Project description:BACKGROUND:Three-dimensional (3D) models have the unique ability to replicate individualized cardiac anatomy and may therefore provide clinical benefit. Transcatheter aortic valve implantation (TAVI) currently relies on preoperative imaging for accurate valve sizing, type of valve used, and avoidance of complications. Three-dimensional (3D) modelling may provide benefit for optimal preoperative TAVI planning. The goal of this study is to assess the utility of 3D modelling in the prediction of paravalvular leak (PVL) post TAVI. METHODS:Retrospective analysis of five patients who underwent TAVI at our center. Pre-operative cardiac gated CT images were utilized to create a 3D printed model with true size aortic root dimensions, including the coronary artery ostium location and left ventricular outflow tract. Deployment of the corresponding model and size TAVI valve into the created 3D model at a similar depth of implantation via fluoroscopy was performed for each patient. Degree of PVL was assessed using a closed system with water infusion under pressure over a duration of 5 s. Correlation was made between the volume obtained in the closed loop model during the pressurized period and the degree of PVL reported on the patients post TAVI placement on transthoracic echocardiogram. RESULTS:One female, and four males (age in years ranged from 68 to 87) underwent successful TAVI (0% 30-day mortality). PVL on post procedure TTE ranged from none to trivial. Successful deployment of TAVI valves inside the 3D model occurred in all cases. The average volume of water collected on three trials over 5 s ranged between 19.1-24.1?ml A multivariate linear regression showed significant association between the degree of PVL reported on post-operative transthoracic echocardiogram and the amount of volume detected in the 3D model (difference: -3.9657, 95% CI: (-?4.6761,-3.2554), p?<?0.001). CONCLUSIONS:Our experiments show that replicated 3D models have potential clinical utilization in predicting PVL in the TAVI population. Future research into the role of 3D modelling in the field of TAVI should continue to be explored.

Project description:To evaluate the prognostic relevance of aortic annulus (AA) and left ventricular outflow tract (LVOT) Fractal dimension (FD). FD is a mathematical concept that describes geometric complexity of a structure and has been shown to predict adverse outcomes in several contexts. Computed tomography (CT) scans from the SOLVE-TAVI trial, which, in a 2 × 2 factorial design, randomized 447 patients to TAVI with the balloon-expandable Edwards Sapien 3 or the self-expanding Medtronic Evolut R, and conscious sedation or general anesthesia, were analyzed semi-automatically with a custom-built software to determine border of AA and LVOT. FD was measured by box counting using grid calibers between 0.8 and 6.75 mm and was compared between patients with none/trivial and mild/moderate paravalvular regurgitation (PVR). Overall, 122 patients had CT scans sufficient for semi-automatic PVR in 30-day echocardiography. PVR was none in 65(53.3%) patients, trace in 9(7.4%), mild in 46(37.7%), moderate in 2(1.6%) and severe in 0 patients. FD determined in diastolic images was significantly higher in patients with mild/moderate PVR (1.0558 ± 0.0289 vs. 1.0401 ± 0.0284, p = 0.017). Annulus eccentricity was the only conventional measure of AA and LVOT geometry significantly correlated to FD (R = 0.337, p < 0.01). Area under the curve (AUC) of diastolic annular FD for prediction of mild/moderate PVR in ROC analysis was 0.661 (0.542-0.779, p = 0.014). FD shows promise in prediction of PVR after TAVI. Further evaluation using larger patient numbers and refined algorithms to better understand its predictive performance is warranted.Trial Registration: www.clinicaltrials.gov , identifier: NCT02737150, date of registration: 13.04.2016.

Project description:BackgroundRecently, the Valve Academic Research Consortium (VARC)-3 criteria redefined bioprosthetic valve dysfunction (BVD) after transcatheter aortic valve implantation (TAVI). However, the rate of BVD is scarcely reported in current practice.AimsWe aimed to evaluate the rate and predictors of BVD after TAVI based on the VARC-3 criteria.MethodsWe retrospectively analysed patients who had undergone TAVI using single-centre data. BVD was reported as exposure-adjusted event rates with a patient-year unit (per 100 patient-years). Predictors of BVD after TAVI were analysed using Fine-Gray competing risk regression to account for the competing risk of death.ResultsAmong 514 patients, the rate of BVD was 7.5 events per 100 patient-years (n=74) at a median follow-up of 1.9 years. The main cause of BVD was moderate or severe prosthesis-patient mismatch (PPM; n=59). The Fine-Gray model demonstrated that predilatation was associated with a lower rate of BVD, mainly moderate or severe PPM (adjusted subdistribution hazard ratio [sub-HR] 0.42, 95% confidence interval [CI]: 0.21-0.88). In a subgroup analysis, the patients with a small aortic annulus (area <400 mm2 or perimeter <72 mm) tended to benefit from predilatation (p for interaction=0.03). The same regression model also demonstrated that a small balloon-expandable valve (BEV; ≤23 mm) was associated with a higher rate of BVD (adjusted sub-HR 2.46, 95% CI: 1.38-4.38).ConclusionsOur study suggested that the rate of BVD in patients undergoing TAVI is relatively low at midterm follow-up. Predilatation, particularly in small annuli and small BEV might have an impact on BVD, mainly caused by moderate or severe PPM, after TAVI.

