Early and mid-term outcomes after transcatheter aortic valve implantation (TAVI) in Ireland.

ABSTRACT: TAVI is a percutaneous approach to aortic valve replacement in high surgical risk patients deemed inoperable.To evaluate the early and mid-term outcomes for an Irish TAVI cohort over a six-year period at St James's Hospital and Blackrock Clinic, Dublin, Ireland.In total 147 patients, 56% male with an average age of 82 underwent TAVI between December 2008 and December 2014. Thirty day, one year and two year survival was 90.5%, 83% and 71% respectively. Major vascular complications and renal failure were the biggest predictors of mortality at 30 days (p = 0.02). We observed a pacing rate of 13.5%, the majority in patients who had Medtronic Corevalve implants (p < 0.05). With increasing procedural experience there was a reduction in length of stay from 10 days to 7.5 days.This review, the first of its kind in Ireland showed favorable rates of 30 day and one year and two year survival post TAVI with procedural success and complication rates similar to international registry data.

Early and Mid-Term Outcomes of Transcatheter Aortic Valve Implantation versus Surgical Aortic Valve Replacement: Updated Systematic Review and Meta-Analysis.

Project description:(1) Background: The use of transcatheter aortic valve implantation (TAVI) for the treatment of severe symptomatic aortic stenosis is expanding significantly. We aimed to perform a meta-analysis comparing the safety and efficacy of TAVI versus surgical aortic valve replacement (SAVR) during the early and mid-term follow-up period. (2) Methods: We conducted a meta-analysis of randomized controlled trials (RCTs) comparing 1- to 2-year outcomes between TAVI and SAVR. The study protocol was preregistered in PROSPERO and the results were reported according to PRISMA guidelines. (3) Results: The pooled analysis included data from eight RCTs totaling 8780 patients. TAVI was associated with a lower risk of all-cause mortality or disabling stroke (OR 0.87, 95%CI 0.77-0.99), significant bleeding (OR 0.38, 95%CI 0.25-0.59), acute kidney injury (AKI; OR 0.53, 95%CI 0.40-0.69) and atrial fibrillation (OR 0.28, 95%CI 0.19-0.43). SAVR was associated with a lower risk of major vascular complication (MVC; OR 1.99, 95%CI 1.29-3.07) as well as permanent pacemaker implantation (PPI; OR 2.28, 95%CI 1.45-3.57). (3) Conclusions: TAVI compared with SAVR during early and mid-term follow-up was associated with a lower risk of all-cause mortality or disabling stroke, significant bleeding, AKI and atrial fibrillation; however, it was associated with a higher risk of MVC and PPI.

Prevalence, Predictors, and Mid-Term Outcomes of Non-Home Discharge After Transcatheter Aortic Valve Implantation.

Project description:Background: Transcatheter aortic valve implantation (TAVI) has been widely used as a valued alternative to surgical aortic valve replacement. In cardiovascular surgeries, discharge disposition has been widely investigated. We examined the prevalence and predictors of non-home discharge after TAVI, and the prognosis based on discharge destination. Methods and Results: We retrospectively analyzed 732 consecutive patients undergoing TAVI, and divided them into 2 groups: the home group (discharged directly home; n=678 [92.6%]) and the non-home group (n=54 [7.4%]). From baseline and procedural characteristics, peripheral artery disease (PAD; odds ratio [OR] 2.73; 95% confidence interval [CI] 1.25-5.97; P=0.012), previous stroke (OR 2.57; 95% CI 1.03-6.45; P=0.045), albumin level (OR 0.16 per 1-g/dL increase; 95% CI 0.07-0.39; P<0.001), and procedural stroke (OR 31.6; 95% CI 10.9-91.7; P<0.001) were independently associated with non-home discharge. In Kaplan-Meier analysis, the non-home group had worse survival than the home group (log-rank, P=0.001). In multivariate analysis, male sex, atrial fibrillation or atrial flutter, and low albumin concentrations were associated with all-cause mortality, but non-home discharge was not (P=0.18). Conclusions: Non-home discharge was recorded for 7.4% of patients undergoing TAVI, and was associated with PAD, nutritional status, and previous and procedural stroke. Non-home discharge reflects worse baseline characteristics, and may be a marker of mid-term outcome after TAVI.

