RESUMEN
Background: Transcatheter mitral valve replacement (TMVR) represents a novel treatment option for patients with mitral regurgitation (MR), but little is known about the hemodynamic impact of MR elimination following TMVR. We sought to investigate the hemodynamic impact of TMVR on left ventricular (LV) and right ventricular (RV) function using noninvasive pressure-volume loops. Methods: All consecutive patients undergoing TMVR with dedicated devices between May 2016 and August 2022 were enrolled. The end-diastolic and end-systolic pressure-volume relationships were estimated from 26 patients using single-beat echocardiographic measurements at baseline and after TMVR at discharge. RV function was assessed by RV-pulmonary artery (PA) coupling and RV fractional area change. One-year follow-up was available for 19 patients. The prognostic impact of calculated end-diastolic volume at an end-diastolic pressure of 20 mmHg (VPed20) reduction was assessed by Cox regression. Results: A total of 26 patients (77.0 years [interquartile range 73.9-80.1], N = 17 [65.4%] male) with successful TMVR were included (secondary MR [N = 21, 80.8%]; median LV ejection fraction was 37.0% [interquartile range 30.7-50.7]). At discharge, a decrease in VPed20 (p < 0.001) indicating leftward shift of end-diastolic pressure-volume relationship, and an increase of the end-systolic elastance slope (p = 0.007) were observed after TMVR. No changes were observed for RV-PA coupling (p = 0.19) and RV fractional area change (p = 0.22). At 1-year follow-up, LV contractility (end-systolic elastance) and RV-PA coupling remained stable. Vped20 reduction at discharge was significantly associated with 1-year all-cause mortality or heart failure hospitalization (hazard ratio 0.16, 95% CI 0.04-0.71, p = 0.016). Conclusions: Noninvasive assessment of pressure-volume loops demonstrated early LV reverse remodeling and improved LV contractility, while RV performance was preserved. These results indicate the potential prognostic impact of complete MR elimination after TMVR.

BACKGROUND: Transcatheter mitral valve replacement (TMVR) is a therapeutic option for patients with severe mitral regurgitation (MR) who are ineligible for conventional surgery. There are limited data on the outcomes of large patient cohorts treated with TMVR. AIMS: This study aimed to investigate the outcomes and predictors of mortality for patients treated with transapical TMVR. METHODS: This analysis represents the clinical experience of all patients enrolled in the Tendyne Expanded Clinical Study. Patients with symptomatic MR underwent transapical TMVR with the Tendyne system between November 2014 and June 2020. Outcomes and adverse events up to 2 years, as well as predictors of short-term mortality, were assessed. RESULTS: A total of 191 patients were treated (74.1±8.0 years, 62.8% male, Society of Thoracic Surgeons Predicted Risk of Mortality 7.7±6.6%). Technical success was achieved in 96.9% (185/191), and there were no intraprocedural deaths. At 30-day, 1- and 2-year follow-up, the rates of all-cause mortality were 7.9%, 30.8% and 40.5%, respectively. Complete MR elimination (MR <1+) was observed in 99.3%, 99.1% and 96.3% of patients, respectively. TMVR treatment resulted in consistent improvement of New York Heart Association Functional Class and quality of life up to 2 years (both p<0.001). Independent predictors of early mortality were age (odds ratio [OR] 1.11; p=0.003), pulmonary hypertension (OR 3.83; p=0.007), and institutional experience (OR 0.40; p=0.047). CONCLUSIONS: This study investigated clinical outcomes in the full cohort of patients included in the Tendyne Expanded Clinical Study. The Tendyne TMVR system successfully eliminated MR with no intraprocedural deaths, resulting in an improvement in symptoms and quality of life. Continued refinement of clinical and echocardiographic risks will be important to optimise longitudinal outcomes.

