Abstract Background Differences in mean gradients after Transcatheter valve replacement (TAVR) vary depending on the valve type and the modality used to measure the gradients. Currently there is a paucity of data on the relationship between invasive and doppler derived gradients after TAVR. Purpose We sort to assess the difference in doppler, and catheter derived aortic valve gradients after TAVR Methods This is a single center retrospective study using consecutive patients who presented for TAVR on account of native aortic valve stenosis at our institution from May 2012 till December 2020. Patients with both intraoperative invasive and postoperative doppler derived pressure gradients were included in the analysis. Student T-test were used to compare mean gradients. Pearson's correlation test was used to examine the correlation between measured gradients. Results A total of 587 patients were included in our study. Fifty one percent were male and 462 (78.7%) underwent TAVR with a balloon expandable valve. In the entire cohort the mean gradient measured invasively was significantly lower than those measured by echo doppler (4.48±3.25 vs. 5.57±3.11, P<0.001). There, however, was a positive correlation between invasive and doppler measured gradients (figure 1). In those who received balloon expandable valves, the invasive gradient was 4.39±3.30 and the doppler derived gradient was 5.47±3.04 (P<0.001), while in those self-expanding valves, the invasive gradient was 4.81±3.04 and doppler derived gradient was 5.94±3.36 (P<0.001). Conclusion Post TAVR gradients were all significantly lower when measured invasively as compared to those measured using doppler. Self-expanding valves overall had higher residual gradients. Further studies are needed to assess the correlations between invasively measured gradients and clinical outcomes post TAVR. FUNDunding Acknowledgement Type of funding sources: None.

Background: Paravalvular regurgitation (PVR) after transcatheter aortic valve replacement is associated with adverse clinical outcomes. The SAPIEN 3 Ultra (Ultra) is a new generation balloon-expandable transcatheter heart valve with a modified external skirt that is designed to reduce PVR, but reports of clinical and echocardiographic outcomes are limited. The aim of this study was to compare short-term outcomes of patients undergoing transcatheter aortic valve replacement with the Ultra and the original SAPIEN 3 (S3) transcatheter heart valve in a large national registry. Methods: Data from The Society of Thoracic Surgeons/American College of Cardiology Transcatheter Valve Therapy Registry was used to compare patients who underwent elective, transfemoral transcatheter aortic valve replacement with the Ultra or S3 transcatheter heart valve. Clinical and echocardiographic outcomes were analyzed in a propensity-matched cohort at discharge and 30 days. Results: Patients who underwent transcatheter aortic valve replacement with Ultra (N=1324) from January 2019 to February 2020 were propensity score–matched with patients treated with S3 (N=32 982) during the same period, resulting in 1324 matched pairs. There was no difference in the rate of device success between patients treated with Ultra and S3 (97.1% versus 98.0%, P =0.11). At hospital discharge, PVR was significantly reduced with Ultra compared with S3, with mild PVR in 9.0% versus 13.9% and moderate or greater PVR in 0.1% versus 0.4% (overall P <0.01). At 30 days, there were no differences between Ultra and S3 recipients in the rates of all-cause mortality or stroke (1.8% versus 2.8%, P =0.10), major vascular complications (1.1% versus 1.0%, P =0.84), or permanent pacemaker implantation (6.4% versus 6.2%, P =0.81). Conclusions: In this propensity-matched analysis from the Transcatheter Valve Therapy Registry, the Ultra transcatheter heart valve was associated with similar procedural and 30-day clinical outcomes, but reduced incidence of PVR, compared with S3. The clinical benefit of less PVR should be evaluated in longer-term studies.

Objectives: Transcatheter aortic valve-in-valve implantation (ViV) is an innovative treatment for failed tissue valves (TV) in patients at high surgical risk. However, direct comparative data with standard repeat surgical aortic valve replacement (RE-SAVR) is scarce. We aimed to compare outcomes after ViV to conventional RE-SAVR in two European centers with established interventional programs. Methods: Retrospectively we explored in-hospital databases for patients ≥60 years, treated for degenerated TV. Patients with endocarditis and combined procedures were excluded. Primary endpoints were adjudicated according to VARC-2 criteria. Results: Between 2002 and 2015, 130 patients were treated for isolated failure of aortic TV’s (ViV: n=71, RE-SAVR: n=59). In ViV, Edwards Sapien valve (ESV) was most frequently used (n=36) but implanted into larger TV’s (CoreValve TV size: 22.2±1.3mm vs. ESV TV size: 24.1±2.0mm, p<0.01). Both age and logistic EuroSCORE I were higher in ViV compared to RE-SAVR (78.6±7.5 vs. 72.9±6.5 ys, p<0.01; 25.1±18.9 vs. 16.8±9.4%, p<0.01). Thirty-day mortality was not significantly different with 4.2% (3/71) after ViV vs. 5.1% (3/59) post RE-SAVR (p=1.0). Device success was achieved in 54.9% (n=39) in ViV and all RE-SAVR patients (p<0.01). Perioperative stroke was not observed after ViV and in 2 patients after RE-SAVR (3.4%, p=0.2). Intensive-care stay was longer after RE-SAVR (3.4±2.9d vs. 1.9±1.8d, p<0.01). Following ViV, 22.5% (n=16) of patients had mild aortic regurgitation, vs. 11.3% (n=8; p=0.25) after RE-SAVR. Mean transvalvular pressure gradients at discharge were higher post ViV (19.3±7.3 vs.12.2±5.6mmHg, p<0.01). Rate of permanent pacemaker implantation was lower after ViV (9.9% vs. 27.1%, p<0.01). Survival at 90- and 180-days was 93.8% and 91.8% vs. 94.4% and 94.4% after ViV and RE-SAVR respectively (p=0.87). Conclusion: Despite a higher risk profile, early mortality was not different between the two treatment arms. Although ViV resulted in elevated postoperative transvalvular pressure gradients and therefore a lower rate of device success, mortality after 180-days was similar to RE-SAVR. At present, both techniques serve as complementary approaches and allow individualized patient care.

