aortic valve replacement (SAVR) in patients with a failed aortic bioprosthetic valve.MethodsThis retrospective cohort study identified patients who underwent ViV TAVI or repeat SAVR utilising the Nationwide Readmission Database from 2016 to 2018. Primary outcomes were all-cause readmission (at 30 days and 6 months) and in-hospital death. Secondary outcomes were in-hospital stroke, pacemaker implantation, 30-day/6-month major adverse cardiac events (MACE), and mortality during readmission. Propensity score-matching (inverse probability of treatment weighting) analyses were implemented.ResultsOut of 6,769 procedures performed, 3,724 (55%) patients underwent ViV TAVI, and 3,045 (45%) underwent repeat SAVR. ViV TAVI was associated with lower in-hospital all-cause mortality (odds ratio [OR] 0.42, 95% confidence interval [CI]: 0.20-0.90, p=0.026) and a higher rate of 30-day (hazard ratio [HR] 1.46, 95% CI: 1.13-1.90, p=0.004) and 6-month all-cause readmission (HR 1.54, 95% CI: 1.14-2.10, p=0.006) compared with repeat SAVR. All secondary outcomes were comparable between the two groups.ConclusionsViV TAVI was associated with lower in-hospital mortality but higher 30-day and 6-month all-cause readmission. However, there was no difference in risk of in-hospital stroke, post-procedure pacemaker implantation, MACE, and mortality during 30-day and 6-month readmission compared with repeat SAVR, suggesting that ViV TAVI can be performed safely in carefully selected patients.

Project description:Background In the absence of randomized controlled trials, reports from nonrandomized studies comparing valve-in-valve implantation (ViV) to redo surgical aortic valve replacement (rAVR) have shown inconsistent results. Methods and Results PubMed/MEDLINE, Google Scholar, and CENTRAL (Cochrane Central Register of Controlled Trials) were searched through December 2021. Meta-Analysis of Observational Studies in Epidemiology guidelines were followed. The protocol was registered at the International Prospective Register of Systematic Reviews. Random effects models were applied. The primary outcomes of interest were short-term and midterm mortality. Secondary outcomes included stroke, myocardial infarction, acute renal failure, and permanent pacemaker implantation, as well as prosthetic aortic valve regurgitation, mean transvalvular gradient, and severe prosthesis-patient mismatch. Of 8881 patients included in 15 studies, 4458 (50.2%) underwent ViV and 4423 (49.8%) rAVR. Short-term mortality was 2.8% in patients undergoing ViV compared with 5.0% in patients undergoing rAVR (risk ratio [RR] 0.55 [95% CI, 0.34-0.91], P=0.02). Midterm mortality did not differ in patients undergoing ViV compared with patients undergoing rAVR (hazard ratio, 1.27 [95% CI, 0.72-2.25]). The rate of acute kidney failure was lower following ViV, (RR, 0.54 [95% CI, 0.33-0.88], P=0.02), whereas prosthetic aortic valve regurgitation (RR, 4.18 [95% CI, 1.88-9.3], P=0.003) as well as severe patient-prothesis mismatch (RR, 3.12 [95% CI, 2.35-4.1], P<0.001) occurred more frequently. The mean transvalvular gradient was higher following ViV (standard mean difference, 0.44 [95% CI, 0.15-0.72], P=0.008). There were no significant differences between groups with respect to stroke (P=0.26), myocardial infarction (P=0.93), or pacemaker implantation (P=0.21). Conclusions Results of this meta-analysis demonstrate better short-term mortality after ViV compared with rAVR. Midterm mortality was similar between groups. Given the likely selection bias in these individual reports, an adequately powered multicenter randomized clinical trial with sufficiently long follow-up in patients with low-to-intermediate surgical risk is warranted.

Project description:A 50-year-old man who required aortic valve replacement (AVR) 3 times for severe paravalvular leakage (PVL) was diagnosed with a recurrence of severe PVL. Since the PVL recurred each time because of prosthetic valve detachment from the annulus, a fourth AVR was performed using a self-expanding sutureless valve. Postoperative echocardiography showed no significant PVL. The patient was discharged without any complications and returned to normal work soon after. In cases such as our patient, sutureless AVR could be a powerful alternative to conventional AVR.

Project description:BackgroundTranscatheter valve-in-valve replacement (ViV-TAVR) has emerged as an alternative to redo-surgical aortic valve replacement (Redo-SAVR) for the treatment of failed surgical aortic bioprostheses. However, the benefit of ViV-TAVR compared with Redo-SAVR remains debated with regard to short-term hemodynamic results and short- and long-term clinical outcomes.ObjectiveThis study aimed to compare short-term hemodynamic performance and long-term clinical outcomes of ViV-TAVR vs. Redo-SAVR in patients treated for surgical aortic bioprosthetic valve failure.MethodsWe retrospectively analyzed the data prospectively collected in 184 patients who underwent Redo-SAVR or ViV-TAVR. Transthoracic echocardiography was performed before and after the procedure and analyzed in an echocardiography core laboratory using the new Valve Academic Research Consortium-3 criteria. An inverse probability of treatment weighting was used to compare the outcomes between both procedures.ResultsViV-TAVR showed lower rate of intended hemodynamic performance (39.2% vs. 67.7%, p < 0.001) at 30 days, which was essentially driven by a higher rate (56.2% vs. 28.8%, p = 0.001) of high residual gradient (mean transvalvular gradient ≥20 mm Hg). Despite a trend for higher 30-day mortality in the Redo-SAVR vs. ViV-TAVR group (8.7% vs. 2.5%, odds ratio [95% CI]: 3.70 [0.77-17.6]; p = 0.10), the long-term mortality was significantly lower (24.2% vs. 50.1% at 8 years; hazard ratio [95% CI]: 0.48 [0.26-0.91]; p = 0.03) in the Redo-SAVR group. After inverse probability of treatment weighting analysis, Redo-SAVR remained significantly associated with reduced long-term mortality compared with ViV-TAVR (hazard ratio [95% CI]: 0.32 [0.22-0.46]; p < 0.001).ConclusionsViV-TAVR was associated with a lower rate of intended hemodynamic performance and numerically lower mortality at 30 days but higher rates of long-term mortality compared with Redo-SAVR.