Project description:As the use of surgically implanted sutureless aortic valves has increased over the past decade, we expect to encounter their failure increasingly in coming years. We describe a case of Perceval aortic valve failure with stent infolding and severe stenosis. This condition was treated with valve-in-valve transcatheter aortic valve implantation and complicated by aortic annular rupture at the site of infolding. This case is important because it outlines the limited experience with valve-in-valve transcatheter aortic valve implantation to treat failed sutureless valves and identifies sutureless valve infolding as a potential risk for annular rupture.

Project description:BackgroundMajor uncertainties remain regarding disease activity within the retained native aortic valve, and regarding bioprosthetic valve durability, after transcatheter aortic valve implantation (TAVI). We aimed to assess native aortic valve disease activity and bioprosthetic valve durability in patients with TAVI in comparison with subjects with bioprosthetic surgical aortic valve replacement (SAVR).MethodsIn a multicenter cross-sectional observational cohort study, patients with TAVI or bioprosthetic SAVR underwent baseline echocardiography, computed tomography angiography, and 18F-sodium fluoride (18F-NaF) positron emission tomography. Participants (n=47) were imaged once with 18F-NaF positron emission tomography/computed tomography either at 1 month (n=9, 19%), 2 years (n=22, 47%), or 5 years (16, 34%) after valve implantation. Patients subsequently underwent serial echocardiography to assess for changes in valve hemodynamic performance (change in peak aortic velocity) and evidence of structural valve dysfunction. Comparisons were made with matched patients with bioprosthetic SAVR (n=51) who had undergone the same imaging protocol.ResultsIn patients with TAVI, native aortic valves demonstrated 18F-NaF uptake around the outside of the bioprostheses that showed a modest correlation with the time from TAVI (r=0.36, P=0.023). 18F-NaF uptake in the bioprosthetic leaflets was comparable between the SAVR and TAVI groups (target-to-background ratio, 1.3 [1.2-1.7] versus 1.3 [1.2-1.5], respectively; P=0.27). The frequencies of imaging evidence of bioprosthetic valve degeneration at baseline were similar on echocardiography (6% versus 8%, respectively; P=0.78), computed tomography (15% versus 14%, respectively; P=0.87), and positron emission tomography (15% versus 29%, respectively; P=0.09). Baseline 18F-NaF uptake was associated with a subsequent change in peak aortic velocity for both TAVI (r=0.7, P<0.001) and SAVR (r=0.7, P<0.001). On multivariable analysis, 18F-NaF uptake was the only predictor of peak velocity progression (P<0.001).ConclusionsIn patients with TAVI, native aortic valves demonstrate evidence of ongoing active disease. Across imaging modalities, TAVI degeneration is of similar magnitude to bioprosthetic SAVR, suggesting comparable midterm durability.

Project description:This report describes a successful transcatheter aortic valve replacement in an older patient with severe aortic stenosis, mitral paravalvular leak, and associated hemolytic anemia. Transcatheter aortic valve replacement is worth considering as a first-line procedure in this high-risk patient because of its beneficial impact on reducing shear forces at the mitral valve.

Project description:Transcatheter mitral valve replacement (TMVR) has emerged as a feasible alternative to surgical reoperation in failed bioprostheses and rings. Residual mitral regurgitation following TMVR can present as a valve-in-valve paravalvular leak (PVL) and is associated with increased morbidity and mortality. Current therapies for valve-in-valve PVL are limited. We present a case of a symptomatic patient with severe valve-in-valve PVL after TMVR for a previous surgical bioprosthesis leak, who then underwent a second TMVR as a valve-in-valve-in-valve implantation with a 29 mm Edwards® SAPIEN 3 valve via transseptal approach using three-dimensional (3D) echocardiography. This unique case highlights the complexity of this clinical entity and recognizes 3D transesophageal echocardiography as a valuable tool to guide valve-in-valve PVL closures.

Project description:BackgroundMild paravalvular regurgitation (PVR) remains a frequent and underappreciated adverse event after transcatheter aortic valve implantation (TAVI) despite remarkable progress in device technology and implantation technique.AimsThis study sought to investigate the impact of mild PVR after TAVI on five-year clinical outcomes.MethodsIn a prospective TAVI registry, PVR prior to discharge was retrospectively assessed in an echocardiographic core laboratory. Patients with ≥moderate PVR were excluded. Mild PVR was categorised into mild and mild-to-moderate PVR using a recently proposed unifying 5-class grading scheme.ResultsA total of 1,128 patients undergoing TAVI between 2007 and 2015 were enrolled. Of these, 560 patients had mild PVR, including 433 with mild (5-class) PVR and 127 with mild-to-moderate PVR. Patients with mild PVR were older (83 years vs 82 years, p=0.013) and had a higher surgical risk compared to patients with none/trace PVR (STS-PROM: 6.49±4.68 vs 5.41±3.48, p<0.001). At five years, patients with mild PVR had a higher risk of mortality than those with none/trace PVR (54.6% vs 43.8%; HRadjusted 1.26, 95% CI: 1.06-1.50). When applying the 5-class grading scheme, only mild-to-moderate PVR was associated with an increased risk of mortality at five years (mild PVR: HRadjusted 1.19, 95% CI: 0.99-1.43, mild-to-moderate PVR: HRadjusted 1.56, 95% CI: 1.20-2.02). The effect of mild PVR on five-year mortality was consistent across major subgroups.ConclusionsMild PVR was associated with an increased risk of mortality at five years after TAVI. The detrimental effect was primarily driven by mild-to-moderate PVR using the 5-class grading scheme.Clinical trial registrationhttps://www.Clinicaltrialsgov. NCT01368250.
