Dataset related to article "Long term follow-up after balloon expandable covered stents implantation for management of transcatheter aortic valve replacement related vascular access complications"
<p>This record contains raw data related to article “Long term follow-up after balloon expandable covered stents implantation for management of transcatheter aortic valve replacement related vascular access complications"</p> <p>Abstract</p> <p><strong>Objectives: </strong> To report the experience of a high-volume center with balloon-expandable (BE) stents implantation to manage vascular complications after transcatheter aortic valve replacement (TAVR).</p> <p><strong>Background: </strong> Despite increased operator experience and better devices, vascular complications after TAVR are still a major issue and covered stent implantation is often required.</p> <p><strong>Methods: </strong> We retrospectively collected baseline and procedural data about 78 consecutive patients who underwent BE stent implantation to manage a vascular complication after transfemoral TAVR. Primary endpoints were technical success, incidence of new-onset claudication and need for vascular interventions during long-term follow-up. Secondary endpoints included length of hospitalization, in-hospital and 30-day mortality, and major postoperative complications.</p> <p><strong>Results: </strong> BE stents implantation to manage vascular complications after TAVR was successfully performed in 96.2% of the cases, with bailout surgery required in two cases. One patient suffered in-hospital death. Predischarge Doppler Ultrasound revealed no cases of in-stent occlusion or fracture. At a median follow-up of 429 days (interquartile range, 89-994 days), no cases of symptomatic leg ischemia were reported and only one patient experienced new-onset claudication.</p> <p><strong>Conclusions: </strong> Our experience showed good periprocedural and long-term results of BE covered stent implantation to manage vascular complication after TAVR. Their great radial outward force may guarantee effective hemostasis without necessarily being associated with stent deformation/fracture resulting in restenosis or further interventions. More research is needed to define the role of BE covered stents in this setting.</p>

Dataset related to the article "Computed tomography predictors of structural valve degeneration in patients undergoing transcatheter aortic valve implantation with balloon-expandable prostheses"
<p>This record contains raw data related to the article "Computed tomography predictors of structural valve degeneration in patients undergoing transcatheter aortic valve implantation with balloon-expandable prostheses"</p> <p><strong>Objectives: </strong>Computed tomography (CT) provides excellent anatomy assessment of the aortic annulus (AoA) and is utilized for pre-procedural planning of transcatheter aortic valve implantation (TAVI). We sought to investigate if geometrical characteristics of the AoA determined by CT may represent predictors of structural valve degeneration (SVD) in patients undergoing TAVI with balloon-expandable valves.</p> <p><strong>Methods: </strong>Retrospective study on 124 consecutive patients (mean age:79±7 years; female: 61%) undergoing balloon-expandable TAVI prospectively enrolled in a registry<strong>. </strong>AoA maximum diameter (D<sub>max</sub>), minimum diameter (D<sub>min</sub>), and area were assessed using pre-procedural CT. SVD was identified during follow-up with transthoracic echocardiography documenting structural prosthetic valve abnormalities with or without hemodynamic changes. </p> <p><strong>Results: </strong>The mean follow up was 5.9±1.7 years. SVD was found in 48 out of 124 patients (38%). AoA D<sub>max</sub>, D<sub>min</sub> and area were significantly smaller in patients with SVD compared to patients without SVD (25.6±2.2 mm vs. 27.1±2.8 mm , p=0.012; 20.5±2.1 mm vs. 21.8±2.1 mm ,p=0.001 and 419±77 mm<sup>2 </sup>vs. 467±88 mm<sup>2</sup>,p=0.002, respectively). At univariable analysis, female sex, BSA, 23-mm prosthetic valve size, D<sub>max</sub> <27.1 mm and a D<sub>min</sub> < 19.9 mm were associated with SVD whereas at multivariable analysis, only D<sub>min</sub> <19.9 mm (OR=2.873, 95% CI: 1.191-6.929,p=0.019) and female sex (OR=2.659, 95% CI: 1.095-6.458, p=0.031) were independent predictors of SVD.</p> <p><strong>Conclusions: </strong>Female sex and AoA D<sub>min</sub> < 19.9 mm are associated with SVD in patients undergoing TAVI with balloon expandable valves. When implanting large prostheses in order to avoid paraprosthetic regurgitation, caution should be observed due to the risk of excessive stretching of the AoA D<sub>min,</sub> which may play a role in SVD.</p>