BACKGROUND: The impact of intraprocedural results following transcatheter edge-to-edge repair (TEER) in primary mitral regurgitation (MR) is controversial. OBJECTIVES: This study sought to investigate the prognostic impact of intraprocedural residual mitral regurgitation (rMR) and mean mitral valve gradient (MPG) in patients with primary MR undergoing TEER. METHODS: The PRIME-MR (Outcomes of Patients Treated With Mitral Transcatheter Edge-to-Edge Repair for Primary Mitral Regurgitation) registry included consecutive patients with primary MR undergoing TEER from 2008 to 2022 at 27 international sites. Clinical outcomes were assessed according to intraprocedural rMR and mean MPG. Patients were categorized according to rMR (optimal result: ≤1+, suboptimal result: ≥2+) and MPG (low gradient: ≤5 mm Hg, high gradient: > 5 mm Hg). The prognostic impact of rMR and MPG was evaluated in a Cox regression analysis. The primary endpoint was 2-year all-cause mortality or heart failure hospitalization. RESULTS: Intraprocedural rMR and mean MPG were available in 1,509 patients (median age = 82 years [Q1-Q3: 76.0-86.0 years], 55.1% male). Kaplan-Meier analysis according to rMR severity showed significant differences for the primary endpoint between rMR ≤1+ (29.1%), 2+ (41.7%), and ≥3+ (58.0%; P < 0.001), whereas there was no difference between patients with a low (32.4%) and high gradient (42.1%; P = 0.12). An optimal result/low gradient was achieved in most patients (n = 1,039). The worst outcomes were observed in patients with a suboptimal result/high gradient. After adjustment, rMR ≥2+ was independently linked to the primary endpoint (HR: 1.87; 95% CI: 1.32-2.65; P < 0.001), whereas MPG >5 mm Hg was not (HR: 0.78; 95% CI: 0.47-1.31; P = 0.35). CONCLUSIONS: Intraprocedural rMR but not MPG independently predicted clinical outcomes following TEER for primary MR. When performing TEER in primary MR, optimal MR reduction seems to outweigh the impact of high transvalvular gradients.

BACKGROUND: Residual transprosthetic gradient (TG) after transcatheter aortic valve replacement (TAVR) with balloon-expandable valves (BEV) may be due to suboptimal valve expansion. AIMS: To compare hemodynamics after TAVR with small BEV according to postdilation strategy. METHODS: This observational, retrospective cohort study included 184 consecutive patients from a single center treated with 23 mm Sapien 3 Ultra (Edwards Lifesciences) BEV implantation in the aortic position and enrolled between January 2020 and April 2023. Patients treated with routine postdilation (RP, n = 73) were compared to patients treated according to local standard practice (SP, n = 111). Primary endpoint was 30-day mean TG. Secondary endpoints were incidence of 30-day prosthesis-patient mismatch (PPM), technical success and device success. RESULTS: Thirty-day mean TG was lower in RP versus SP (12.3 ± 4.6 mmHg vs. 14.1 ± 5.7 mmHg, p = 0.031), and incidence of PPM was less common with RP versus SP (47.3% vs. 71.0%, p = 0.006). Technical success (98.6% vs. 99.1%, p = 0.637) and device success (93.1% vs. 90.1%, p = 0.330) did not differ between groups. Differences in 30-day mean TG were driven by patients at normal flow (12.1 ± 4.0 mmHg vs. 15.0 ± 5.5 mmHg, p = 0.014), while no differences were evident among patients at low flow (12.5 ± 5.5 mmHg vs. 11.7 ± 5.5 mmHg, p = 0.644). RP decreased height and increased width of BEV, and a linear regression established that final BEV width could predict 30-day mean TG (r = -0.6654, p < 0.0001). CONCLUSIONS: RP after TAVR with small BEV was associated with more favorable forward-flow hemodynamics than SP.