Objective Despite advancements in transcatheter aortic valve replacement (TAVR) technology, alternate access strategies are still required when transfemoral access is unsuitable. In these often anatomically complex group of patients, we sought to evaluate the safety and feasibility of suprasternal transinnominate (TI) artery access for TAVR. Methods At our institution, 652 patients underwent TAVR from November 2011 through February 2020. Of these, 23 patients underwent TI TAVR via a 5-cm suprasternal incision without special instrumentation. Outcomes of interest were technical considerations, postoperative complications, and perioperative recovery in relation to established access strategies. Results The mean Society of Thoracic Surgeons risk score was 8.6 ± 4.2 and the average age was 75 ± 8. All patients underwent TI TAVR using a self-expanding (12), or balloon-expandable (11) transcatheter heart valve. Average postoperative stay was 2 ± 0.7 days (range 2 to 4) with most 20/23 (87%) being discharged to home. There was no 30-day mortality or readmission. There was 1 access-site complication and 1 cerebrovascular accident within 30 days, both intraoperative, with excellent recovery. All patients had either trivial (19) or mild (4) aortic regurgitation on 30-day echocardiography. Conclusions TAVR via suprasternal TI access is feasible, safe, provides satisfactory perioperative recovery and adds to the options when patients require alternate access. Further data would be optimal to validate this single-center experience.

Abstract Background Transcatheter aortic valve replacement (TAVR) reverses LV remodeling and improves overall cardiac function, but data regarding its effect on left atrial (LA) function is scarce. Our aim was to evaluate the short-term effect of TAVR on LA myocardial deformation parameters and the relationship between the improvement of LA function and baseline echocardiographic parameters. Methods Fourty-eight consecutive pts (75 ± 6 yrs, 28 men) considered to be at increased risk for surgical aortic valve replacement were enrolled and examined before and 30 days after TAVR. All pts underwent a comprehensive echocardiogram, including speckle tracking echocardiography (STE) for deformation analysis. Longitudinal LA strain parameters were assessed from the apical 4-chamber view. Peak values of global longitudinal LA strain (LAε) and LA systolic strain rate (SSr, reservoir function) and early diastolic strain rate (ESr, conduit function) were measured in all. Contractile LA function (late diastolic strain rate, ASr) was assessed in patients in sinus rhythm (39 pts). Results Compared with baseline, the mean indexed LV mass was significantly reduced after TAVR (141 ± 26 vs 160 ± 37 g/m2, p = 0.009) but the mean increase in LVEF was not statistically significant (51 ± 14% vs 47 ± 15%, p = 0.2). There was a significant reduction in systolic pulmonary pressure after TAVR (34 ± 12 vs 42 ± 13, p = 0.004). Although there was no significant decrease in indexed LA volume (51 ± 22 vs 56 ± 20 ml/m2, p = 0.3), the contractile LA function significantly improved 30-days after TAVR (mean ASr, -1.1 ± 0.5 vs -0.8 ± 0.4 %, p = 0.02). There was a tendency of improvement in global longitudinal LA strain (15 ± 7 vs 12 ± 6%, p = 0.06) and global longitudinal LV strain (-13 ± 4 vs -11 ± 5%, p = 0.06) as well. Parameters of LV diastolic function, including TDI derived e’ and E/e’ ratios were not significantly improved 30 days after TAVI. While LA volumes and function parameters were not significantly different between genders at baseline, the improvement of LA function was more frequently found in male pts (p = 0.05). There were no significant correlations between the improvement of LA function parameters and baseline echocardiographic parameters in our study group. The only predictor of LA booster function improvement was the baseline value of ASr (p = 0.01). Conclusions TAVR is associated with a significant recovery of LA function as assessed by STE, suggesting a reverse cavity remodeling. This was accompanied by a significant reduction in LV mass and systolic pulmonary pressure. Men seem to show a more significant improvement in LA contractile function, suggesting a gender-related LA response to chronic afterload reduction.