Outcomes of Redo Transcatheter Aortic Valve Implantation for Structural Valve Degeneration of Transcatheter Aortic Valve.

Project description:Background: The outcome of redo transcatheter aortic valve (TAV) implantation (TAVI) is unknown for TAV structural valve degeneration (SVD). This paper reports the initial results of redo TAVI for TAV-SVD in Japanese patients. Methods and Results: Of 630 consecutive patients, 6 (1.0%) underwent redo TAVI for TAV-SVD (689-1,932 days after the first TAVI). The first TAV were 23-mm balloon-expandable valves (BEV, n=5) and a 26-mm self-expandable valve (SEV, n=1). All patients underwent multidetector computed tomography (MDCT) before redo TAVI, which showed first-TAV under-expansion (range, 19.1-21.0 mm) compared with the label size. Two BEV and 4 SEV were successfully implanted as second TAV, without moderate/severe regurgitation or 30-day mortality. One of 2 patients with a BEV-inside-BEV implantation had a high transvalvular mean pressure gradient post-procedurally (34 mmHg) and required surgical valve replacement 248 days after the redo TAVI. This, however, was unnoted in patients with SEV implantation during redo TAVI. Planned coronary artery bypass grafting was concomitantly performed in 1 patient with a small sino-tubular junction and SEV-inside-SEV implantation because of the risk of coronary malperfusion caused by the first TAV leaflets. Five of the 6 patients survived during the follow-up period (range, 285-1,503 days). Conclusions: Redo TAVI for TAV-SVD appears safe and feasible, while specific strategies based on MDCT and device selection seem important for better outcomes.

Long-term outcomes following transcatheter aortic valve implantation with the Portico self-expanding valve.

Project description:AimTranscatheter aortic valve implantation (TAVI) is a mainstay in the management of severe aortic valve stenosis in elderly patients, but there is uncertainty on their long-term effectiveness. We aimed to assess the long-term outcome of patients undergoing TAVI with the Portico valve.MethodsWe retrospectively collected the data on patients in whom TAVI with Portico was attempted from 7 high-volume centres. Only patients theoretically eligible for 3 or more years of follow-up were included. Clinical outcomes, including death, stroke, myocardial infarction, reintervention for valve degeneration and hemodynamic valve performance were systematically assessed.ResultsA total of 803 patients were included, with 504 (62.8%) women, mean age of 82 years, median EuroSCORE II of 3.1%, and 386 (48.1%) subjects at low/moderate risk. The median follow-up was 3.0 years (3.0; 4.0). The composite of death, stroke, myocardial infarction, and reintervention for valve degeneration occurred in 37.5% (95% confidence interval: 34.1-40.9%), with all-cause death in 35.1% (31.8-38.4%), stroke in 3.4% (1.3-3.4%), myocardial infarction in 1.0% (0.3-1.5%), and reintervention for valve degeneration in 1.1% (0.6-2.1%). The mean aortic valve gradient at follow-up was 8.1 ± 4.6 mmHg, and at least moderate aortic regurgitation was present in 9.1% (6.7-12.3%). Independent predictors of major adverse events or death were: peripheral artery disease, chronic obstructive pulmonary disease, estimated glomerular filtration rate, atrial fibrillation, prior pacemaker implantation, EuroSCORE II, and reduced left ventricular ejection fraction (all p < 0.05).ConclusionsPortico use is associated with favorable long-term clinical outcomes. Clinical outcomes were largely impacted by baseline risk factors and surgical risk.

Influence of coronary artery disease and percutaneous coronary intervention on mid-term outcomes in patients with aortic valve stenosis treated with transcatheter aortic valve implantation.