RESUMEN
BACKGROUND: Obstructive defecation syndrome (ODS) defines a disturbed defecation process frequently associated with pelvic organ prolapse (POP) in women that substantially compromises quality of life. Conservative management offers limited relief and a surgical intervention may be required. This is characterized by individual approaches. AIM OF THE STUDY: This retrospective single center study evaluated the surgical and clinical short-term outcome of a novel interdisciplinary laparoscopic resection rectopexy (L-RRP) with mesh- sacrocolpopexy (L-SCP) for women suffering from ODS and POP. METHODS: The study participants underwent surgery in an interdisciplinary laparoscopic approach. Safety was the primary endpoint, assessed via postoperative morbidity classified by Clavien-Dindo scale. Secondary outcomes included evaluation of bowel function, fecal and urinary incontinence and pelvic organ prolapse status at 12 months follow-up. Additionally, a biological mesh (BM) was offered to women, who asked for an alternative to synthetic mesh material (SM). RESULTS: Of the 44 consecutive patients requiring surgery for ODS and POP, 36 patients underwent the interdisciplinary surgical approach; 28 patients with SM and 8 patients with BM. In total 5 complications occurred, four of them were classified as minor. One minor complication was observed in the BM group. One anastomotic leakage occurred in the SM group. The two ODS scores, the bowel dysfunction score, and the incontinence score improved significantly (p = 0.006, p = 0.003, p < 0.001, and p = 0.0035, respectively). Pelvic floor anatomy was fully restored (POP-Q 0) for 29 (80%) patients after surgery. 17 patients (47%) suffered from urinary incontinence before surgery, which was restored in 13 patients (76.5%). CONCLUSIONS: The interdisciplinary approach with L-RRP and L-SCP and the use of a BM in a small subgroup were technically feasible, safe, and effective in this single center setting. The study's retrospective design, the small sample size and the lack of comparators limit the generalizability of the findings requiring future randomized trials. TRIAL REGISTRATION: Retrospectively registered at clinicaltrials.gov, trial number NCT05910021, date of registration 06/10/2023.

BACKGROUND: Aortic valve calcification (AVC) indexation to the aortic annulus (AA) area measured by Doppler echocardiography (AVCdEcho) provides powerful prognostic information in patients with aortic stenosis (AS). However, the indexation by AA measured by multidetector computed tomography (AVCdCT) has never been evaluated. The aim of this study was to compare AVC, AVCdCT, and AVCdEcho with regard to hemodynamic correlations and clinical outcomes in patients with AS. METHODS: Data from 889 patients, mainly White, with calcific AS who underwent Doppler echocardiography and multidetector computed tomography within the same episode of care were retrospectively analyzed. AA was measured both by Doppler echocardiography and multidetector computed tomography. AVCdCT severity thresholds were established using receiver operating characteristic curve analyses in men and women separately. The primary end point was the occurrence of all-cause mortality. RESULTS: Correlations between gradient/velocity and AVCd were stronger (both P≤0.005) using AVCdCT (r=0.68, P<0.001 and r=0.66, P<0.001) than AVC (r=0.61, P<0.001 and r=0.60, P<0.001) or AVCdEcho (r=0.61, P<0.001 and r=0.59, P<0.001). AVCdCT thresholds for the identification of severe AS were 334 Agatston units (AU)/cm2 for women and 467 AU/cm2 for men. On a median follow-up of 6.62 (6.19-9.69) years, AVCdCT ratio was superior to AVC ratio and AVCdEcho ratio to predict all-cause mortality in multivariate analyses (hazard ratio [HR], 1.59 [95% CI, 1.26-2.00]; P<0.001 versus HR, 1.53 [95% CI, 1.11-1.65]; P=0.003 versus HR, 1.27 [95% CI, 1.11-1.46]; P<0.001; all likelihood test P≤0.004). AVCdCT ratio was superior to AVC ratio and AVCdEcho ratio to predict survival under medical treatment in multivariate analyses (HR, 1.80 [95% CI, 1.27-1.58]; P<0.001 compared with HR, 1.55 [95% CI, 1.13-2.10]; P=0.007; HR, 1.28 [95% CI, 1.03-1.57]; P=0.01; all likelihood test P<0.03). AVCdCT ratio predicts mortality in all subgroups of patients with AS. CONCLUSIONS: AVCdCT appears to be equivalent or superior to AVC and AVCdEcho to assess AS severity and predict all-cause mortality. Thus, it should be used to evaluate AS severity in patients with nonconclusive echocardiographic evaluations with or without low-flow status. AVCdCT thresholds of 300 AU/cm2 for women and 500 AU/cm2 for men seem to be appropriate to identify severe AS. Further studies are needed to validate these thresholds, especially in diverse populations.