Impact of aortic angle on transcatheter aortic valve implantation outcome with Evolut-R, Portico, and Acurate-NEO
<p>Dataset from Gorla R, De Marco F, Garatti A, Bianchi G, Popolo Rubbio A, Acerbi E, Casenghi M, Spagnolo P, Brambilla N, Testa L, Agnifili ML, Tusa M, Bedogni F. Impact of aortic angle on transcatheter aortic valve implantation outcome with Evolut-R, Portico, and Acurate-NEO. Catheter Cardiovasc Interv. 2021 Jan 1;97(1):E135-E145. doi: 10.1002/ccd.28957. Epub 2020 May 13. PMID: 32400068.</p> <p><strong>Abstract</strong></p> <p><strong>Objectives: </strong>To investigate paravalvular leak (PVL) and devices success rates according to aortic angle (AA) in patients undergoing transcatheter aortic valve implantation (TAVI) with three new-generation self-expanding devices.</p> <p><strong>Background: </strong>The impact of aortic angle (AA) on TAVI device success and PVL rates is controversial.</p> <p><strong>Methods: </strong>This retrospective study included 392 patients submitted to TAVI for severe aortic stenosis with Portico, Evolut-R and Acurate-NEO, and available AA measurements at computed tomography (CT) angiography. AA was calculated from the implantation projection and was defined as the angle between the plane of aortic annulus and an ideal horizontal plane. Aorta was defined horizontal if AA>57° (75th percentile).</p> <p><strong>Results: </strong>In the horizontal group, the rates of moderate/severe PVL was higher in the Evolut-R group (20.8%), which was also characterized by a lower implant compared to that of Acurate-NEO, whereas device success was comparable among the three devices. AA was a significant predictor of moderate/severe PVLs (AUC 0.72, p = .002) only in the Evolut-R population. On multivariate analysis, calcium volume 850HU, bicuspid aortic valve, and implantation depth at the level of left coronary cusp were independent predictors of moderate/severe PVL. On univariate analysis in the horizontal aorta population, implantation depth was confirmed among the most significant predictors of moderate/severe PVL.</p> <p><strong>Conclusions: </strong>Despite comparable device success rates, horizontal aorta represented a technical challenge only in the Evolut-R subgroup, which showed higher rates of moderate/severe PVL than Portico and Acurate-NEO, and was associated with a low implant.</p>

<p>Dataset from Casenghi M, Gorla R, Popolo Rubbio A, De Marco F, Brambilla N, Agnifili M, Testa L, Bedogni F. One-year safety and efficacy profile of transcatheter aortic valve-in-valve implantation with the portico system. Catheter Cardiovasc Interv. 2021 Jul 1;98(1):E145-E152. doi: 10.1002/ccd.29353. Epub 2020 Nov 6. PMID: 33155757.</p> <p>Abstract</p> <p><strong>Objective: </strong>This study sought to investigate the procedural and mid-term outcomes of transcatheter aortic valve implantation for failed surgical bioprostheses (TAVI-ViV) with Portico device.</p> <p><strong>Background: </strong>Limited evidence coming from early experience on Portico system does not allow to fully assess safety and efficacy of this device in this ViV patients.</p> <p><strong>Methods: </strong>From January 2016 up to June 2019, 56 consecutive patients undergoing TAVI-ViV with Portico were prospectively included in our institutional TAVI database.</p> <p><strong>Results: </strong>The prevalent mechanism of failure was stenosis (58.9%); true internal diameter (ID) was <21 mm in 71.4% of cases. Device success rate were 69.6% with 14 (25%) patients showing a residual gradient ≥20 mmHg, 2 (3.6%) a PVL ≥ moderate and 1 (1.8%) required a second THV implantation due to device embolization. At 1-year follow-up 5 patients (8.9%) died whereas moderate SVD was reported in 2 (3.6%). Patients with a post-procedural mean gradient ≥20 mmHg showed a significantly higher rate of CV hospitalization (21.4% vs. 2.4%, p = .02) whereas no differences in procedural and 1-year outcomes were noticed according to true ID diameter or degeneration mode. Chimney stenting (ChT) was performed in 23 (41%) patients without significant differences in procedural and 1-year outcomes compared to non-ChT group.</p> <p><strong>Conclusions: </strong>TAVI-ViV with Portico valve was associated with good procedural and 1-year outcomes, even in patients with features of high procedural and anatomical complexity.</p>