Project description:BackgroundA high frequency of coronary artery disease (CAD) is reported in patients with severe aortic valve stenosis (AS) who undergo transcatheter aortic valve implantation (TAVI). However, the optimal management of CAD in these patients remains unknown.HypothesisWe hypothesis that AS patients with TAVI complicated by CAD have poor prognosis. His study evaluates the prognoses of patients with CAD and severe AS after TAVI.MethodsWe divided 186 patients with severe AS undergoing TAVI into three groups: those with CAD involving the left main coronary (LM) or proximal left anterior descending artery (LAD) lesion (the CAD[LADp] group), those with CAD not involving the LM or a LAD proximal lesion (the CAD[non-LADp] group), and those without CAD (Non-CAD group). Clinical outcomes were compared among the three groups.ResultsThe CAD[LADp] group showed a higher incidence of major adverse cardiovascular and cerebrovascular events (MACCEs) and all-cause mortality than the other two groups (log-rank p = .001 and p = .008, respectively). Even after adjustment for STS score and percutaneous coronary intervention (PCI) before TAVI, CAD[LADp] remained associated with MACCE and all-cause mortality. However, PCI for an LM or LAD proximal lesion pre-TAVI did not reduce the risk of these outcomes.ConclusionsCAD with an LM or LAD proximal lesion is a strong independent predictor of mid-term MACCEs and all-cause mortality in patients with severe AS treated with TAVI. PCI before TAVI did not influence the outcomes.

Validation of transcatheter aortic valve implantation risk scores in relation to early and mid-term survival: a single-centre study.

Project description:ObjectivesThe aim of this study was to validate recently proposed risk scores for the prediction of mortality up to 1 year after transcatheter aortic valve implantation (TAVI), using a self-expandable valve (CoreValve).MethodsIn this single-centre study, 225 consecutive patients with severe symptomatic aortic valve stenosis, who underwent TAVI between December 2007 and January 2015, were included. Conventional surgical risk scores (logistic EuroSCORE, EuroSCORE II and STS score) were calculated as well as newly proposed TAVI risk scores (TAVI2-SCORe, STT Score and OBSERVANT score). Medium-term survival of the patients was assessed up to 1 year after TAVI.ResultsThe median age was 82 (77-86) years and 45.3% were male. Patients were categorized into 'non-high risk' or 'high risk' according to logistic EuroSCORE >20%, EuroSCORE II >8%, STS score >10%, TAVI2-SCORe >2, STT score >12% and OBSERVANT score >6. Thirty-day and 1-year survival rates were significantly different between 'non-high-risk' and 'high-risk' patients according to the STS score (1 year: low: 84.4% vs high: 67.0%, P = 0.010) and according to OBSERVANT score (1 year: low: 85.2% vs high: 68.4%, P = 0.005). In contrast, TAVI2-SCORe and STT score did not discriminate 'non-high-risk' and 'high-risk' patients. This was confirmed by Cox regression analysis [STS score >10%: hazard ratio: 2.484 (1.206-5.115), P = 0.014; OBSERVANT score >6: hazard ratio: 2.532 (1.295-4.952), P = 0.007].ConclusionsIn this single-centre study, OBSERVANT and STS score most accurately predicted early and mid-term survival in patients undergoing TAVI, using a self-expandable valve (CoreValve).

Aortic valve anatomy and outcomes after transcatheter aortic valve implantation in bicuspid aortic valves.

Project description:This original clinical research study id focused on description of baseline anatomy and outcomes after transcatheter aortic valve implantation (TAVI) in patients presenting with severe aortic stenosis (AS) and bicuspid aortic valve (BAV). We compared this BAV population with a population of patients with AS and tricuspid aortic valves after a propensity score matching developed by a multivariate logistic regression according to a non-parsimonious approach. Baseline anatomical characteristics were obtained by transthoracic echocardiography (TTE) and multi-sliced computed tomography (MSCT) and compared by chi-square and t-student tests. Outcomes were evaluated by correct fisher test at in hospital and 30 days follow-up. We found that BAV patients presents more complicated baseline anatomy as compared to patients with tricuspid valves. These anatomical features lead to higher procedural complications as the need for a second device implantation. However this does not translate into increase in mortality rate at 30 days follow-up but rather correlate to a lower device success rate.