Project description:ObjectiveWe sought to investigate real-world outcomes of patients with degenerated biological aortic valve prostheses who had undergone valve-in-valve transcatheter aortic valve implantation (ViV-TAVI) or reoperative surgical aortic valve replacement (redo-SAVR) in the Netherlands.MethodsPatients who had undergone ViV-TAVI or redo-SAVR for a degenerated biological aortic valve prosthesis in the Netherlands between January 2014 and December 2018 were eligible for this retrospective study. Patients with a prior homograft, active endocarditis or mechanical aortic valve prosthesis were excluded. Patients were matched using the propensity score. The primary endpoint was a composite of 30-day all-cause mortality and in-hospital postoperative stroke. Secondary endpoints were all-cause mortality at different time points, in-hospital postoperative stroke, pacemaker implantation and redo procedures within one year. Baseline characteristics and outcome data were collected from the Netherlands Heart Registration.ResultsFrom 16 cardiac centres, 653 patients were included in the study (374 ViV-TAVI and 279 redo-SAVR). European System for Cardiac Operative Risk Evaluation I (EuroSCORE I) was higher in ViV-TAVI patients (19.4, interquartile range (IQR) 13.3-27.9 vs 13.8, IQR 8.3-21.9, p < 0.01). After propensity score matching, 165 patients were matched with acceptable covariate balance. In the matched cohorts, the primary endpoint was not significantly different for ViV-TAVI and redo-SAVR patients (odds ratio 1.30, 95% confidence interval 0.57-3.02). Procedural, 30-day and 1‑year all-cause mortality rates, incidence of in-hospital postoperative stroke, pacemaker implantation and redo procedures within one year were also similar between cohorts.ConclusionPatients with degenerated aortic bioprostheses treated with ViV-TAVI or redo-SAVR have similar mortality and morbidity.

Project description:ObjectivesThis analysis evaluated the safety, durability and haemodynamic performance of a stented bovine pericardial valve through 5 years of follow-up in patients with an indication for surgical aortic valve replacement.MethodsKaplan-Meier analysis was used to estimate the incidence of survival and valve-related thromboembolism, major paravalvular leak, endocarditis, structural valve deterioration (SVD) and reintervention. The mean aortic gradient and New York Heart Association (NYHA) functional class were also evaluated.ResultsA total of 1118 patients have received the Avalus valve; 564 have completed the 5-year follow-up. The median follow-up was 4.85 years (4810 patient-years total follow-up). At baseline, the mean age was 70.2 ± 9.0 years; 75.1% of patients were male. The Society of Thoracic Surgeons predicted risk of mortality was 2.0 ± 1.4%. Most patients were in NYHA functional class II (46.8%) or III (40.3%). At the 5-year follow-up, the overall Kaplan-Meier survival rate was 88.1% (85.9-90.0%). The Kaplan-Meier event rates were 5.6% (4.3-7.2%) for thromboembolism, 4.4% (3.2-6.0%) for endocarditis, 0.2% (0.0-0.7%) for a major paravalvular leak and 3.2% (2.3-4.6%) for reintervention. There were no cases of SVD. The mean gradient decreased from 42.1 ± 17.1 mmHg at baseline, to 13.1 ± 4.7 mmHg at discharge and remained stable at 12.5 ± 4.6 mmHg at 5 years. More than 95% of patients were in NYHA functional class I/II 5 years after surgery.ConclusionsThe findings of a high survival rate, excellent safety, no SVD and stable haemodynamic performance and functional status through 5 years of follow-up are encouraging. Additional follow-up is needed to assess the long-term durability of this contemporary surgical bioprosthesis.

Project description:BackgroundRapid-deployment aortic valve replacement (RDAVR) is an alternative to conventional AVR (cAVR) for aortic stenosis. Benefits include a reduction in operative times, facilitation of minimal access surgery and superior haemodynamics compared to conventional valves. However, further evidence is required to inform guidelines, preferably in the form of propensity-matched studies that include mid-term follow-up data.MethodsThis was a single-centre, retrospective, propensity-matched cohort study comparing the Perceval and conventional Perimount Magna Ease valve for short- and mid-term clinical parameters and size-matched mid-term echocardiographic parameters (n = 102 in both groups) from 2014 to 2020. Data were extracted from a nationally managed dataset.ResultsThere were no demographic differences between the matched groups. The Perceval group had shorter cross-clamp time (Perceval 62 [49-81] minutes; Perimount 79 [63-102] minutes, P < 0.001), shorter bypass time (Perceval 89 [74-114] minutes; Perimount 104 [84-137] minutes, P < 0.001), and more frequent minimally-invasive approaches (Perceval 28%; Perimount 5%, P < 0.001). Size-matched haemodynamics showed initially higher gradients in the Perceval group, but haemodynamics equalised at 12 + months. The Perceval group had a more favourable % change in the left ventricular posterior wall dimension at 2 + years (Perceval - 4.8 ± 18; Perimount 17 ± 2).ConclusionsThe Perceval facilitated shorter operations, which may benefit intermediate-high-risk, elderly patients with comorbidities requiring concomitant procedures. It also facilitated minimally invasive surgery. Size-matched haemodynamic performance was similar at mid-term follow-up, with the Perceval possibly better facilitating regression of left ventricular hypertrophy.