Early spliceosome assembly can occur through an intron-defined pathway, whereby U1 and U2 small nuclear ribonucleoprotein particles (snRNPs) assemble across the intron1. Alternatively, it can occur through an exon-defined pathway2-5, whereby U2 binds the branch site located upstream of the defined exon and U1 snRNP interacts with the 5' splice site located directly downstream of it. The U4/U6.U5 tri-snRNP subsequently binds to produce a cross-intron (CI) or cross-exon (CE) pre-B complex, which is then converted to the spliceosomal B complex6,7. Exon definition promotes the splicing of upstream introns2,8,9 and plays a key part in alternative splicing regulation10-16. However, the three-dimensional structure of exon-defined spliceosomal complexes and the molecular mechanism of the conversion from a CE-organized to a CI-organized spliceosome, a pre-requisite for splicing catalysis, remain poorly understood. Here cryo-electron microscopy analyses of human CE pre-B complex and B-like complexes reveal extensive structural similarities with their CI counterparts. The results indicate that the CE and CI spliceosome assembly pathways converge already at the pre-B stage. Add-back experiments using purified CE pre-B complexes, coupled with cryo-electron microscopy, elucidate the order of the extensive remodelling events that accompany the formation of B complexes and B-like complexes. The molecular triggers and roles of B-specific proteins in these rearrangements are also identified. We show that CE pre-B complexes can productively bind in trans to a U1 snRNP-bound 5' splice site. Together, our studies provide new mechanistic insights into the CE to CI switch during spliceosome assembly and its effect on pre-mRNA splice site pairing at this stage.

(1) Background: Transfemoral transcatheter aortic valve implantation (TAVI) has become the standard treatment for most patients with severe symptomatic aortic stenosis. Intravascular lithotripsy may facilitate transfemoral TAVI (IVL-TAVI) even in patients with severely calcified iliofemoral disease. We assessed technical aspects and clinical outcomes of this novel approach compared to alternative transaxillary access (TAX-TAVI). (2) Methods: IVL-TAVI was performed for severe iliofemoral calcifications precluding standard transfemoral access in 30 patients from 2019 to 2022 at a single academic heart center. IVL was performed as part of the TAVI procedure in all cases. Results were compared to a control group of 44 TAX-TAVI procedures performed for the same indication from 2016 to 2021. The safety outcome was a composite of all-cause death, stroke, access-related bleeding ≥ type 2 within 24 h and major vascular access site complications at 30 days. The efficacy outcome was defined as a technical success according to VARC-3. (3) Results: Median age was 78.2 [74.3, 82.6] years, 45.9% were female and mean STS-PROM was 3.6% [2.3, 6.0]. Iliofemoral calcifications were more severe in the IVL-TAVI vs. TAX-TAVI groups (lesion length: 63.0 mm [48.6, 80.3] vs. 48.5 mm [33.1, 68.8]; p = 0.043, severe calcification at target lesion: 90.0% vs. 68.2%; p = 0.047, and median arc calcification 360.0° [297.5, 360.0] vs. 360.0° [180.0, 360.0]; p = 0.033). Technical success was achieved in 93.3% vs. 81.8% (p = 0.187) in IVL- and TAX-TAVI and the safety outcome occurred in 10.0% vs. 31.8% in IVL- and TAX-TAVI (p = 0.047), respectively. (4) Conclusions: IVL-assisted transfemoral TAVI was feasible and safe with favorable outcomes compared to TAX-TAVI. IVL may further expand the number of patients eligible for transfemoral TAVI and may help overcome limitations of an alternative access.
RESUMEN
BACKGROUND: Data on the prognostic role of the TRI-SCORE in patients undergoing transcatheter tricuspid valve intervention (TTVI) are limited. OBJECTIVES: The aim of this study was to evaluate the performance of the TRI-SCORE in predicting outcomes of patients undergoing TTVI. METHODS: TriValve (Transcatheter Tricuspid Valve Therapies) is a large multicenter multinational registry including patients undergoing TTVI. The TRI-SCORE is a risk model recently proposed to predict in-hospital mortality after tricuspid valve surgery. The TriValve population was stratified based on the TRI-SCORE tertiles. The outcomes of interest were all-cause death and all-cause death or heart failure hospitalization. Procedural complications and changes in NYHA functional class were also reported. RESULTS: Among the 634 patients included, 223 patients (35.2%) had a TRI-SCORE between 0 and 5, 221 (34.8%) had 6 or 7, and 190 (30%) had ≥8 points. Postprocedural blood transfusion, acute kidney injury, new atrial fibrillation, and in-hospital mortality were more frequent in the highest TRI-SCORE tertile. Postprocedure length of stay increased with a TRI-SCORE increase. A TRI-SCORE ≥8 was associated with an increased risk of 30-day all-cause mortality and all-cause mortality and the composite endpoint assessed at a median follow-up of 186 days (OR: 3.00; 95% CI: 1.38-6.55; HR: 2.17; 95% CI: 1.78-4.13; HR: 2.08, 95% CI: 1.57-2.74, respectively) even after adjustment for procedural success and EuroSCORE II or Society of Thoracic Surgeons Predicted Risk of Mortality. The NYHA functional class improved across all TRI-SCORE values. CONCLUSIONS: In the TriValve registry, the TRI-SCORE has a suboptimal performance in predicting clinical outcomes. However, a TRISCORE ≥8 is associated with an increased risk of clinical events and a lack of prognostic benefit after successful TTVI.