Early safety and mid-term clinical outcomes of technology transfer of transcatheter aortic valve implantation in patients with severe aortic valve stenosis in Vietnam: a single-center experience of 90 patients.

Project description:BackgroundThis study investigated the early safety and mid-term outcomes of stepwise implementation of transcatheter aortic valve implantation (TAVI) in Vietnamese patients with severe aortic stenosis (AS) at a single center, following the process of technical transfer.MethodsFrom 2017 to 2022, 90 patients with symptomatic severe AS underwent TAVI at a tertiary hospital in Vietnam. The first 30 cases received support for technology transfer from international proctors. One-year outcomes were evaluated using the Valve Academic Research Consortium-2 (VARC-2) criteria.FindingsForty patients (45.5%) had bicuspid aortic valve (BAV). The Medtronic Evolut R/Pro self-expanding valve system was used in 98.9% of all cases, with a 29-mm valve being the most common. Device success was achieved in 95.6% of cases, whereas one procedural death occurred. At one year, four deaths (5.3%) occurred and all were in the BAV group. Other complications included stroke (2.8%), hospital readmission due to the valve or worsening heart failure (2.8%), permanent pacemaker implantation (9.9%), and moderate paravalvular leak (3.0%). The left ventricular ejection fraction and mean transvalvular gradient significantly improved after TAVI. There were no significant differences in procedural success and mortality when the proctor support period and the subsequent solo operator period were compared.InterpretationTAVI procedure is safe for treating severe AS in Vietnamese patients, despite the high prevalence of BAV. The procedural complication rate was low, with promising outcomes at one year. These results also highlight the effectiveness of the TAVI technical transfer model in Vietnam.FundingNo funding was provided for this study.

Annular Rupture During Transcatheter Aortic Valve Implantation: Predictors, Management and Outcomes.

Project description:Transcatheter aortic valve implantation (TAVI) is the treatment of choice in patients with symptomatic severe aortic stenosis who are either inoperable or at high risk for conventional surgical aortic valve replacement. Recent data have also shown favourable outcomes in patients deemed to be at intermediate operative risk, which expands the application of this novel technology. Despite its success, TAVI has been associated with rare life-threatening complications. Of these, aortic annular rupture is considered to be the most devastating. Advances in pre-procedural screening and patient selection have reduced the incidence of annular rupture. When this complication occurs, early recognition and prompt management are essential. This article is intended to provide a comprehensive review of the predictors, management and clinical outcomes of aortic annular rupture.

Cognitive Outcomes following Transcatheter Aortic Valve Implantation: A Systematic Review.

Project description:Severe aortic stenosis is the most common valvular heart disease in the elderly in the Western world and contributes to a large proportion of all deaths over the age of 70. Severe aortic stenosis is conventionally treated with surgical aortic valve replacement; however, the less invasive transcatheter aortic valve implantation (TAVI) is suggested for those at high surgical risk. While TAVI has been associated with improved survival and favourable outcomes, there is a higher incidence of cerebral microembolisms in TAVI patients. This finding is of concern given mechanistic links with cognitive decline, a symptom highly prevalent in those with cardiovascular disease. This paper reviews the literature assessing the possible link between TAVI and cognitive changes. Studies to date have shown that global cognition improves or remains unchanged over 3 months following TAVI while individual cognitive domains remain preserved over time. However, the association between TAVI and cognition remains unclear due to methodological limitations. Furthermore, while these studies have largely focused on memory, cognitive impairment in this population may be predominantly of vascular origin. Therefore, cognitive assessment focusing on domains important in vascular cognitive impairment, such as executive dysfunction, may be more helpful in elucidating the association between TAVI and cognition in the long term.