BACKGROUND: Previous reports suggest septal hypertrophy with an interventricular septum depth (IVSD) ≥ 14 mm may adversely affect outcomes after transcatheter aortic valve implantation (TAVI) due to suboptimal valve placement, valve migration, or residual increased LVOT pressure gradients. AIMS: This analysis investigates the impact of interventricular septal hypertrophy on acute outcomes after TAVI. METHODS: Between 2009 and 2021, 1033 consecutive patients (55.8% male, 80.5 ± 6.7 years, EuroSCORE II 6.3 ± 6.5%) with documented IVSD underwent TAVI at our center and were included for analysis. Baseline, periprocedural, and 30-day outcome parameters of patients with normal IVSD (< 14 mm; group 1) and increased IVSD (≥ 14 mm; group 2) were compared. Data were retrospectively analyzed according to updated Valve Academic Research Consortium-3 (VARC-3) definitions. Comparison of outcome parameters was adjusted for baseline differences between groups using logistic and linear regression analyses. RESULTS: Of 1033 patients, 585 and 448 patients were allocated to groups 1 and 2, respectively. There was no significant difference between groups regarding transfemoral access rate (82.6% (n = 478) vs. 86.0% (n = 381), p = 0.157). Postprocedural mean transvalvular pressure gradient was significantly increased in group 2 (group 1, 7.8 ± 4.1 mmHg, vs. group 2, 8.9 ± 4.9 mmHg, p = 0.046). Despite this finding, there was no significant difference between groups regarding the rates of VARC-3 adjudicated composite endpoint device success (90.0% (n = 522) vs. 87.6% (n = 388), p = 0.538) or technical success (92.6% (n = 542) vs. 92.6% (n = 415), p = 0.639). Moreover, the groups showed no significant differences regarding the rates of paravalvular leakage ≥ moderate (3.1% (n = 14) vs. 2.6% (n = 9), p = 0.993), postprocedural permanent pacemaker implantation (13.4% (n = 77) vs. 13.8% (n = 61), p = 0.778), or 30-day mortality (5.1% (n = 30) vs. 4.5% (n = 20), p = 0.758). CONCLUSION: Although transvalvular mean pressure gradients were significantly higher in patients with increased IVSD after TAVI, acute outcomes were comparable between groups suggesting no early impact of adverse hemodynamics due to elevated IVSD. However, how these differences in hemodynamic findings may affect mid- and long-term outcomes, especially in terms of valve durability, needs to be evaluated in further investigations.
RESUMEN
AIMS: T-TEER is an effective therapy for the treatment of tricuspid regurgitation (TR). However, the effects of leaflets clipping on tricuspid valve annulus (TA) have not been investigated in detail. The aim of this study is to investigate the effects of tricuspid transcatheter edge-to-edge repair (T-TEER) on TA diameter. METHODS AND RESULTS: The TriValve registry (Transcatheter Tricuspid Valve Therapies, NCT03416166) collected 556 patients from 22 European and North American centres undergoing transcatheter tricuspid valve interventions from 2016 to 2022. Patients undergoing T-TEER with available pre- and post-procedural data on TA diameter measured in the apical 4-chamber view on transthoracic echocardiography were selected for this study. Primary end-point was the reduction of TA diameter after T-TEER. A total of 186 patients were included in the study. In 115 patients (62%) TA diameter was reduced by at least 1 mm as compared to baseline. A significant reduction of TA dimension was observed following T-TEER (mean 2.3 mm [from pre-procedural diameter 46.7 mm to post-procedural diameter 44.4 mm], p < 0.001). In particular, the greatest reduction was observed in those with T-TEER in antero-septal commissure (mean 2.7 mm [from 47.1 mm to 44.4 mm], p < 0.001) as compared to those combining both antero-septal and postero-septal commissures (mean 1.4, from 46.0 mm to 44.6 mm, P = 0.06). A significant reduction of TA dimension was recorded in patients with 1 or 2 clips implanted but not in those patients with ≥3 clips implanted. CONCLUSIONS: In almost two third of patients T-TEER reduces TA diameter in addition to leaflet approximation. CONDENSED ABSTRACT: The effects of tricuspid transcatheter edge-to-edge repair (T-TEER) on tricuspid valve annulus (TA) have not been studied in details. This study investigates TA diameter as measured in apical 4-chamber view on transthoracic echocardiography before and after T-TEER. A total of 186 patients from the TriValve registry were included in the study. The study results show that 62% of patients have a TA reduction after T-TEER, especially in those receiving 1 or 2 clips in the antero-septal commissure. These suggest that T-TEER reduces tricuspid regurgitation not only by approximation of leaflets, but also by TA diameter reduction.

OBJECTIVES: Relevant paravalvular leakage (PVL) due to prosthesis dislodgement is a rare but potentially severe complication after transcatheter mitral valve implantation (TMVI). Due to the epicardial anchoring mechanism of the Tendyne® TMVI system, repositioning of the valve stent may be possible by retensioning of the tether. This multicentre study aimed to investigate the procedural and short-term safety as well as efficacy of retensioning manoeuvres. METHODS: From 2017 to 2021, N = 18 patients who underwent secondary tether retensioning were identified. Baseline, procedural and follow-up data were available from N = 11 patients and analysed according to the Mitral Valve Research Consortium definitions. Continuous variables are shown as median with interquartile range. RESULTS: All patients [age 75 years (73.5, 85.0), 64% male (N = 7), EuroSCORE II 6.2% (5.8, 11.6)] presented with post-procedural PVL [63.6% (N = 7) with PVL ≥3+]. Of these, 54% (N = 6) showed signs of haemolysis. The majority were severely symptomatic [New York Heart Association ≥III (91%, N = 10)]. Procedural outcomes revealed no acute complications and no mortality. At discharge, PVL was completely eliminated in 91% (N = 10) of patients with 1 case of remaining moderate PVL. At 30 days, Mitral Valve Research Consortium device success was achieved in 82% (N = 9) of patients. Two patients required open surgical mitral valve replacement due to persistent and recurrent PVL. In 89% (N = 8) of patients with successful retensioning procedure, New York Heart Association class was I/II. There was no 30-day mortality. CONCLUSIONS: This multicentre study demonstrates technical feasibility, procedural safety and acute efficacy of retensioning procedures in the majority of patients. The potential to retension the tether in transapical TMVI may provide additional management advantages in populations at high surgical risk.

BACKGROUND/AIM: At the beginning of the 21st century, obstetric medicine took a turn from interventional to restrictive in low-risk birth. The present study examined the changes in peripartum management over the past 20 years at the Women's University Hospital Cologne. The attitudes of the becoming mother and physicians towards anesthesia, episiotomy, and vaginal-operative deliveries were compared and the factors influencing the duration of birth over the past 20 years were examined. PATIENTS AND METHODS: In this retrospective study, the low-risk singleton birth of 955 in 2000/2001 and 944 births in 2018 at the Women's University Hospital Cologne were analyzed. RESULTS: The age of women who tended to give birth has significantly increased at present compared to 20 years ago. In 2018, labor was induced significantly more often than in 2000/2001. The rate of vaginal operative deliveries has fluctuated between 15% and 20% in the last 20 years. Forceps are no longer used. The use of episiotomy has taken a fundamental turn in the last 20 years. Prophylactic episiotomy is not performed anymore, most vaginal operative deliveries take place without the episiotomy. The birth duration has been significantly shortened at present compared to 20 years ago. CONCLUSION: Pregnancy and childbirth over the last years are not considered as a disease, but as a natural course, and the trend of minimizing interventions in low-risk delivery has a positive effect on childbirth.
